I would love to see a impulse response in adition to a frequency response. Frequency response is just one side of a coin. I witnessed poor sounding speakers wich had a well balanced frequency response.
@@PierreVilleneuve88 It is, but impulse response looks at things from a different way, you might be able to see ringing a little better, than the broad overview that a spectral decay offers. Though it can take more work. He's already doing far more than nearly anyone in the industry, so people should cut him slack for the thousands of man hours behind the scene's.
I've used Dynaudio drivers in DIY builds for close to 30 years and I have never seen any of their woofers have a peak like that. Most are very flat over their intended range of use. Not saying your measurements are wrong, just never seen it before. Also Dynaudio cones are not a simple polypropylene.
Truth hurts my man, measurements don't lie, these speakers are junk for 3k, even those cheap Sony's destroy them, especially after his mods. I've seen other people measure these 3k paper weights, nearly the same result...
Literally the first time I heard spoken a negative sentence about this speaker. I'll have to be honest, the way I heard it, I liked it. And I think it's generally a bit of a specific taste, upgraded or stock.
Has everyone on here that bashes every brand reviewed ever looked inside the boxes of their electronics or do they also build their own electronics? You're in for a shock if you look inside. Is every kit GR sells beyond reproach or have compromises also been made and further improvements could still be had? Buy what sounds good to you and move on. If the Dynaudios were $2000 would people here be more accepting, not likely, they'd still complain and say they got ripped off. It's hilarious. If you only want to pay the cost of the BOM build your own, I'm sure they'll sound perfect and be super ugly.
There is no such thing as intrinsic value. There is only the value assigned to a product by the purchasers wallet. If these speakers had included all the crossover parts Danny believes they should would anyone who thinks these speakers are a rip off as is suddenly think they're a good deal? Well, if you answered yes you're not thinking clearly. Yes, the crossover parts Danny recommends are more expensive but not even remotely close to being enough to warrant a $3000 price tag based on parts content alone. If you want great overall value from a parts versus performance price then build yourself a kit. Like, seriously, almost any kit. Buy Danny's kit. Buy a kit from Madisound or Parts Express or any of a variety of other sources and you will definitely get more for your money than any commercial speaker will give you. Every product on earth costs more than it's parts content alone and no one man is the absolute arbitor of what those parts should be regardless of price. Are the parts Danny recommends better than what came from the factory? Technically speaking, absolutely. But will changing out the factory parts for the GR-Research parts make this speaker the performance equivalent of a top notch $3000 kit? Not even close! Heck, many people will prefer the sound before the parts change. As I've said before on this channel. It's your money, spend it how you wish. But all anyone can do no matter how skilled they are with speaker design is change, not fix, the sound. The end result of that change may or may not sound better to you. Some people like a bass or midrange bump. Some people like recessed mids or high or even thin bass. Geez, I think some of y'all would sell your house if Danny came along and found that your wall studs, though perfectly safe and installed correctly were southern yellow pine instead of Douglas fir. If it works, you like it and feel it's worth the money, buy it. But If you're buying $3000 bookshelf speakers in the first place, well, I'd say that no matter how good the parts are inside, your perception of value is too skewed to worry about anyway!
When you spend the money you also invest in a company. The level of components you get for your money is only a fraction of the value you get in return. If you want the manufacturer to pay salaries, rent office space, do research and development etc then you assume your 3k isn't getting you 3k in parts. The product you receive is only a fraction of that. If it weren't, there would be no company to buy speakers from
I am kind of confused after 30 years of Hifi and DIY speaker building looking at all your videos. Seems you think to increase sound of every commercial speaker by flattening the frequency response on axis and 30°. But is it that easy? To be honest: I did not hear any of your own speakers or any speakers modified by you. But I am kind of struggeling to believe becuase from my experience the big companies like Dynaudio know very well about speaker sound refinement. What about impulse response or THD in higher power levels? I cannot believe changing poly caps to more expensive poly caps and corretly rated iron inductors changing to air inductors change the world. (and I have changed many poly caps in my live) From my opinion it is more the developer feeling to understand how to adjust the crossover to get the speaker sound good. And I believe that Dynaudio for sure recruted the best developers for the job.
Hi GR-Research, please give me a response so that I can understand it. I am at least not a complete noop , german diploma in electric engineering since 19 years. so I think I should potentially be capable to understand what you would explain.
@Thorsten Hoffmann Give him a phone call, I called him once because I was having trouble ordering no-rez product on his website. He was nice and helpful. However, I wouldn't expect him to have a long conversation, he's busy running his company.
This chap still believes into significant differences between cables, capacitors and coils. I tried this in the 1980's (young ears) several times without result. Useless approach, except for the providers of such parts. Buy better speakers, if you are not happy, and please do not waste money on esoteric nonsense!
While I agree that changes in some of those will not alter the audio signature, he does show actual improvements in objective measurements from the upgrades. Regardless, he's right in that for that $, it should not be full of low grade parts. That brand seems a terrible value for $.
@@willbrink Sorry mate, but he is straight up lying to you and then you repeat it. 1) He did not fix anything - all he did is change the frequency response - which he can do, but that does not make the speaker better just because it is flatter. 2) Dynaudio is one of the best known brands for their high quality speakers with top notch parts. That is the reason why a pair of Focus 340 I bought used 5 years ago 2.000€ are still worth that money now. 3) This has nothing to do with dollers - these aren't your typical cheaply made American speakers - these are done by engineers from Denmark. To each his own - if you don't like Dynaudio or you aren't even into hifi - fine with me, but stop repeating something without doing your research.
@@zebarzebra 1) He did not fix anything - all he did is change the frequency response - which he can do, but that does not make the speaker better just because it is flatter.

For that $, those are low end parts. 3) This has nothing to do with dollers - these aren't your typical cheaply made American speakers - these are done by engineers from Denmark. A: Of course has to do with dollars, and some companies charge a fair price for they offer, some, not so much. Like speakers from Europe, US speakers ranges from very well made to not so great, and what matters is what they cost for the value. As far "done by engineers from Denmark" you're poorly informed: "Dynaudio is a chinese company with a chinese majority owner. Some of the lower lines are FULLY MADE IN CHINA. The cabinets are outsourced, and the higher lines are assembled in Denmark." Dynaudio was acquired by Goertek in 2014 To each his own - if you don't like Dynaudio or you aren't even into hifi - fine with me, but stop repeating something without doing your research. A: Not I who needs to do their research obviously...
@@willbrink Dynaudio is a Danish company, owned by Chinese. It is located in Skanderborg, 30 km from where I live. 250 of their 350 employees work there. All development happens there. According to their website, production also happens there. The latest info on cabinet production, is from 2018, and it says that their cheapest models' cabinets are produced in their own facilities in Latvia.
@@franciscoortiz6980 This guy is very funny 😆 I have those speakers for more than a year. They are not perfect but they really play music. Excellent speakers. Very difficult to replace after you got used to their sound signature. I tried.. but still have them. Addictive sound
I've had the Dynaudio Special 40s for about 3 years now, driving them with a NAD C-390DD and they sound incredible. Absolutely incredible. And I listen to a lot of speakers in that price range and higher before I purchased. I understand the measurements but I'll trust my ears and the ears of many reviewers and users who also love them.
You can see that the quality of components used in the Heritage is far higher as it should be for the price. This kit will bring you close to the Heritage for a few hundred.
This seems like a man who is just trying to sell his crossover kit. It doesn’t really matter how they measure on paper, it matters how they sound. That’s what you’re paying for. And these speakers sound pretty damn amazing and are worth every penny.
These speakers are far from amazing. Our $269 X-LS Encore kit eats them up. And check out the feedback from a customer below that bought this upgrade. " Phantom Plastics 2 months ago I bought this kit and they sound far, far better with the kit."
@@dannyrichie9743 I’m not an idiot. I’ve listened to these speakers myself, and even own a pair of Evoke 20. Dynaudio even says in one of their videos on their TH-cam channel how “what might look right on paper, doesn’t always sound right to the human ear.” They spend years tuning their speakers before putting them out, and you think that you can make them better? LOL. The fact that you even tried to compare Sony with a brand like Dynaudio just shows that you have absolutely no clue what a good speaker sounds like. Maybe you should get your hearing checked. I also use to work in sales myself, so I know the tactics that a salesman uses.
@@blue-ck9ns You are just fooling yourself if you think Dynaudio spent years tuning their speakers only to send them out with an irregular or non linear response with a bunch of ringing at 1kHz. Do you really think that ringing is something they intended? It is an inherent problem with the woofer that they failed to address. And they are loaded with budget level parts. No need to have my hearing checked either. Anyone that is not deaf can hear the improvements this upgrade offers. Check out the response below from and actual customer that bought this upgrade: Phantom Plastics: 5 months ago (edited) Sold! - UPDATE - I bought this upgrade. It's easy to install, even for a complete novice. The sound is much clearer and more engaging now. Transients are faster with much more impact. I was actually startled at one point. Female vocalists like Mary Chapin Carpenter now have a lifelike breathy quality and the soundstage is way more open. This is the kind of upgrade I would expect from buying the Special Heritage which cost $7K (co-incidentally, that has similar quality parts to what GR Research offer for a few hundred dollars). Try it and be amazed.
@@blue-ck9ns People are not worried about their warranty. They want the high quality performance that they thought they would get when they bought these.
I believe these speakers were supposed to be "fun" and were voiced accordingly. Dynaudio certainly has a house sound, much like Harbeth or Sonus Faber, etc. that you either like or don't like. Fixing the cabinet resonance and flattening the curve (especially without consideration of the speaker's polar response or the room) is counterproductive and will absolutely ruin the resale value. If you want a "neutral" sounding monitor you should just purchase one to begin with.
Actually, the polar response has been improved as well. Also, only part of the upgrade is balancing out the response. That nasty woofer resonance is not part of a house sound either. They just neglected to correct it, and it needed correcting. These were also being held back by the parts quality. The upgrade is a transformation from a lifeless and problematic speaker into a pretty decent speaker.
@@jespergth9437 Then i appoligize. But surely you get my drift about spending a relatively small percentage of a speaker's $3000 price to flatten-out such a lumpy & hence "unfaithful to whatever the source's" intended frequency reproduction, of course we don't always get a chance to know of such a potential 'massive' improvement for every potential speaker purchase, but if i'd bought this particular model, because it sounded good in the 1'st place, then after seeing this vid i'd be ultra-keen to take the extra monetary step to extract the best out of it, especially after seeing the before & after graphs showing the magnitude of difference this upgrade made. if it was my main hi-fi listening source, which any $3000 speaker would have to be (in my wealth bracket, or lack of) Good luck
@@The-Spotlight-Kid not so sure about if the "new parts" actually make it sound better. i dont think its that simple. Those "high qualiity" parts might completely destrpy they sound of those speakers. GR-Research is in the business of selling upgrade kits. OFC they claim that simply changing part to another will improve the sound. or changing graph will improve the sound... afaik, its not that simple and straightforward. if it was, most hifi companies would use those parts.
Spending 3 grand on a pair of speakers, you shouldn't have to spend another $300 dollars to make them sound better, it should be done at the factory where they are made
I really would like an actual listening test before and after, just like how cables should be treated. Nothing against measurements, but listening is the real test. At least in my opinion.
That's the thing I feel is missing from the content on this channel. Measurements are great but speakers are made to sound appealing, and measurements are only one part of this.
@@IDontExist14 Obviously, and thats ok, I'm sure that the kits improve the speakers. I suppose since audio is such a subjective thing (what we enjoy) the only way to really "improve" something is to try to use objective means.
@@RyChanneler only noobs fall for this guy, if a flat response is all u want then everyone can make a world class speaker, don't u think dynaudio couldn't get a flat repsonce for 3k dollars, plz consult someone who is well versed in audio and has actually made speakers from sratch
If the parts are so bad, how the speaker sound so good? Maybe because there are 40 years of research and development behind this speaker? How do you calculate 40 years of R&D into the speaker price?
Still have them. Now with McIntosh. They are kind of dense in the mids but sound good with any music. Bass is perfect. Wanted to replace them with more transparent and expensive speaker but returned to the SP40 after a week. Very musical and pleasant speaker with good bass. This guy in the video don’t really know what he’s talking about. Funny guy 😄😄
Well, to me the FR plot after the “upgrade” looks worse than the original on some frequencies, while he flattened a bit the 1K region he also created a deeper valley on the 6K region, also I don’t buy the individual “woofer measurements”, since the woofer has been tweaked to work along with the original crossover, what I would ONLY do is replacing the inexpensive parts in the crossover with higher quality parts but keeping the original values.
My point is actually a bit different - I'm not so sure the tweeter is able to handle low x-o freq proposed in the upgrade. While the bump in midwoofer freq response looks terrible, most 6" drivers have the cone edge artifact. To me the crossover could be optimized better from the factory, but I wouldn't cut the tweeter so low unless I'm 100% certain it can take the extra signal without introducing it's own distortions. Actually I have nothing against the original voicing of this speaker.
The drivers are just pulled of a shelf and the crossover and box is designed to suit. They basically only make 1 bass/mid driver, in various sizes. They all have the same motor, the same cone material and basically the exact same T/S parameters apart from the sensitivity, resonant frequency and overall bandwidth. So any speaker they make using this driver with the 3 inch coil is going to have the exact same issue. Even the cars like VW that have these drivers just with a plastic basket I bet have the exact same issue, unless its caused by the basket but the frequency is way to high to be caused by solid cast alloy
The thing is that I don’t get why the original crossover has to be flawed, every hi-fi loudspeaker on the market has its signature sound, if you want a flatter FR go get studio monitors period, I myself own the S40’s, I can tell you that with the right electronics and the right placement these loudspeakers sound very life-like and sweet, I really like them, are there better loudspeakers?, of course there are, but at this price point these loudspeakers are very, very, very good at soundstage, dynamics and detail, besides that there’s no “perfect” speakers on the market, they all have colorations and distortion.
I think you are asking "why is the shape of the response a flaw and not a feature"? Well, I guess you could look at it that way. A song should be recorded perfectly, and a speakers job is to play the song back with nothing added or taken away. The speaker should never be able to make a song sound "better", only worse. A speaker that doesn't not play like a flat studio monitor is adding peaks and distortion information that should not be there, or it is taking away info that should be there. As I said, the song should be recorded perfectly so that when it is played back 1:1 with a flat playing speaker it sounds the best.
I think there is a misunderstanding about hi-fi loudspeakers and studio monitors loudspeakers, hi-fi speakers usually have some pleasant colorations, they could be on the neutral side of warm or they can be a bit bright, some others can have a slight V shaped sound, so a flat FR in hi-fi speakers is not always a desirable feature, in fact is not expected, this is what audiophiles are looking for, some audiophiles find flat FR speakers boring and uninvolving, but a flat FR is desirable for studio monitors. The S40’s are considered a balance sound loudspeakers with a touch of warmth and air at the top. This is why I find this kind of crossover “correction” completely pointless.

This is good to hear. By "complete novice," what do you mean? Could you please list the precise skills needed to upgrade these? I'm asking because I'm an S40 owner and have never tried to modify speakers. Thanks.
@@RingwurmD you just need to be able to solder and twist the component wires together as shown in the supplied circuit diagram. I had not seen a circuit diagram in 30 years and it was still easy. He has videos on how to solder too. If you want to instal the tube connectors then you need a drill and 7/16 bit (he has a video on that too).
The measured results are right there in this video. What bb foto has stated is a complete and total lie. If you look in the upper righthand corner of the measurements you'll see the word Clio. Clio is a measuring system. It doesn't model responses. Each measurement shown is an actual measurement made with a network on that speaker. Nothing I do is modeled.

@@dannyrichie9743 Danny I know a way how to make your TH-cam channel much more successful than it is even now. Just buy/ rent Randy the mic system off of Adorama and have it properly set up and do a before-and-after of the speaker that you're going to modify. Heck, you could even put the speaker together then ship it to Ron for him to do for a small fee it would make it worth your while! I promise you it would pay off huge. I realize you're going to have to modify the speaker and put it together unless you're sending it back to the customer to do it themselves!🤔🤔😉😉😇 It would put all these as you call them flat-earthers doubting opinions to rest. Wow, just watched Ron's channel as he just mentioned he's coming down to help you out! Man, you took my great advice even before I offered it!!🤔🤔🤭🤭🤭🤭😉😇😜 As you can see, I know what I'm talkin about and evidently so do you!😬
I like your videos and see where your coming from but I really don't understand why a speaker can't be sent and your company do the upgrades and send them back.not everyone can source there own cabinets and know how to open and recontact all the new parts.why don't you offer this service? .kind regards derek.
Would be great if this "expert" did some fact checking before posting this video, but maybe that's too much to expect! Speaker cable inside Special 40 is NOT cheap! It is VanDenHul The Snowline. Non-electrolytic capacitors are Mundorf capacitors.
Dynaudio does use Mundorf in some of their higher end speakers. However these are probably Bennic. My Dyn 52se's have Bennic I believe. I took a peek in there.
Obviously you didn't read the full review by stereophile and they know what their listening to after comparing speakers over the last 30 plus years. Do you listen to the speakers before you mod them for your own profit.
I don't have to read what someone else thinks to see what's wrong with them. And John Atkinsons measurements looked a lot like mine. He also commented on the woofer break up at 1.1kHz and the cabinet wall resonances. And yes, I've heard these speakers before.
time and time again, what one is really buying when they go up the line, is a furniture grade enclosure. thats 90 % of the cost. rarely, if ever, do they use true audiophile parts internally, even with exceptional drivers. to some degree, one is buying a "conversation" piece for their home , and with it high WAF:
Well, Dynaudio was acquired by a large Chinese consortium in 2015 or so. When that happens, expect everything you know from your favourite brand to go to s***.
It's kind of the heaviest, with bad numbers. It completely changes the signal speed in the cable. Lightest is the best, with air inside,. Best is air, bur technically difficult. Some high-end even goes for cotton, yep grandma's underware cotton, like Duelund.
Sad but true and very obvious. They are also no longer designed in some facility in Denmark. They are owned by a China based company and assembled there as well.
The problem with 'upgrading' crossovers like this, is the assumption that perfectly flat is the best way a speaker could measure. What makes a dynaudio sound different from a KEF or a Focal speaker in large part is those little peaks and valleys through the EQ range which either accentuate or soften certain frequencies. Making it flatter isn't inherently better, it's just different. As far as wiring quality, etc. it's been pretty well disproven that that stuff makes any difference at all. That being said, it is pretty sleazy that these companies are selling their top tier speakers for thousands of dollars and still using the cheapest materials inside that they can
Sorry, but that ringing in the woofer cone (break up), and smearing caused by cheap parts wasn't what they were shooting for. Those are not house sounds. They are problems not addressed properly.
This really makes you think about all hi end audio products. I'm sure its not just limited to loudspeakers....amps, preamp, integrated amps, etc. If you don't see the "ingredients" which makes the dish, how do you know they're not using the cheapest stuff possible to gain maximum profit possible. There are exceptions I'm sure: Rogue Audio makes exquisite gear for a relative bargain. But it really makes you think...
Who would have thought of from a well-known manufacturer? I guess not everyone is going to open up the box to see if all is good. At $3k you have every right!
He's trying to sell us KITs. We need to have that in mind. if the mid/low woofer should be cut at lower freq, it would have been done already by Dynaudio (it doesn't cost extra money). We can't design speakers on the paper.. But anyway whole topic it's quite interesting.
The point in me doing this isn't to sell upgrade kits. It is to help improve the listening experience for those that have these speakers or any speakers. It also introduces people into the DIY market. And eventually we can step them up into some of our higher quality DIY kits.
@@GRResearch Thanks for response. To dispel all doubts it would be nice to not only see the speakers already equipped with KIT but also to have listen session and a kind of comparison. The point is that I just can't understand how the heck these speakers are so popular, very well rated across the globe while in fact built from shitty parts. I do own a pair of these, I've had compared with many other (even with slightly more expensive ones) before I bought them , and for me there is no better speaker in this price range. I never took a look at the paper, only listen. And of course I know, this is only my personal subjective opinion :)
@@ukaszdubiel7584 No better speakers for the price range? There are way better sounding speakers out there for a fraction of their cost. Our base level X-LS Encore kit at $249 a pair will beat these up pretty well.
@@dannyrichie9743 it sounds so much commercial (KIT again) For me it now seems like there are no any good speakers on the market and we need to get them all equipeed with KITs :) I give up here :) Good luck with your business
@@ukaszdubiel7584 Why not make a speaker better? Any speaker can be tweaked or upgraded. Even our kits come with a list of additional upgrades. That is part of our never ending quest of making our systems sound better and better.
I was looking at these, but I like the sound of the Buchardt 400 MKII better. The Buchardt's are about a $800 to $1,000 less, so I am leaning that way.
I agree the Sony's if you can make them sound great with your upgrade is a greater value than expensive speakers you have to still upgrade. I would consider one of your kits myself
I feel like I'm navigating a minefield in my quest to buy a decent set of speakers! I'm not a wealthy person, so budget is an issue and I don't like the idea of getting scammed when I'm putting together my system.
Strange measurements, as Dynaudio has one of the most advanced measurement systems. These little speakers sound amazing, so how important are the frequency response and the crossover parts if the sound is excellent? I like to see a comparison between the original and the upgraded version, blind tested by an experienced listening panel.
Then they sound have used that measuring system to identify the problems and they should have used some higher quality parts in them for that price point. What they produced is mediocre at best and piss poor for that price point. There is no comparing what they sold to our upgrade.
I don't understand why people talk about "sand cast" resistors. You won't find any "sand cast" resistors in any manufacturer's catalogues. Some resistors are encased in ceramic to aid heat dissipation, but the resistive element doesn't contain any sand. Some ceramic encased resistors are wirewound, and wirewound resistors are very good. How did "sand cast" become a pejorative term?
Linear frequency response is useful in studio, but not at home for enjoying the music. Has this guy ever heard of ear and other human resonances? Nope as i see…
As one of the comment below pointed, it would be damn interesting to have a blind listening test of Dynaudio Special 40s before and after the modifications! It's hard to believe that it would sound better after the intervention without listening to it.. 😅
Hey brother,, I have been mastering for 30 years and recently acquired a set of ATC Scm 12 s. As you said in your last video the atc are good ,, but they need to bring the tweeter up a bit and put some no res inside.. can you send me a kit to do that ,, and how much will it cost?
I was glad to get rid of my Special 40's, I couldn't stand them. Harsh piercing treble, nasally mid range, thin bottom end. Build quality was disappointing and Dynaudio tweeters are notoriously very fragile. I was left bewildered by all the rave reviews, put me off Dynaudio for life. At half the price I much prefer the Monitor Audio Gold 100 5G.
So many here don't get that pretty much any speaker unless you're talking elitsts level and costing speakers. Have relatively cheap crossover parts. Y'all pretend you can hear the difference between a polycap and electrolytic cap with same microfarad values. You don't, it's such a ridiculous claim in general. Don't get me wrong, when you pay a good amount for a speaker. You should expect better parts there I do agree, it adds longevity what not. In the end we use subpar tools (ears) to pretend we understand and can hear perfection. We don't ... So I get that some lovers of these speakers love them, the measurements also don't really apply as people adjust the set up /room to what they wish the hear from it. How many here use diffusion panels? Bass traps (not really a thing trapping bass) but who does it?! Why? If your speakers measure so "perfect" why need all that shit ?! Ohh wait , it depends on the room HOW it sounds ?? See what I am getting at here. Don't get me wrong it's super disappointing to see a brand like that drop the ball like this. But nobody complains about the sound of them... Isn't that what its about. People buy them , and enjoy them no need to banter over a cheap indictor and handful of parts . That in most speaker we own are just as cheesy
He's incorrect about the speaker wiring being coated in PVC.. Dynaudio uses Van Den Hul OFC copper, it's PVC free, double insulated using using HULLIFLEX ® insulation material. Same internal wire used for B&W and other European brands.
Eric is right! I have the SP 40 it‘s van den Hul copper wire. I have the upgrade, it has higher resolution sounds more direct. Not very forgiving any more, now you need good sources and amps!
Disappoints me about dynaudio. I expected a higher quality from this brand. Can you make a sound comparison between the original dynaudio and the dynaudio, but with your improved version?
The Price/Performance ratios for many HiFi speaker manufacturers are ridiciulously bad. Especially crossover design is a weak spot for many, one could almost think they view it as some arcane black magic that needs to be avoided. To be fair many audiophiles believe complex crossovers degrade the sound so manufacturers offer what the customers want.
What a joke - this so-called "expert" has forgotten the golden rule of anything, and everything when it comes to modern technology. Especially when it comes to hifi. So the best analogy would be from a salesman's perspective - sell what it does - not what it is. I bought my Special 40's based on what I heard - and what I heard was good - very good. What the vital ingredient for ALL speakers is to have an amplifier that is compatible. The Dynaudio Special 40's are no exception. So forget about "fancy" upgrade's and the likes - choose your amp well and you'll never look back .
@Car Guy daddyo Some of those high end manufacturers come to be for design work. This model falls far short of the performance level of this price point.
People, they are in an industry where someone can sell you a piece of wire for 4-5 figures that are often rebadged belkins in a fancy jacket or couple pieces of ebony wood that cost pennies for hundreds of $$ b/c people are insecure sheeps that blindly follow the golden eared snake oil pushers/reviewers

I never read anywhere where someone has come forward and modded their speakers and stated it made a vast improvement. These must be all Danny s speakers he's modding.

I've upgraded 3 sets of speakers now with kits from GR, all cheapo no money speakers whose MSRP combined is probably less than 1/6 what this one goes for 😂. But I can say for certain the upgrades make a huge difference. I'm very pleased with how my system sounds and I paid less for a full 5.1.4 system (including GR upgrades on the 5 base level speakers) with receiver (bought broken and fixed) and blu ray player than a friend of mine paid for just one pair of high end KEFs. And I honestly prefer my system over his. Plus I got the fun of working on it myself. 😊
Danny , this is typical for Danish Company or better Scandinavian country , they have a word for it " lagom " it means " good enough ", put money for people eyes then ear, and this modification I am sure it make huge difference in sound quality, I my self works as engineer HW and get tierd of this laziness culture, at work I want do much better but stupid management put finger on it ,. So this is why when you open the box you will see shitty component inside , not quality all through as you expect, unfortunately this engineer culture is on all EU . Greetings from Sweden
Dynaudio was bought by the Chinese. Many Danish companies are surfing on the minimalist heritage and making products that are not worth the price. I’m well placed to talk about this as I worked for one for 19 years!

Pretty good upgrade in terms of measurements. Suprised the woofer measures like that. I'm a huge dynaudio fan, but opening up my sub amp that has failed shows very cheap components just like the cheap crossover components in this speaker. Bit dissapointing to honest.
Thanks, but I'm referring to the actual speakers you are fixing. When you fix the response by redesigning the crossovers, do you hear these differences?
New to the channel... love the videos and the tech talk..... I know your measurements turn out much better but I'm missing the subjective evaluation of "how does it sound". Just because a speaker measures flat doesn't mean it sounds better.
You are correct. The measurements just show if there are audible problems or not. The upgrade in parts quality will make significant improvements in quality across the board.
Danny, i think you should make a complete video starting from your normal analysis, your recommendation then a high quality video of the actual sound before and after the upgrades. This will eliminate any doubt from the viewers. As for me, mostly I agree with you, as i have good result when using a better crossover components.
These videos are very interesting but having heard the Special 40s many times (they sound very good) I have to ask, what's the point of changing all these parts if it doesn't make them sound "better" to the owner? We should all know by now that measurements are not the only determining factor in how well we think a product sounds. Many manufacturers have produced things that measure very well but sound lousy. So I respect Danny's work, it's very important and informative, but without any qualitative listening comparisons before and after it's all moot. The bump in the 1k-1.1k range is well known and many owners of the S40s actually like it, so changing out all the parts for better ones is great in theory but if the sonic signature changes completely or enough that someone who would have bought them might no longer want to, then what's the point. This applies to all these speaker mods, not just the S40s. The HiFi world in general is very out of touch with VALUE, so let's not pretend Dynaudio is ripping people off, almost every audio company is ripping people off. Speakers are $3k, dealer pays ~$1.5k, distributor pays ~$750-$1000, costs Dynaudio maybe $300 to build the pair. That's the whole industry, nothing new there. Companies that sell direct like SVS are better perceived value because they cutout the distribution and dealer networks. They are still making the same profit as all the other companies. Can we get some videos of before an after from people who've done these mods? You can make a nice sauce with a cheap bottle of wine, or a really expensive one, but if the cheap one tastes great, and >%90 of the expensive one which would you choose? The proof is in the pudding as they say.
If you think those sound good, then you haven't heard anything yet. What I did will make them sound better to everyone. You are correct though that the measurements don't tell us how it sounds. The measurements will show if there are or is going to be audible issues. When you do this as often as I do you learn a lot of things that are given. By that I mean something that has repeatable results every time doesn't require confirmation every time to confirm the result. For instance, woofer break up and ringing is not a positive trait. It is not part of the input signal. It is an added coloration and is not desirable. Going from electrolytic caps to good poly caps reduces smearing. Going from cheap poly caps to Sonicaps improved detail levels and clarity considerably. No Rez removes cabinet wall resonances. Tube connectors and better wiring improve clarity every time. I don't need to confirm that every single time. And I get overwhelmingly positive feedback from customers that have implemented our upgrades every single day.
@@dannyrichie9743 that's great, glad people are enjoying the mods. I don't agree with you though about coloration. While in theory it's not desirable, everything we/you do is coloration isn't it? Changing cables, materials, resonance etc. You're just changing the original color to one you prefer. There's no Truth in Hi-Fi though everyone enjoys the journey striving for it. If everything measures the same we'd expect everything to sound the same. Who wants that? Everything can also be improved or humans would have stopped evolving but improvements can be subjective (though not always), especially in Hi-Fi. I prefer more pepper on my steak, my wife prefers salt. Neither one of us is wrong. I think what you're doing is great and very informative, keep it up. Would be great to get input from the manufacturers as to why things were done/left a certain way (aside from cost)? Have you reached out to any of them for comments on your findings and subsequent upgrades?
@@Coolesttech On measuring verses listening. I can make the same two speakers measure exactly the same and sound extremely different depending on the type and quality of parts used. And typically it is not about subjective preference. There are a given set of attributes that are always preferred. For instance, reduced smearing it pretty much always preferred over a smeared sound. And manufacturers reach out to me all the time. I spoke to one this week.
@@Coolesttech It is different with each company. One company sent me a speaker for me to design and offer an upgrade for their customers. One wanted to know how I was measuring and what measuring system I was using. One didn't really care about the upgrades and called to ask me about unrelated design considerations for something new they have in the works. And two of them may be doing a video with me soon. I think we will have Ron and New Record day host a three way video chat with all of us. We'll see.
There is nothing ruined with this upgrade. And a flat response doesn't mean they sound flat. It just means it's accurate. How it sounds has more to do with the parts used and in this case it just got a big upgrade.
Seeing all manufacturers appearing as crapy designers does not provide me with confidence about the one constently doing fingerpointing... There is definitely a common factor here. Wish you all the best.
Building any loudspeaker is all about compromises. I never see in your videos that you measure or addresses Total Harmonic Distortion (at any given freq) and the impact it has on the overall sound, clarity, dispersion and decisions/goal on the final design. Would be great if you could include these measurements and educate your followers accordingly..... Cheers
Hi-Fi such a rip off nowadays. Can’t trust most reviewers either.
Agreed!
KS Digital might be the only brand that i have noticed is actually getting better with each generation. if you want non-rip-off companies to thrive, check em out ksd-audio.de/A-Line/A100/
LOVE it when this guy rips ‘expensive’ speakers.
I would love to see a impulse response in adition to a frequency response. Frequency response is just one side of a coin. I witnessed poor sounding speakers wich had a well balanced frequency response.
Isn't spectral decay similar to impulse response in terms of what we learn from it?
@@PierreVilleneuve88 It is, but impulse response looks at things from a different way, you might be able to see ringing a little better, than the broad overview that a spectral decay offers. Though it can take more work. He's already doing far more than nearly anyone in the industry, so people should cut him slack for the thousands of man hours behind the scene's.
I've used Dynaudio drivers in DIY builds for close to 30 years and I have never seen any of their woofers have a peak like that. Most are very flat over their intended range of use. Not saying your measurements are wrong, just never seen it before. Also Dynaudio cones are not a simple polypropylene.

@jon dough wrong
Truth hurts my man, measurements don't lie, these speakers are junk for 3k, even those cheap Sony's destroy them, especially after his mods. I've seen other people measure these 3k paper weights, nearly the same result...
@@bobking7347 the truth is that dynaudio knows how to make speakers:) junk or not junk depends what kind of sound signature somebody likes
@@MrZenderOne lmao stored energy is not a sound signature
Literally the first time I heard spoken a negative sentence about this speaker. I'll have to be honest, the way I heard it, I liked it. And I think it's generally a bit of a specific taste, upgraded or stock.
Has everyone on here that bashes every brand reviewed ever looked inside the boxes of their electronics or do they also build their own electronics? You're in for a shock if you look inside. Is every kit GR sells beyond reproach or have compromises also been made and further improvements could still be had? Buy what sounds good to you and move on. If the Dynaudios were $2000 would people here be more accepting, not likely, they'd still complain and say they got ripped off. It's hilarious. If you only want to pay the cost of the BOM build your own, I'm sure they'll sound perfect and be super ugly.
There is no such thing as intrinsic value. There is only the value assigned to a product by the purchasers wallet. If these speakers had included all the crossover parts Danny believes they should would anyone who thinks these speakers are a rip off as is suddenly think they're a good deal? Well, if you answered yes you're not thinking clearly. Yes, the crossover parts Danny recommends are more expensive but not even remotely close to being enough to warrant a $3000 price tag based on parts content alone. If you want great overall value from a parts versus performance price then build yourself a kit. Like, seriously, almost any kit. Buy Danny's kit. Buy a kit from Madisound or Parts Express or any of a variety of other sources and you will definitely get more for your money than any commercial speaker will give you. Every product on earth costs more than it's parts content alone and no one man is the absolute arbitor of what those parts should be regardless of price. Are the parts Danny recommends better than what came from the factory? Technically speaking, absolutely. But will changing out the factory parts for the GR-Research parts make this speaker the performance equivalent of a top notch $3000 kit? Not even close! Heck, many people will prefer the sound before the parts change. As I've said before on this channel. It's your money, spend it how you wish. But all anyone can do no matter how skilled they are with speaker design is change, not fix, the sound. The end result of that change may or may not sound better to you. Some people like a bass or midrange bump. Some people like recessed mids or high or even thin bass. Geez, I think some of y'all would sell your house if Danny came along and found that your wall studs, though perfectly safe and installed correctly were southern yellow pine instead of Douglas fir. If it works, you like it and feel it's worth the money, buy it. But If you're buying $3000 bookshelf speakers in the first place, well, I'd say that no matter how good the parts are inside, your perception of value is too skewed to worry about anyway!
Amen
When you spend the money you also invest in a company. The level of components you get for your money is only a fraction of the value you get in return.
If you want the manufacturer to pay salaries, rent office space, do research and development etc then you assume your 3k isn't getting you 3k in parts. The product you receive is only a fraction of that. If it weren't, there would be no company to buy speakers from
PERFECTLY SAID.
I am kind of confused after 30 years of Hifi and DIY speaker building looking at all your videos. Seems you think to increase sound of every commercial speaker by flattening the frequency response on axis and 30°. But is it that easy? To be honest: I did not hear any of your own speakers or any speakers modified by you. But I am kind of struggeling to believe becuase from my experience the big companies like Dynaudio know very well about speaker sound refinement.
What about impulse response or THD in higher power levels? I cannot believe changing poly caps to more expensive poly caps and corretly rated iron inductors changing to air inductors change the world. (and I have changed many poly caps in my live)
From my opinion it is more the developer feeling to understand how to adjust the crossover to get the speaker sound good. And I believe that Dynaudio for sure recruted the best developers for the job.
Hi GR-Research, please give me a response so that I can understand it. I am at least not a complete noop , german diploma in electric engineering since 19 years. so I think I should potentially be capable to understand what you would explain.
@Thorsten Hoffmann Give him a phone call, I called him once because I was having trouble ordering no-rez product on his website. He was nice and helpful. However, I wouldn't expect him to have a long conversation, he's busy running his company.
Interesting video. Measurements are interesting for sure but most important is how they sound and it is not necessary the same as how they measure.
They sound even better than the measured improvements.
True.
This chap still believes into significant differences between cables, capacitors and coils. I tried this in the 1980's (young ears) several times without result. Useless approach, except for the providers of such parts. Buy better speakers, if you are not happy, and please do not waste money on esoteric nonsense!
While I agree that changes in some of those will not alter the audio signature, he does show actual improvements in objective measurements from the upgrades. Regardless, he's right in that for that $, it should not be full of low grade parts. That brand seems a terrible value for $.
Ok boomer
@@willbrink Sorry mate, but he is straight up lying to you and then you repeat it.
1) He did not fix anything - all he did is change the frequency response - which he can do, but that does not make the speaker better just because it is flatter.
2) Dynaudio is one of the best known brands for their high quality speakers with top notch parts. That is the reason why a pair of Focus 340 I bought used 5 years ago 2.000€ are still worth that money now.
3) This has nothing to do with dollers - these aren't your typical cheaply made American speakers - these are done by engineers from Denmark.

A: Of course has to do with dollars, and some companies charge a fair price for they offer, some, not so much.

As far "done by engineers from Denmark" you're poorly informed: "Dynaudio is a chinese company with a chinese majority owner. Some of the lower lines are FULLY MADE IN CHINA. The cabinets are outsourced, and the higher lines are assembled in Denmark." Dynaudio was acquired by Goertek in 2014

I've had the Dynaudio Special 40s for about 3 years now, driving them with a NAD C-390DD and they sound incredible. Absolutely incredible. And I listen to a lot of speakers in that price range and higher before I purchased. I understand the measurements but I'll trust my ears and the ears of many reviewers and users who also love them.
If you liked them stock then you'll really like them after the upgrade. I guarantee you, I can make you love them a whole lot more.
I would believe Danny's response!
Enjoy the speakers as they are. Mod them and they become worthless. let the bullshit start....
@@ej20tscully Actually they will have more value after the mod.
I’ve had mine for a few months now and also love the sound of them...
If you ever get a Dynaudio Heritage Special in your workshop and it goes in somewhat the same direction as the S40 then i'll be damned!
You can see that the quality of components used in the Heritage is far higher as it should be for the price. This kit will bring you close to the Heritage for a few hundred.
This seems like a man who is just trying to sell his crossover kit. It doesn’t really matter how they measure on paper, it matters how they sound. That’s what you’re paying for. And these speakers sound pretty damn amazing and are worth every penny.

LOL.
The fact that you even tried to compare Sony with a brand like Dynaudio just shows that you have absolutely no clue what a good speaker sounds like. Maybe you should get your hearing checked. I also use to work in sales myself, so I know the tactics that a salesman uses.

No need to have my hearing checked either. Anyone that is not deaf can hear the improvements this upgrade offers.

Sold! - UPDATE - I bought this upgrade. It's easy to install, even for a complete novice. The sound is much clearer and more engaging now. Transients are faster with much more impact. I was actually startled at one point. Female vocalists like Mary Chapin Carpenter now have a lifelike breathy quality and the soundstage is way more open. This is the kind of upgrade I would expect from buying the Special Heritage which cost $7K (co-incidentally, that has similar quality parts to what GR Research offer for a few hundred dollars). Try it and be amazed.
@@blue-ck9ns People are not worried about their warranty. They want the high quality performance that they thought they would get when they bought these.
I believe these speakers were supposed to be "fun" and were voiced accordingly. Dynaudio certainly has a house sound, much like Harbeth or Sonus Faber, etc. that you either like or don't like. Fixing the cabinet resonance and flattening the curve (especially without consideration of the speaker's polar response or the room) is counterproductive and will absolutely ruin the resale value. If you want a "neutral" sounding monitor you should just purchase one to begin with.
Actually, the polar response has been improved as well. Also, only part of the upgrade is balancing out the response. That nasty woofer resonance is not part of a house sound either. They just neglected to correct it, and it needed correcting. These were also being held back by the parts quality. The upgrade is a transformation from a lifeless and problematic speaker into a pretty decent speaker.
I dont care how they meassure..I care about how they sound..and I think they sound pretty damn good...

@@murcielago188 well if they sound great...they sound great...so no not really..

@@jespergth9437 Then i appoligize. But surely you get my drift about spending a relatively small percentage of a speaker's $3000 price to flatten-out such a lumpy & hence "unfaithful to whatever the source's" intended frequency reproduction, of course we don't always get a chance to know of such a potential 'massive' improvement for every potential speaker purchase, but if i'd bought this particular model, because it sounded good in the 1'st place, then after seeing this vid i'd be ultra-keen to take the extra monetary step to extract the best out of it, especially after seeing the before & after graphs showing the magnitude of difference this upgrade made. if it was my main hi-fi listening source, which any $3000 speaker would have to be (in my wealth bracket, or lack of)
Good luck
@@The-Spotlight-Kid not so sure about if the "new parts" actually make it sound better. i dont think its that simple. Those "high qualiity" parts might completely destrpy they sound of those speakers. GR-Research is in the business of selling upgrade kits. OFC they claim that simply changing part to another will improve the sound. or changing graph will improve the sound... afaik, its not that simple and straightforward. if it was, most hifi companies would use those parts.
Spending 3 grand on a pair of speakers, you shouldn't have to spend another $300 dollars to make them sound better, it should be done at the factory where they are made
You’ve just lowered their sensitivity and power handling. That poor tweeter is going to be compressed sounding.
Could you post the music sample clips before and after, so we could get a sense to what degree the sound improvement is.
I really would like an actual listening test before and after, just like how cables should be treated. Nothing against measurements, but listening is the real test. At least in my opinion.
That's the thing I feel is missing from the content on this channel. Measurements are great but speakers are made to sound appealing, and measurements are only one part of this.

Funny guy 😄😄
Well, to me the FR plot after the “upgrade” looks worse than the original on some frequencies, while he flattened a bit the 1K region he also created a deeper valley on the 6K region, also I don’t buy the individual “woofer measurements”, since the woofer has been tweaked to work along with the original crossover, what I would ONLY do is replacing the inexpensive parts in the crossover with higher quality parts but keeping the original values.
My point is actually a bit different - I'm not so sure the tweeter is able to handle low x-o freq proposed in the upgrade. While the bump in midwoofer freq response looks terrible, most 6" drivers have the cone edge artifact. To me the crossover could be optimized better from the factory, but I wouldn't cut the tweeter so low unless I'm 100% certain it can take the extra signal without introducing it's own distortions. Actually I have nothing against the original voicing of this speaker.
The drivers are just pulled of a shelf and the crossover and box is designed to suit. They basically only make 1 bass/mid driver, in various sizes. They all have the same motor, the same cone material and basically the exact same T/S parameters apart from the sensitivity, resonant frequency and overall bandwidth.
So any speaker they make using this driver with the 3 inch coil is going to have the exact same issue. Even the cars like VW that have these drivers just with a plastic basket I bet have the exact same issue, unless its caused by the basket but the frequency is way to high to be caused by solid cast alloy
The thing is that I don’t get why the original crossover has to be flawed, every hi-fi loudspeaker on the market has its signature sound, if you want a flatter FR go get studio monitors period, I myself own the S40’s, I can tell you that with the right electronics and the right placement these loudspeakers sound very life-like and sweet, I really like them, are there better loudspeakers?, of course there are, but at this price point these loudspeakers are very, very, very good at soundstage, dynamics and detail, besides that there’s no “perfect” speakers on the market, they all have colorations and distortion.
I think you are asking "why is the shape of the response a flaw and not a feature"? Well, I guess you could look at it that way. A song should be recorded perfectly, and a speakers job is to play the song back with nothing added or taken away. The speaker should never be able to make a song sound "better", only worse. A speaker that doesn't not play like a flat studio monitor is adding peaks and distortion information that should not be there, or it is taking away info that should be there. As I said, the song should be recorded perfectly so that when it is played back 1:1 with a flat playing speaker it sounds the best.
I think there is a misunderstanding about hi-fi loudspeakers and studio monitors loudspeakers, hi-fi speakers usually have some pleasant colorations, they could be on the neutral side of warm or they can be a bit bright, some others can have a slight V shaped sound, so a flat FR in hi-fi speakers is not always a desirable feature, in fact is not expected, this is what audiophiles are looking for, some audiophiles find flat FR speakers boring and uninvolving, but a flat FR is desirable for studio monitors. The S40’s are considered a balance sound loudspeakers with a touch of warmth and air at the top. This is why I find this kind of crossover “correction” completely pointless.
this is a guy who listens to numbers. really really. boring style of speaking, too.

it would be a good move, depending on the distance and time invovlved. Just trust this man he is very skilled I know.
Agreed! Maybe Danny could try to work out a post-upgrade interview or follow-up?
There's a good possibility they are still trying to notice the deference and were there money went
We'll see or hear from them soon. I have already sold six of these upgrades.
Would be great if this "expert" did some fact checking before posting this video, but maybe that's too much to expect!
Speaker cable inside Special 40 is NOT cheap! It is VanDenHul The Snowline.
Non-electrolytic capacitors are Mundorf capacitors.
I don't think that was what was in these speakers.
But the fact there are electrolytic caps in there is a joke...
@@dannyrichie9743 l’m with YOU, Danny.
Dynaudio does use Mundorf in some of their higher end speakers. However these are probably Bennic. My Dyn 52se's have Bennic I believe. I took a peek in there.
Obviously you didn't read the full review by stereophile and they know what their listening to after comparing speakers over the last 30 plus years. Do you listen to the speakers before you mod them for your own profit.
I don't have to read what someone else thinks to see what's wrong with them. And John Atkinsons measurements looked a lot like mine. He also commented on the woofer break up at 1.1kHz and the cabinet wall resonances. And yes, I've heard these speakers before.
Disapoonting. I expected more from Dynaudio.
time and time again, what one is really buying when they go up the line, is a furniture grade enclosure. thats 90 % of the cost. rarely, if ever, do they use true audiophile parts internally, even with exceptional drivers. to some degree, one is buying a "conversation" piece for their home , and with it high WAF:
Well, Dynaudio was acquired by a large Chinese consortium in 2015 or so. When that happens, expect everything you know from your favourite brand to go to s***.
What's the issue with PVC coat?
It's kind of the heaviest, with bad numbers. It completely changes the signal speed in the cable. Lightest is the best, with air inside,. Best is air, bur technically difficult. Some high-end even goes for cotton, yep grandma's underware cotton, like Duelund.
Do people pay all that money to have to upgrade them,seems to me they did not bother to really listen to them in the first place!!!
Its funny how Danny thinks he does a better job with Windows XP vs Dynaudio’s measuring facility
Sad but true and very obvious. They are also no longer designed in some facility in Denmark. They are owned by a China based company and assembled there as well.

Good question!
It's a hot steamy one that......
Instead or me telling you what I think, let's wait and hear from everyone implementing the kit.
@@dannyrichie9743 That's a bit of a cop out!
@Yael Jerome I thought it took only 15 minutes?
The special 40 are superb speakers. Don't ruin them.
The problem with 'upgrading' crossovers like this, is the assumption that perfectly flat is the best way a speaker could measure. What makes a dynaudio sound different from a KEF or a Focal speaker in large part is those little peaks and valleys through the EQ range which either accentuate or soften certain frequencies. Making it flatter isn't inherently better, it's just different. As far as wiring quality, etc. it's been pretty well disproven that that stuff makes any difference at all. That being said, it is pretty sleazy that these companies are selling their top tier speakers for thousands of dollars and still using the cheapest materials inside that they can
Sorry, but that ringing in the woofer cone (break up), and smearing caused by cheap parts wasn't what they were shooting for. Those are not house sounds. They are problems not addressed properly.
Oh ,let me guess....you could build a better one ffs
This really makes you think about all hi end audio products. I'm sure its not just limited to loudspeakers....amps, preamp, integrated amps, etc. If you don't see the "ingredients" which makes the dish, how do you know they're not using the cheapest stuff possible to gain maximum profit possible. There are exceptions I'm sure: Rogue Audio makes exquisite gear for a relative bargain. But it really makes you think...
Absolutely crazy a speaker manufacturer would charge so much for cheap parts.
Who would have thought of from a well-known manufacturer? I guess not everyone is going to open up the box to see if all is good. At $3k you have every right!
He's trying to sell us KITs. We need to have that in mind.
if the mid/low woofer should be cut at lower freq, it would have been done already by Dynaudio (it doesn't cost extra money).
We can't design speakers on the paper..
But anyway whole topic it's quite interesting.
The point in me doing this isn't to sell upgrade kits. It is to help improve the listening experience for those that have these speakers or any speakers. It also introduces people into the DIY market. And eventually we can step them up into some of our higher quality DIY kits.
@@GRResearch Thanks for response. To dispel all doubts it would be nice to not only see the speakers already equipped with KIT but also to have listen session and a kind of comparison.
The point is that I just can't understand how the heck these speakers are so popular, very well rated across the globe while in fact built from shitty parts. I do own a pair of these, I've had compared with many other (even with slightly more expensive ones) before I bought them , and for me there is no better speaker in this price range. I never took a look at the paper, only listen. And of course I know, this is only my personal subjective opinion :)
@@ukaszdubiel7584 No better speakers for the price range? There are way better sounding speakers out there for a fraction of their cost. Our base level X-LS Encore kit at $249 a pair will beat these up pretty well.
@@dannyrichie9743 it sounds so much commercial (KIT again)
For me it now seems like there are no any good speakers on the market and we need to get them all equipeed with KITs :)
I give up here :)
Good luck with your business
@@ukaszdubiel7584 Why not make a speaker better? Any speaker can be tweaked or upgraded. Even our kits come with a list of additional upgrades. That is part of our never ending quest of making our systems sound better and better.
I was looking at these, but I like the sound of the Buchardt 400 MKII better. The Buchardt's are about a $800 to $1,000 less, so I am leaning that way.
The Buchardt's are better speakers by far.
I agree the Sony's if you can make them sound great with your upgrade is a greater value than expensive speakers you have to still upgrade.
I would consider one of your kits myself
Mdf is very dense and that’s why speaker manufacturers use it. These are good sounding speakers. A little colored but good sounding.
100% more than good. Excellent.
Why would Dynaudio sell these speakers with a not so good crossover? This speaker is not cheap!
I feel like I'm navigating a minefield in my quest to buy a decent set of speakers! I'm not a wealthy person, so budget is an issue and I don't like the idea of getting scammed when I'm putting together my system.
I love how you say your going to" throw in" a sheet of no-rez, as if it was free, but then the price jumps up one more time.
I think the jump was the labour charge not the no-res
@@chrisburn7178 There is no labor, he's selling a bag of parts.
IMO over priced bookshelf.
That’s a lot of money for a beautiful “piano grade” finish. I’d rather buy the piano. 😉
Heck yea... still building my subs but just a bit here and I’ll have THE BEST subwoofer setup under 5k ! Excited
There must be big margins for all sellers in the supply chain for upmarket speakers!
Strange measurements, as Dynaudio has one of the most advanced measurement systems. These little speakers sound amazing, so how important are the frequency response and the crossover parts if the sound is excellent? I like to see a comparison between the original and the upgraded version, blind tested by an experienced listening panel.
Then they sound have used that measuring system to identify the problems and they should have used some higher quality parts in them for that price point. What they produced is mediocre at best and piss poor for that price point.
There is no comparing what they sold to our upgrade.
Why dont you like PVC insulation?
What audio degradation do you attribute to PVC?
I don't. It does not sound good.
Heritage Special please!
Let’s not forget that Dynaudio was bought by the Chinese. It has now been rated as a damn awful place to work by ex-employees !
How long ago? This design is getting long in the tooth
@@billd9667 I was in told by a Danish friend very recently. I can’t answer that
The only thing made well in China are
..................... Dumplings...............
You're right, I see on Wikipedia, in 2014 Dynaudio was bought by the Chinese company Goertek Inc.
I heard your wife is cheating on you as well, but just like you I can’t say who told me. Real credible.
I don't understand why people talk about "sand cast" resistors. You won't find any "sand cast" resistors in any manufacturer's catalogues. Some resistors are encased in ceramic to aid heat dissipation, but the resistive element doesn't contain any sand. Some ceramic encased resistors are wirewound, and wirewound resistors are very good.
How did "sand cast" become a pejorative term?
The term sand cast is how the ceramic shell is cast. There is no sand in the electrical path.
Linear frequency response is useful in studio, but not at home for enjoying the music. Has this guy ever heard of ear and other human resonances? Nope as i see…
As one of the comment below pointed, it would be damn interesting to have a blind listening test of Dynaudio Special 40s before and after the modifications! It's hard to believe that it would sound better after the intervention without listening to it.. 😅
Hey brother,, I have been mastering for 30 years and recently acquired a set of ATC Scm 12 s. As you said in your last video the atc are good ,, but they need to bring the tweeter up a bit and put some no res inside.. can you send me a kit to do that ,, and how much will it cost?
I was glad to get rid of my Special 40's, I couldn't stand them. Harsh piercing treble, nasally mid range, thin bottom end. Build quality was disappointing and Dynaudio tweeters are notoriously very fragile. I was left bewildered by all the rave reviews, put me off Dynaudio for life. At half the price I much prefer the Monitor Audio Gold 100 5G.
So many here don't get that pretty much any speaker unless you're talking elitsts level and costing speakers. Have relatively cheap crossover parts. Y'all pretend you can hear the difference between a polycap and electrolytic cap with same microfarad values.
You don't, it's such a ridiculous claim in general. Don't get me wrong, when you pay a good amount for a speaker. You should expect better parts there I do agree, it adds longevity what not.
In the end we use subpar tools (ears) to pretend we understand and can hear perfection. We don't ...
So I get that some lovers of these speakers love them, the measurements also don't really apply as people adjust the set up /room to what they wish the hear from it.
How many here use diffusion panels? Bass traps (not really a thing trapping bass) but who does it?!
Why? If your speakers measure so "perfect" why need all that shit ?! Ohh wait , it depends on the room HOW it sounds ?? See what I am getting at here.
Don't get me wrong it's super disappointing to see a brand like that drop the ball like this. But nobody complains about the sound of them... Isn't that what its about. People buy them , and enjoy them no need to banter over a cheap indictor and handful of parts . That in most speaker we own are just as cheesy
Can you do a kef ls50 meta?
Yes! I am very curious if Kef changed the crossover of the new LS50 Meta.
He's incorrect about the speaker wiring being coated in PVC.. Dynaudio uses Van Den Hul OFC copper, it's PVC free, double insulated using using HULLIFLEX ® insulation material. Same internal wire used for B&W and other European brands.
It did not look that way to me.
Eric is right! I have the SP 40 it‘s van den Hul copper wire. I have the upgrade, it has higher resolution sounds more direct. Not very forgiving any more, now you need good sources and amps!
Would love to see you take apart some of those overpriced 50k speakers that are out there.
Hey gr research what about monitor audio gold 100 5g or 7g are they better than dynaudio s40
Great video!!
Nice msg on ur t-shirt 👌
Disappoints me about dynaudio. I expected a higher quality from this brand. Can you make a sound comparison between the original dynaudio and the dynaudio, but with your improved version?
How embarrassing for Dynaudio.
Interested in how the Heritage models measure and what the quality of parts is, speaker companies make a living from ripping you off.
Dynaudio uses Mundorf caps in their some modeks of their Contour and Confidence lines according the website.
Any upgrades for the Emit 20 speaker?
The Price/Performance ratios for many HiFi speaker manufacturers are ridiciulously bad.
Especially crossover design is a weak spot for many, one could almost think they view it as some arcane black magic that needs to be avoided.
To be fair many audiophiles believe complex crossovers degrade the sound so manufacturers offer what the customers want.
I belive that the new crossover frequency at 1.3 - 1.4khz i a bit to low for the tweeter to handle.
Not at all. The steepness of the filter protects it just fine.
What a joke - this so-called "expert" has forgotten the golden rule of anything, and everything when it comes to modern technology. Especially when it comes to hifi. So the best analogy would be from a salesman's perspective - sell what it does - not what it is. I bought my Special 40's based on what I heard - and what I heard was good - very good. What the vital ingredient for ALL speakers is to have an amplifier that is compatible. The Dynaudio Special 40's are no exception. So forget about "fancy" upgrade's and the likes - choose your amp well and you'll never look back .
No amplifier is going to fix the problems with that speaker.
@Car Guy daddyo Some of those high end manufacturers come to be for design work. This model falls far short of the performance level of this price point.
Kinda scary what these manufacturers can sneak by the buyer
The most important thing is do you like the sound?
Exactly.
People, they are in an industry where someone can sell you a piece of wire for 4-5 figures that are often rebadged belkins in a fancy jacket or couple pieces of ebony wood that cost pennies for hundreds of $$ b/c people are insecure sheeps that blindly follow the golden eared snake oil pushers/reviewers

I never read anywhere where someone has come forward and modded their speakers and stated it made a vast improvement. These must be all Danny s speakers he's modding.
Read more of the responses to our videos and post on our forum and elsewhere all over the Internet. Not only do the customer love the vast improvement. They become repeat customers.
I've upgraded 3 sets of speakers now with kits from GR, all cheapo no money speakers whose MSRP combined is probably less than 1/6 what this one goes for 😂. But I can say for certain the upgrades make a huge difference.
I'm very pleased with how my system sounds and I paid less for a full 5.1.4 system (including GR upgrades on the 5 base level speakers) with receiver (bought broken and fixed) and blu ray player than a friend of mine paid for just one pair of high end KEFs. And I honestly prefer my system over his. Plus I got the fun of working on it myself. 😊
Hi Danny, great video! How to test some Wharfedales, Evo series? I would appreciate if you could!
Has anyone compared a modded pair to a standard pair? What happens to the sound?
Danny , this is typical for Danish Company or better Scandinavian country , they have a word for it " lagom " it means " good enough ", put money for people eyes then ear, and this modification I am sure it make huge difference in sound quality, I my self works as engineer HW and get tierd of this laziness culture, at work I want do much better but stupid management put finger on it ,.
So this is why when you open the box you will see shitty component inside , not quality all through as you expect, unfortunately this engineer culture is on all EU .

You might want to do some more listening. There is a whole new world out there.
Pretty good upgrade in terms of measurements. Suprised the woofer measures like that. I'm a huge dynaudio fan, but opening up my sub amp that has failed shows very cheap components just like the cheap crossover components in this speaker. Bit dissapointing to honest.
why speaker is so expensive danes don t lie, or danes steal ?
Do you ever listen to these speakers before and after your mods or do you just measure them?
A lot of time is spent comparing and listening to the differences in the parts.
Thanks, but I'm referring to the actual speakers you are fixing. When you fix the response by redesigning the crossovers, do you hear these differences?
I would like to borrow your question to ask dynaudio
@@ok4486 It doesn't look like they even measure their speakers.
I bought this kit and the speakers are way better afterward. Clarity, dynamics and musical enjoyment are far higher.
New to the channel... love the videos and the tech talk..... I know your measurements turn out much better but I'm missing the subjective evaluation of "how does it sound". Just because a speaker measures flat doesn't mean it sounds better.
You are correct. The measurements just show if there are audible problems or not. The upgrade in parts quality will make significant improvements in quality across the board.
Danny, i think you should make a complete video starting from your normal analysis, your recommendation then a high quality video of the actual sound before and after the upgrades. This will eliminate any doubt from the viewers. As for me, mostly I agree with you, as i have good result when using a better crossover components.

@@rondegroot1508 lol
These videos are very interesting but having heard the Special 40s many times (they sound very good) I have to ask, what's the point of changing all these parts if it doesn't make them sound "better" to the owner? We should all know by now that measurements are not the only determining factor in how well we think a product sounds. Many manufacturers have produced things that measure very well but sound lousy. So I respect Danny's work, it's very important and informative, but without any qualitative listening comparisons before and after it's all moot. The bump in the 1k-1.1k range is well known and many owners of the S40s actually like it, so changing out all the parts for better ones is great in theory but if the sonic signature changes completely or enough that someone who would have bought them might no longer want to, then what's the point. This applies to all these speaker mods, not just the S40s. The HiFi world in general is very out of touch with VALUE, so let's not pretend Dynaudio is ripping people off, almost every audio company is ripping people off. Speakers are $3k, dealer pays ~$1.5k, distributor pays ~$750-$1000, costs Dynaudio maybe $300 to build the pair. That's the whole industry, nothing new there. Companies that sell direct like SVS are better perceived value because they cutout the distribution and dealer networks. They are still making the same profit as all the other companies. Can we get some videos of before an after from people who've done these mods? You can make a nice sauce with a cheap bottle of wine, or a really expensive one, but if the cheap one tastes great, and >%90 of the expensive one which would you choose? The proof is in the pudding as they say.
If you think those sound good, then you haven't heard anything yet. What I did will make them sound better to everyone.
You are correct though that the measurements don't tell us how it sounds. The measurements will show if there are or is going to be audible issues.
When you do this as often as I do you learn a lot of things that are given. By that I mean something that has repeatable results every time doesn't require confirmation every time to confirm the result. For instance, woofer break up and ringing is not a positive trait. It is not part of the input signal. It is an added coloration and is not desirable. Going from electrolytic caps to good poly caps reduces smearing. Going from cheap poly caps to Sonicaps improved detail levels and clarity considerably. No Rez removes cabinet wall resonances. Tube connectors and better wiring improve clarity every time. I don't need to confirm that every single time.
And I get overwhelmingly positive feedback from customers that have implemented our upgrades every single day.
@@dannyrichie9743 that's great, glad people are enjoying the mods. I don't agree with you though about coloration. While in theory it's not desirable, everything we/you do is coloration isn't it? Changing cables, materials, resonance etc. You're just changing the original color to one you prefer. There's no Truth in Hi-Fi though everyone enjoys the journey striving for it. If everything measures the same we'd expect everything to sound the same. Who wants that? Everything can also be improved or humans would have stopped evolving but improvements can be subjective (though not always), especially in Hi-Fi. I prefer more pepper on my steak, my wife prefers salt. Neither one of us is wrong. I think what you're doing is great and very informative, keep it up. Would be great to get input from the manufacturers as to why things were done/left a certain way (aside from cost)? Have you reached out to any of them for comments on your findings and subsequent upgrades?
@@Coolesttech On measuring verses listening. I can make the same two speakers measure exactly the same and sound extremely different depending on the type and quality of parts used.
And typically it is not about subjective preference. There are a given set of attributes that are always preferred. For instance, reduced smearing it pretty much always preferred over a smeared sound.
And manufacturers reach out to me all the time. I spoke to one this week.
@@dannyrichie9743 and what are they telling you? Are they disputing your findings or justifying them or both?
@@Coolesttech It is different with each company. One company sent me a speaker for me to design and offer an upgrade for their customers. One wanted to know how I was measuring and what measuring system I was using. One didn't really care about the upgrades and called to ask me about unrelated design considerations for something new they have in the works. And two of them may be doing a video with me soon. I think we will have Ron and New Record day host a three way video chat with all of us. We'll see.
I wonder if these new improvements ruined it's special sound? Flat isn't always better or we would all listen to studio monitors.
There is nothing ruined with this upgrade. And a flat response doesn't mean they sound flat. It just means it's accurate. How it sounds has more to do with the parts used and in this case it just got a big upgrade.
Seeing all manufacturers appearing as crapy designers does not provide me with confidence about the one constently doing fingerpointing... There is definitely a common factor here. Wish you all the best.
This guy gets it.👍
Building any loudspeaker is all about compromises. I never see in your videos that you measure or addresses Total Harmonic Distortion (at any given freq) and the impact it has on the overall sound, clarity, dispersion and decisions/goal on the final design.
Would be great if you could include these measurements and educate your followers accordingly..... Cheers
