It's approx $500 to build a pair (so $250 per speaker), which is good value when you think that a Sonos or Bose will set you back at least that much only instead of getting a single unit you get a stereo pair with better audio quality to boot!

TWEETERS are optional, as the midtone driver + DSP sounds great on its own, but for the best quality a good budget tweeter is the SB Acoustics SB26STCN, which is my favourite overall due to its pricing, but a premium option is a Scanspeak D2608/913000 Tweeter. It has a bit more ‘sparkle’ and refinement, but this will ONLY be appreciated if the final speakers are given a signal from a high-quality output source like a dedicated DAC.
If you want to print the baffles, the recommended magnet size is 10mm diameter round neodymium magnets, with 5mm depth maximum.
Fixtures and fittings:
40pcs M3 threaded inserts (for the speaker drivers)
40pcs 3mm x 8mm countersunk m3 black screws (for the speaker drivers)
200pcs Self-tapping 2mm diameter screws, 10mm length max (build platform screws)
24pcs 3mm diameter self-tapping screws (amplifier screws, DSP chamber, midtone chamber base)
2x step-down voltage regulators, 5v output (for powering the DSP and fan)
2x 1000uf capacitor (add across the output of the regulator to reduce interference)
2x Power Adapters (100w ideally, each. A low cost option is old laptop power adapters)
1x roll of 16awg wire
Recommended glue is CT1 - it sticks to PLA well enough and doesn't set too quickly allowing the whole speaker to be screwed together before it begins to dry. This allows any spill over to be wiped away (use an old brush to get inside the air guide etc). Sets with some amout of flexibility. Readily availabe in the UK but not sure about equivalents for other territories. Visit the Forum or Discord server to see what the community recommends for each region.
SAFETY NOTES ON PLASTER OF PARIS: If you're stupid with it, it can be dangerous. NEVER put your hands/feet/whatever into plaster of paris EVER. It can suddenly set without warning, creating a lot of heat in the center, so you'll get burned or worse. Because of this never leave a batch of wet plaster of paris in reach of children or pets. Wearing a mask is recommended to not breathe in any dust, and goggles to stop it splashing into your eyes. Stay safe people! - วิทยาศาสตร์และเทคโนโลยี
This project required a LOT of research and development but the sound quality is so worth it! 🔊🤩Don't forget that if you want to build a pair yourself you can buy the files for it here: payhip.com/b/dhJrS

Hi
you forgot to take edge refraction into account.

This guy is on another level... The amount of effort that he puts on every video is just amazing!
1:34, yeah and unlike Linus, he doesn't drop things. 🤣
He is a smart dude and he must be making serious bank running pretty much solo with that many subs. Totally deserves everything he's worked for. :)
@@Cyba_IT yup
This is why you never fret about how much time goes between his videos. You do however get happy when they are released, because you know they are a level above all the 'other stuff'.

Dude, this is probably the most advanced "I teach people how to build something useful" video that has ever been uploaded to youtube. Amazing stuff!
I wonder if someone actually has done something he shows, haha
@@TheKitMurkit was literally thinking the same ha
Not at all. All he does is provide the plans for one particular design, and demonstrate how to assemble it. After watching this video, you're still no closer to understanding how to build decent speakers. All you have are design files for one particular model, which you can print out and assemble at home.
Not that I'm dissing the video. But saying it's "the most advanced video teaching people to build something useful" is a long stretch. Hyperbole notwithstanding (have you actually watched each and every tutorial on TH-cam to confidently make that assessment?), there are other videos of his more worthy of that description.
@@EvenTheDogAgrees I was thinking of that too.
@@EvenTheDogAgrees Did we watch the same video or do you just need your hand held for everything?
I am blown away! As a maker, a tinkerer, a DIYer, a music lover, and an audiophile, I am flabbergasted by the level of detail, quality, and professionalism displayed by this speaker build. Outrageous!
You should build them then. I did, they're not worth the $ and effort.
@@cheregimihai Did you buy the exact same DSP? I am just wondering how to connect the wires for the output and input if I want stereo input and output.
Some brits are truly overtalented and not from this planet. Im one hundred percent sure that few brits like clapton or blackmore are aliens.
@@cheregimihai are they worth the $? these are design for people that enjoy DIY and the effort = joy
by the measurements he show they are worth, but doing DIY has the downsides of using different materials, bad gaps, and is easy to end up with different results.
he"s doing his homework & research , obviouvsly ....
The fact that this is a project genuinely meant to be done by the viewer of the video, with just a 3D printer, some plaster, and basic tech savviness is absolutely amazing.
Thank you for your hard work 👍
“Just a 3-D printer”…🙄
@@terryjones573theyre like $200 new and undiscounted, can be down to $70 used. I got mine for $150 new during a didcount. A $200 tool that offers the kind of flexibility that a 3d printer can do isn’t that crazy. Its the same amount that you spend on a basic set of car tools, yet nobody seems to be complaining about the entry cost of doing your own oil changes.
@@terryjones573A 3d printer costs less than a manufactured comparable speaker and can be used for more than just this project... 🙄
@@brayden5676 With the assumption being that everyone can/will/wants to find even more projects to do to make up the cost. And I don’t know if I believe that.
@terryjones573 They'd make up the cost on just making a pair of these speakers if you were to compare these to an equally-sounding pair of speakers. Amateur hobby 3d printers aren't that expensive, you could easily get a solid one for $250-$300. It'd be like needing some power tools for a project that you'd save $500 bucks on by doing it yourself vs paying someone else to do it
This channel consistently toes the line for high quality video/audio editing and polished dialogue. The lower frequency of video releases affirms that excellent content requires *extensive* time to produce, and they are always worth the wait. Matt's videos show why watching #shorts is a waste of your valuable time.
Agreed. Every time I see an upload here I know it's about to be some next level stuff and it never disappoints. This isn't just "I built a DIY speaker" it's always "I built a speaker that probably kicks the ass of most things you can buy on the market unless you want to go broke buying it"

Most of what you say is true, but there is a lot of well made short form content out there
@@romella_karmey bro will simply invent a quantum smartphone as his next DIY project
I love these sound projects! I have a feeling that some day, he will make a design which sounds so good he could chose to start his own hifi brand and print,build and sell his speakers on the hifi market!
As a HiFi lover and DYI guy, I am absolutely marking this video as one of the best things I have ever seen on TH-cam. It basically explains the design most companies go through to put out a product nowadays, but you can do your own at home if you have the time, skill and patience. Remember, the fact that you can customize your DSP means you can give it a different sound profile if you choose something else than flat. You could also slightly tweak things around to be able to fit other amps (within reason), meaning you could have the perfect speakers to last a really long time. Absolutely incredible.
DSP isn't the answer. There are dotted lines and arrows and circles. The sky is a chart that explains the entire world. But you can’t see it. I know that.
0:13 simple boxes not gonna cut it? wtf just buy a refurbished pair of 80's high or mid high quality wooden speakers where the box size is min 50cm. they sound better than any of this overengineered and overpriced crap they make today lol. and sound bars??? lol.
Do you have a TH-cam channel also.
@@uiopuiop3472 reported as spam
@@kbuss10 No, just no. Around 500$ will give you excellent sound if you know what to look out for. Add to that another 500 for subwoofers and you've got a very good sound system for 1k$ including amplifiers. But seems you only shop at large retail stores where they actually sell the crap you speak of. Though I would not call that overengineered as it's usually the same 2.5-way dome-woofer-setup over and over again.
I just finished building a pair of these. For someone that is typically very handy and loves a project, yet has zero audio knowledge, I was able to walk away with a very pleasing result. I finished mine with walnut veneer on the sides and rose copper chrome on the front. A bit of feedback that I would have valued would have been to include a more detailed step-by-step in your instructions than what is currently available. I found myself having to figure a lot of things out for myself. Again... I am a total newcomer to audio and its equipment so maybe im in the minority for this
Thank you for the extremely fun and rewarding project. Looking forward to tackling something from you in the future :D
Was there detailed instructions on how to wire everything and tune the stereos ? Also is there a detailed list of items to purchase?
Thanks
@@kylefetes454 No there is no wiring diagram included, which made the builds difficulty much greater if you dont understand the components. As for a purchase list he does include one but there are a few things he doesn't mention in the video that have to be purchased as well
What would you say the most difficult part of the process was?
I can just imagine all the hours put into this build, and that shows in the quality of the video.
Very well done!
As a DIY speaker enthusiast, this is nothing short of legendary. The design, the effort, the result are almost unprecedented
i am quite confused how he conected the speakers to his pc ... i have never seen an amp etc being integrated in a speaker yet ...i have an external one with speakers from tsm that are at least 60 yo ... am i just to stupid to understand it or did i miss something?
you dont know how active speakers are possible? he just built the amp into the speakers and fed the in built dac a digital audio signal from his pc@@duesenantrieb8272
@@duesenantrieb8272 its actually pretty common in most studios for mixing/mastering applications, like active nearfield monitors. I'm using Yamaha HS7 (6,5" sub) which has each a integrated amp. It's the best case to do it like that if you want the amp not changing anything unexpected on the frequency band. Every amp acts kinda differently, and could end up with peaks and dips in the freq band. If you match the amp directly to the speaker and calibrate it at the end of the production steps, you make sure each of them sounds almost the same. you always have slighty difference with 2 speakers, if you dont buy matched pairs and even these matched pairs are not performing 100% the same, but as close as it is technically possible. So in the most cases you wont notice, even with unmatched pairs of speakers.
@@duesenantrieb827216:42 shows them using a DSP with a phono input going to an amplifier
@@duesenantrieb8272 He installed a DSP chip; digital signal processor. This communicated with the software on his computer
Brilliant. When I was 16 (in 1980) I built two high end floor standing Monitors using KEF drive units with Bass transmission tubes. It was a defining project for me and my engineering career. My son is now 16 and I would love to see him make these modern updates. He has already built a custom gaming PC after seeing your other videos. Great project.
That's really cool to hear! Best of luck with the build!
@@DIYPerks Hey matt this is sort of out of the blue, but if you could do a video on an AC uninterrupted power supply video that would be great.
The only videos available are basically of powerbanks, but these arent capable of uninterrupted power supply.
UPS aside it would again be great to see what you make with wood brass and aluminium and it could be paired with your current computer setup.
Thanks for taking out your time!
Very nice
I have been watching your videos for a number of years as you are a great inspiration and I love to build/DIY things myself. This is another great example of what people can build at home with excellent results. As always, fantastic video! Thank you for sharing your ideas all these years and I hope you continue to do so for many years to come. :)
This is by far the most inspirational video I have watched in years! You're level of detail is unmatched and I cant even imagine the hours you poured into this, not to mention this incredible build video that was so well done. For sure a goal of mine to build this in 2024! Thank you!
I laughed out loud when he said "for stereo I've made an identical pair" and pulled out a fully built second unit out of nowhere. So much effort obviously went into making such a beautiful set of speakers!
id imagine he built it off camera and possibly in half of the 1st one
still impressive though
"and, just for fun, I've build 5 more units for a full 7 point surround sound experience. But two should be just fine for most."
I have been designing speakers for years, and gotta say that this is probably one of the most well executed diy speaker builds on youtube. Yeah, you could do some things to possibly improve on this design, but you would be chasing relatively small performance gains and it would probably cost a lot more money. Two thumbs up.
For arguments sake, what kind of improvements would you suggest?
@@stefanionescu6357 Arrangement of the drivers. IMO Twitter/High should be place on top, Mid-tone should be on mid
@@marktamparong8618 shouldn’t the tweeters just be placed at ear level, which seems to be exactly where they are when sitting in his desk?
Clearly the speaker is very bass heavy, so there are lots of things you can do to improve the design. Also why on earth would you amplify each speaker... Not a smart design honestly
Meh, give me a Troels design or proac.
This video was truly a gift and the finest example of inspiration.
Your efforts are appreciated on behalf of those who haven’t taken the time to share….

The clarity in sound is amazing!
Thank you for showing how difficult it is to make good sounding speakers. There's a lot of science involved that people often overlook.
@@TrickyDicky2006 Precisely.
There are plenty of DIY speaker designs out there that can be completed by more inexperienced builders, where the engineering and design has been done for you.
A conventional 2 way bookshelf speaker can be easily built but still provide exceptional sound.
There is no good-sounding speakers. Only honest speakers.
@@nobnobnobnob I'm pretty certain there are bad sounding speakers, therefore, it stands to reason there are also good sounding ones. But point taken. :)
@@TrickyDicky2006 never met anyone who can tell the difference between a $400 and a $40,000 pair. golden-eared audiophiles are very embarrassing
I always like the fact that you never rush into uploading videos but taking your time and give the best results
your work here is absolutely SUPERB and attention to detail is absolutely NEXT level. your speakers have far better stage and depth than the bookshelf speakers you compared against.
I love this build. I only recommend flipping the fans around so they pull rather then push. It keeps dust out the best. Gamecube took this method and all you had to do was blow air on the fan to clean it
Didn't see that veneer/spray paint finish combo coming, but it looks great! Really enjoy seeing you use new materials and combining technologies like 3D printing and plaster of paris. Great project as always, Matt.
Anyone who didn't see the wood veneer coming must be new to the channel.
@@robbiepoohify exactly. the moment i realized he taped the sides off instead of painting them i was immediately betting on veneer. cant argue with the results tho, it looks preem.
I agree that the veneer looks great and is a nice touch. I have another idea for an upgraded look though; how about gluing on some thin leather or even faux leather to the front baffle instead of paint? straight piece of leather and then cut out the speaker holes...
But… the thumbnail 😭😭

FR bro
thanks for putting so much effort to deliveri excellence. I am an audiophile and I make amps as a hobby, I understand there is a lot more involved in sound desing. But, this is so far the most educative, precise, easy to understand and to the point video I have ever seen on the topic. Wish you enthuasim to do more of what you do.
A detailed, compressed, thoroughly explained adventure is the ultimate youtube application... thank you
Seeing most of the builts on youtube I'm usually nitpicking in my head all the imperfect decisions or minor errors done in the built process. But in your case... Just hats off to you Matt. The build is perfect as always, and you go above and beyond to create great solution, and not just a prop for a video. The superb video quality, all the additional instructions you provide - hats off
Build is not perfect. Would like to see spl at those 35hz. Small enclosure, small drivers and transmission line. There isn't perfect build in audio and with amount of offort he put towards it you have better options. Printing is way more expensive than do it from mdf and its way less sturdy to although it doesn't matter at those pressures
Soldering directly to the 0.1" headers on the DSP was A CHOICE :D
Decent build, but tweeter is big, and far away from midrange.
@@wadimek116 Printing is more expensive? XD Like printing can be close to pennies for this amount of plastic.
Here in EU you can often get a roll, 1kg/2lbs, for around 18-25usd.
Plaster of paris is basically free.
@@wadimek116 Depends on the material. I've been using carbon fiber reinforced plastic (but with SLS printing technology, not FDM) for headphones and together with the complex designs been creating parts for headphones that are far more rigid and acoustically inert than anything I've come across from headphones available on the market, at any price point. Yes it's expensive, but building a headphone like that still costs less than the regular headphones on the market that perform worse. Using that type of plastic for speakers would be way more sturdy than MDF or any wood while also allowing complex shapes of the internals of the box to be printed in one go. It's actually amazing how more people aren't catching up to this by now, considering how easy it is to make stuff that just wasn't possible not long ago.
Just bought the files and kicked off the first base plate print!! Your videos are next level mate! Thanks for putting in the effort and sharing with the community!

This was really good . Upstanding work . Everytime i come to see your projects, i get really excited . Thank you for existing ❤
I really appreciate the way you do the audio testing comparison segments. It's so much easier to hear the difference when you seamlessly join the different samples. So many others just play the samples back to back, which I'm sure is easier to edit, but not nearly as effective to get a good comparison! Thank you for another incredible build and video.
Yes, I thought that as well, but didn't manage to articulate it as well as you did

This is insane! I came into this video expecting expensive tools and laser/waterjet cut wood, metals, and acrylics. Im shocked you made something that looks so traditionally crafted so easily and efficiently. All the prototyping that went into refining the design is very apparent.

You're videos are absolutly amazing and i gave rewatched them countless times
You also inspired me to build my own speakers
This is a great video! I used to be one of those "dime-a-dozen" Yankees in the 1990's building my own subwoofer enclosures for car audio from scratch. But unlike all those other guys, I used science and math to perfect enclosure dimensions and materials and construction techniques to maximize sound quality. For instance I built a home theater sub with 4" woofers from Radio Shack way back in the early 90's and it sounded absolutely amazing. It shook the room! So I can really appreciate this video.
You mean there are actual applications for math outside of my high school textbook, and bank account? lol. People love to toss Tesla's name around. When they haven't realized just how good the man was because his approach was not to simply build a device, but perfect that device as well. That is why there is little difference between generators and alternators of the turn of the cuntury 1900 and today. In the 1880's Tesla "perfected" those devices by caliberating their frequency and vibration. I'm sure you know such devices have an output like a triangle. As RPM's increase output increases to a point once reached further RPM's see then a decrease in output capability. And Tesla did that for us after inventing those devices. And why we owe the man so much respect because he happens to follow us around every where we in our world today and with us Tesla following right along. lol. I absolutely love his apparent lack of fear when dealing with electricity. And his idea to not use wire to tranfer it where you want. With just that one little problem called a "sonic boom" terryfing everyone around him back in his day. Truly a great man that society did not treat too well thinking "magic" instead of "science". And wish Elon would maybe do that for the man since using his name for Elon's business. Respect kinda thing. take care. and enjoy those speakers! "If you refuse to grow up, you can never get old!"
This is so far beyond any PROFESSIONAL effort... you could easily challenge even Bang&Oloufsen here. Quality galore.
The amount of work you put in to making all of your projects top quality is immense. And doing so in a way that others can follow along is really special.
This is absolutely brilliant, thanks for sharing your ideas so generously!
Phenomenal build and sound quality!🤯 Absolutely amazed at how vibrant and punchy the bass was in comparison to the high end speakers!!
I can loudly say that watching your uploads are not a waste of time but instead a treasure trove of learning, ideas and DIY wisdom!
fuck yeah
Impressive design, however I encourage you to try using coaxial speakers (as a mid and high drivers). When sitting up close to the speakers it is important that the mid driver and the tweeter are aligned in phase at all listening positions. That requires the drivers to be as close to eachother as possible. Doing that will make the listening sweet spot larger. You could also try to put the tweeter and the mid driver in a single waveguide/horn. Or use a tweeter that can be crossed-over at lower frequencies, like the SB26ADC. Also^2 take a look at "constant directivity speakers". It's something Im trying to learn and build now. Hope that helped You, or whoever else who reads this.
Does having the drivers vertically separated rather than horizontally separated mean that the listening sweet spot is only being restricted vertically? So for example, if you were sat on the floor below the speakers they'd probably sound bad but if you're sat around the same height as them then you're probably fine anywhere in the room?
@@lukebetterton From my understanding, yes. If you keep your head level you could move left or right and still be in the sweet spot.
Dipole Ribbon Tweeters were the best I've heard so far. Ultra realistic sound, like being there.
There's no way to achieve a magnitude response as good as that with a coaxial design in such a slim enclosure. Sure, the soundstage will be better, but the low end extension will be significantly lessened.
@@Fowly My point is to keep the tang band subwoofers as they are but change the midrange driver and the tweeter for a coaxial woofer. My reasoning here is since bass sound waves are really long, few centimeters of distance between drivers won't really hurt the off-axis magnitude response in the bass region. (1/2 wave of 200Hz is 85cm in length)
Outstanding on so many levels. Props to you for your skill, knowledge, and passion.
I’d love to see this concept simplified, then expanded first to a standard surround, then to a full 3D setup with the multiple height layers.
A class I took in college did something like this with standard speakers, and the result was jaw dropping.
Intelligent wiring and audio control and the sheer number of speaker installations you need mean this is a pipe dream for most, but if it were done DIY with some 3D printed speakers, it’s something that could be a more feasible DIY project for enthusiasts.
As an acoustic engineer, I must say that it is very impressive. The magnitude response is fantastic for the size ! I'd love to have those for my TV.
Also, doing a three-way design by adding the tweeter isn't just for high frequency extension, it also yields better directivity. When the wavelength of a sound becomes bigger than the driver, it becomes omnidirectional. It makes the off-axis magnitude response quite inconsistent, which is bad because it can be heard from the reflections of the room. A three-way design minimizes that, so it has a superior soundstage !
Being omnidirectional is not a bad thing and has nothing to do with adding a tweeter anyway - adding a tweeter does the opposite thing, preventing the larger full-range driver from beaming in higher frequencies. The bad thing is that it adds lobing and the driver spacing here looks particularly poor in that regard. A speaker being three-way is not intrinsically better in off-axis response, the main benefit compared to two-ways is decreased intermodulation distortion.
@@erkkijaakkopetteri I didn't say omnidirectional is bad, I said that if it is the case at some frequencies and not others, it will create an off-axis magnitude response that is different from the on-axis, thus making the soundstage wrong.
I think that the driver spacing is fine here. This is a very slim enclosure where waveguides are out of the equation, so the vertical directivity will be poor no matter what, even with more optimized driver spacing. Plus, having the midrange driver at the top is a classic trick to lower the minimum listening distance.
Because it is a relatively near-field listening setup, intermodulation distortion should not be a problem here if the drivers are half decent. Eventhough it's quite audible in test tones, it's actually very difficult to pick up when listening to music. Frequency response and directivity are by far the priority, so the more consistent dispersion of a three-way system is its main benefit in this scenario, especially without any waveguide.
@@Fowly I mean, almost all speakers are omni at lowest frequencies and more directional at higher frequencies. It's not a problem and a speaker being three-way does nothing to solve what you're describing anyway. The enclosure being horizontally slim has little to do with the vertical directivity, that's no excuse for the driver spacing. Yes, mid at the top is good, but the spacing between the tweeter and the mid is objectively awful.
IMD is definitely a problem in many two-way designs, near-field or not. It might be difficult to intentionally pick up but it is a significant thing. I agree that FR and directivity are more important, but once again, the speaker being three-way offers no fundamental improvement to directivity unless the two-way comparison is fundamentally flawed to begin with.
@@erkkijaakkopetteri Mid-drivers and tweeters also become omnidirectionnal in their lower frequencies, the effect is just lessened because of the baffle absorption. But, it is definitely a problem in crticical dispersion angles in the 45° to 90° range. A slim enclosure like that doesn't allow waveguides to be used. So, a three-way system helps a lot in that regard.
I understand what you mean for the driver spacing, but I don't think that it would make an audible difference. Maybe the sweetspot could be closer, but regarding vertical dispersion, it will be poor no matter what. So if we're going for more precize optimizations like that, what should make an actual audible difference would be to put absorption panels on the ceiling 😅
And yes maybe IMD/MTD could be an actual audible artifact but in my experience, if the drivers are half decent, you really have to play the speaker very loud to hear it. Maybe loudness was priority for this project, it wasn't mentionned anyway.
@@Fowly I think I see your point now, but can't agree. The TB subs require crossing low enough that the transition to the fullrange speaker is basically omni and thus smooth. Adding the tweeter makes things worse when it comes to a smooth directivity. In any case, if the tweeter flange plate was removed, it could be placed a lot closer to the mid, significantly reducing lobing.
The level of enthusiasm you have for your projects and videos it’s just great to see someone so excited and enjoying themselves in the process.
This chap is worth every minute and second of my time
Wow what an incredible video! As a fellow DIY'r and Professional Product Designer I can really appreciate the huge amount of work that has gone into this project and really respect you for sharing it publicly! You certainly have a new subscriber and I'm definitely keen to give this project a go.
Out of interest what made you go the 3D printed route at the beggining over a potentially easier and faster CNC particle board option?
This couldn’t be better timing, Matt. I’m currently looking into building a set of speakers and all the info and parts recommendations in this video are extremely helpful. Thank you!
I always love how much attention you put into the detail of your projects! The speakers turned out great!
In college, I made powerful, crystal-clear speakers out of 3/4" plywood (glued and screwed, of course), out of unusual shapes and using internal baffling. I used Lotus 1-2-3 for the calculations, and an old book I found in the library.
I took a look at the links for your drivers. Impressive! I might get back into it...
This (IMHO) is one of, if not truly THE, best of your projects ever! Thanks for allowing us to cheat off of all your hard work!
Many printing enthusiasts these days have much larger printers, ( and I'm guessing you do as well ) so it is very thoughtful of you to focus on an entry level size machine to enable the largest possible audience to benefit.
Your engineering skills are top shelf, and your attention to aesthetics as well is to be lauded.
I'm just about to start printing a set of large floor-standing units I designed for my Modix Big60, with 10mm walls.
I have to say, I am quite envious of your collection of testing and analysis tools and software!
As a beginning printer who might actually be silly enough to attempt this, I appreciate it massively!
@@vulpinemachine Do tell how it went. Just yesterday printed my fist print
Incredible high quality content! Once again, thank for for your efforts! Not many DIY youtubers actually put in that much effort to their products. Hats off for you, sir.
Amazing work! Congrats!
One of the coolest DIY channels around.
Class is in session...
Thanks.
WOW, the quality of your projects is nothing short of phenomenal! I always get excited to watch another of your projects come to life :) Thanks for your continued dedication to perfection
This is freakin awesome buddy. As someone who worked in car customs for many years, (stereo system installer) and I just love your channel and what you do. This is so awesome, especially after all that hard work, (trial and error) you give your blueprints away for free.
Hands down, one if my favorite channels on here.
Amazing work, super modern approach!
I don't know why you always make something not only useful but also beautiful, especially when you are using wood in your creation...very good job!!! I like to watch your video, always!!!
Wow simply wow. And there I am making small speaker cabinets out of plastic sheets... You've simply gone above and beyond with it, perfecting it to the point where it can't be improved anymore. And the aesthetic design, as always is amazing too!
Really great. You should be sponsored by the whole DIY 3d printing industry. You have made them a great marketing product here. Love the amount of research and development you put into every build. Also a very entertaining and well made video. Thanks
Seriously. Price of the 3d printer and materials are likely less than the expensive bookshelves. A lot of value to be had.
Genuinely wonderful video, thank you !!
This is incredible! Placing my order now 😁
It never stops amazing me how proper DIY Perks' builds are. Every step along the way there is attention to detail and much thought. Very impressive and inspiring!
I used to make speaker boxes in the 80s using similar techniques with an equation, calculator, wood, saws, ports, filament, etc. I find this evolution and your video quite satisfying. Kudos to you sir, great video!
I've made my own speakers and the only "complaint" I have here is the whole being astonished by 35Hz. It's impressive for a 3" driver for sure but you can easily get that in a good 5-6" midrange in a basic bass reflex box. I have two pairs of bookshelf speakers that dig into the 30s one with the Aurum Cantus AC-130MKII which by volume is probably actually smaller than this box though a bigger footprint, the other is a behemoth though with a ~7" Adire audio extremis 6.8 and that one I think hits upper 20s with good placement.
Really cool design and video though.
I absolutely love your stuff. I watch all the time and have my own ideas that I potentially could build with the knowledge gained from your stuff. Shame I don't have the money to try anything but still maybe one day! Anyway, never stop and I love it all ❤
Great work. The level of effort you put into this project is nothing short of astounding. Using an Elegoo Neptune 3 Max (build volume 420 x 420 x 500) would allow you to up your game. OBTW I have a MK3 also. They are great little printers.
you're project are always so incredible! I am into sound and was not expecting to see those speakers tested with REW and a calibrated microphone!

@@davidc756 I'm usually the one correcting those monstrosities lol! Can't even blame auto correct as I was on a computer 😂
When I woke up this morning I saw a notification for a new video from diy Perks, I knew at the point it was going to be a good day! Thank you so much for sharing your projects and knowledge while keeping things affordable for everyone to try. I am always looking forward to seeing future projects 💡from you! 😁
I can't believe you figured out how to make those. They look and sound incredible! Well done.
Much brighter sound and sounds to be tighter in base. Well made and executed. Excellent choice in hardware.
You did such a fantastic job! I can see lots of thoughts have been given on the detailed features of the 3d design, especially the joints of divided up components. Some features are way better than I (as a former mechanical engineer) have seen in real mass production design. On top of that, you put together the circuitry and programmed the DSP, amazing!
This is on a whole different level. Your videos quality are outstanding as well as the content you're making. Congrats on the effort and time you put into making these videos for us!
Amazing! I'm always surprised by how far you go to make it perfect.
Mate that's next level genius.
U spent all that time and money to help people have amazing speakers at a low cost.
Mind blown and thank you as that looks like it was a very expensive and time consuming with all the prototypes but u did it. U beat Bose sound bar by loads xx
THAT WAS INCREDIBLE!!!!!!!!!
Seriously dude probably the best thing you've ever made. I am tempted to try build my own speakers now. The quality of the sound is absolutely superb and the finished look of the speakers makes me wonder why you dont found a company that builds these speakers and sells them to compete against other brands. Your approach is very scientific and i love it. Please found a company.
I´m really speechless.
You put more energy, brain and effort into the design than a whole company would.
If we could clone you - problems of the world would be solved in a couple of months .
Thanks for combining a lot of ideas from different subjects in your projects!!
You'd have to wait for the clones to grow up, though...
I think sooner or later he will get his head around on cloning himself
If he worked for a company it would take months to do this because of the progress/status meetings, phone calls, team training, mobile app training, morale meetings, AI prompt training, diversity and inclusion training, etc.
@@dchall8 I think we could do without that last bit of training at least... lol

Thanks for the PVA tip! I am working on a bluetooth speaker project and was planning to fill the void with plaster of paris. Glad I saw this vid before I got to that stage!
This is an amazing build! Thank you very much for sharing the knowledge 😌
I’ve been watching your channel for years. You have improved your videos to an unparalleled level of professionalism. Absolutely incredible work!
Dude, you are truly amazing! It's magical how you are doing exactly these kind of projects I have in my mind but never gotten to. Your production quality is just increasing for each video! I really like how you don't dumb it down too much and keep it quite technical so it's easy to understand why you chose x instead of y and a wide range of audience can follow with. Great job! It's too bad you can't sub two times, you deserve it haha.
What an impressive project 😮
Congrats as always!
this is all we could ever wish from a diy perks video
you really have quite a monopoly on super high quality videos of insanely good builds for very little money
I will never do any of these projects and don't understand most of the specs... but there is something so entirely cathartic about these videos. I never miss one!
You should make a book with a lot of your "re-invented" things. I know, who reads books anymore, right? But this really is a great thing to have if you're tinkering in your garage or want to gift a tinkerer something. Make the projects have QR codes to necessarily files and lock them up behind a unique key that comes with each print and tada: You've got yourself quite a system!
Love the video and can't wait to find someone to help me build some
That sounds like a great idea.
We had a popular magazine called "popular mechanics" that often had reader-written articles / diy projects that was absolutely fantastic to try at home. I can imagine a whole book full of DIY projects with photos and all that would be an incredible gift or addition to a bookshelf :D
I read books
This is amazing! Congratulations! Really great work!
I found myself so enthralled I wished not to abandon this video. Fabulous.
