One thing to note: I did not have the subwoofer placed like in the video. I had them in the left corner. Obviously this was hard to film so we brought it out for filming purposes.

I was triggered when I saw the tube amp right next to it 😂
Earbuds for Kef M400 250 euros for a pair of earbuds in replacement, for headphone bought new 50 euros (original price of the headphone 250 euros, or the price of this spare part), while the leatherette is very thin and quickly detaches itself? I expected about ten euros, which I usually put in the competing models. 25 euros would have seemed very expensive, too expensive considering the poor quality, but 250 euros (240 Pounds) is unfortunately not a joke, but an incredible bullshit and a deliberate merchant choice that corresponds to wear and tear. I have always been faithful to the Kef brand for 40 years, but I understand that we are actually taken for pigeons, frankly it is like urinating on us. Fortunately Kef is not a car manufacturer, he would sell the 4 tires at the same price as the new car! Also, we notice that the construction of these earpieces does not correspond to what they seem to be, that is to say a natural rubber of good thickness to withstand time. In short, a good sound quality, but of the whole issue manufacturing, and a sales policy that is obvious robbery.
@@dugenounonplie8162 And your point is ? I thought we were talking subs here 😉
@@jimfarrell4635 My point is that KEF was a fantastic compagny, but is not still today ! A big shame !
@@dugenounonplie8162 Fair enough, Dugenou. It just seemed a bit of an abrupt shift in topic. I do feel Kef remain highly innovative but some of their pricing can indeed be off-putting.
Top review Jay - loving the backdrop and professional production quality, you really are taking it to the next level man!
His listening room looks heavenly!
Nicely planned out isn’t it - inspired me to redo mine!
I just got the Metas. Love your reviews. They are always helpful and unbiased. Thanks!
Really happy I found this channel great great review dude
Got the old ls50 with a rel t7 also very nice setup sound incredible
Exactly as mine fed with marantz integrated amp & CD a very well match set up
I really appreciate your honesty! Please stay as independent as you are. That makes the worth of a review!
I have the LS50WII + KC62 combo and it is truly fantastic. Awesome for both music and home theater. Perfect marriage.
I bet.
one or stereo subs?
@@ISETbioDev.Cottaris one. I have the LPF set to 45 Hz on the KEF app which is about the -3 db point for the speakers. Integration was super easy. As Jay mentioned the bass is very fast and accurate and incredibly deep.
Yeah, I have the LS 50 Wireless ii as well with two REL T5I's, and the KEF app definitely makes integration a breeze and there are more features coming. The EQ settings make this a very tunable system. The other parts of the app in regards to the streaming services needs more work.
@@LuxAudio389 agree. The phase correction is also pretty cool.
Mine arrived today. Using it with a pair of Kef LS50 Meta's and a NAD M10 in a nearfield setup. The sub woofer it's replacing felt and sounded like a sub whereas the KC62 sounds more like my meta's just got WAY larger and more powerful. They pair incredibly well, I'm crossing them over at 80Hz.
What's the best crossover + volume setting when paired with Metas? I'm driving them with a Hegel H190
Curious are you high passing the Meta with KC62 as well ? The Kc62 are one of few subwoofers that gives you RCA high pass.
Wow, that sounds like a great product! Glad to hear it wasn't just outlandish specs put on paper. Thanks for the review!
After looking at REL and SVS it looks like I just found the sub for the Ls50 Meta I ordered yesterday. Many thanks.
REL also blends great with most speakers
what you are "feeling" is the low bass. Measure this beast, if you get a chance and have time! ! Thanks for the review/presentation.
So, instead of upgrading my original LS-50s to the Metas right now, I believe that I will put that money towards this subwoofer first!
Thanks Jay! Great content, as always.
Totally agree with you.
I am sure you'll get more benefit adding the KC62 than changing to the Meta.
I think any well integrated subwoofer is an upgrade to the LS50's. However this new line of kef subs seems to expand on the previous generation products. Pretty cool!
Seems like a smart move to me. Give the meta some time to work out it's bugs.
Hi Cory, I was wondering what your opinion is on the LS50s? I have had quite a few speakers to date and find it hard to believe that a speaker this small can reproduce a full range quality sound. Would love to hear your opinion.
@@grahmpike9032 They don't have much bass. They spec at 79Hz-28kHz, +/-3dB, with a -6dB point of 49Hz. They will measure in the mid 40Hz range in some rooms. IMO, a well integrated sub is a must for some if lower bass and impact is desired.
Hey thanks for testing it with the maggies.
Beautiful room and setup. This could be the setup to live with.
Thanks for the summary type review. Your description conveys all the info needed. I appreciate the use of both KEF and Magnepan speakers paired with the KC62 sub. The pro/con of the wired connections takes the surprise factor out of the picture.
Have just got the mets and now getting this Subwoofer will it be Fantastic 🎵👍💚
Thanks for the review, I might have to give them a try.
Would love to see a review of the sub with the LS50W2.
Most important thing: How does it make the main speakers (LS50, for example) sound? Ideally, it should transform a speaker like the LS50 into the best of all possible worlds -- the advantages of a good small speaker with the bass and scale of a big one.
It does!!
@@mikhailyadav Do you have the LS50 Meta with a subwoofer ? If so how are you integrating the sub ? Thanks
@@kevtn8 I have the same question, did you receive a response? I like the idea of speaker inout but without speaker output to the mains I guess we’d need to run another 2-ch amp , or use the rca in and outs ??
Excellent review!!! Such a small sub. Love it!!! Kef is next level for sure. 👍
Great review, now I have to buy it.
Looks wonderful in white. Sounds great too. I am an LS50 / KEF fan for sure. My only concern, as with any powered speakers, is their longevity. without issues. At its price, it needs to be problem free for 20+ years IMO. Many techs will not work on actives...heat problems, difficulty of getting parts long term, etc.
In that case stay away from the Active version and stick to the passive Meta.
I certainly did. I bought passive.
Jay, just some advice as to high level inputs (no matter the brand). Make a octopus cable (gauge of wire depends on two factors, length and output), at the sub end as in the case of the Kef, make a short jumper. I have been making these in my business for years with great results.
I hope you're able to review the KEF KF92 one day.
Enjoyed your review, Jay. The KC62 looks great, and I love the size. Reminds me of the Sunfire subwoofer from about 20 years ago.......similar compact size with 1200 watts, 6.5" woofer, and two radiators on the sides. Those sounded great too, blended well with any bookshelf speaker.
Ding ding. My Sunfire True Sub is still chugging along (after a plate amp replacement) with my Mirage HDT's, but the KC62 will definitely be on my short list when it's time for a replacement.
You can get that sub for $99 now! Times have changed.
this is exactly what I was thinking of doing today actually... LS50 Wireless with a pair of KC62s configured as a full-range 2.0 system. Clearly I'm not the first...
Great informative video! Subscribed!
I love those speakers and if I had the coin would definitely get a pair.
If i ever decide to get ls50meta im getting that sub!
Hey Jay, Great review! Like your new decor and sonic room treatments - Can you do a video about what you did and the products you purchased?
Just got a ZA3 amp/KEF q150 and SVS Micro 3000 .. Incredible sounding system. I actually wish I had the Metas, NGL . But I don't know much of a difference it'd make over the q150s. Never heard em in person.
Great video keep it up 🔥
Interesting Video, but I would have loved to see some measurements. Would be nice to find out how low it actually goes...
Yes you need Hz spectral analysis , balance of it , obviously this may be tweakable away from the default or stock
I think a good trick would be to make stands for the ls50 to take up even less space if you want. I just bought 2 jbl 550p to set my jbl 580 on. Takes up only the space of the subs.
Why did you say use a thin gauge wire but not tell us what gauge you used to connect the high level input? Please help.
Hi, great review. Do you plan to test the KC62 with the R3s? Also, did you highpass the LS50s ? And if you did, did you use the highpass output of the KC62?
I was prepared to ask the same question. The sub has speaker level IN but no speaker level OUT that I could see. So, bass management somewhere in the mix? His praise for the sound of the bookshelves suggests, "Yes".
I guess it’s like with Rel - speakers go full range, sub’s added from below. Works fine for me btw.
@@oleksiifilippov68 if the ls50 mid-range driver goes full range, them there is no benefit (to the ls50) from the sub . it would be better if there was offloading of low frequency stuff to the sub, so that the midrange driver can do a better job of transducing the mid frequency signal.
@@ISETbioDev.Cottaris oh, there’s a benefit. I run a sub just like that. More depth to the sound, fuller warmer midrange...
@@ISETbioDev.Cottaris You can do this if using LS50WII (through the app) or if using separate pre/power - wire up pre->KC62->power - the line output maintains stereo, and has a high pass filter that can be applied (the DIP switches on the rear)
Nice review
One of the less obvious benefits of the shared magnet structure, is there are big efficiency gains, and reduced magnetic induction distortion. The concentric voice coils actually cancel some of the magnetic challenges that all subwoofers face. Here is a white paper from KEF on the KC62: @t
At $4K for the set it isn't cheap. I've got the LS50's and I'm wondering if it would be worth it. Nice review!
I would imagine you could do better and cheaper than 4k plus HST.
Love the name! Greetings from eastern Canada.
Thank you for this review....might be time to replace my B+W subs!
What a great looking mini sub the likes of which hasn't been seen since sunfire and velodyne's offerings. I agree, it looks like you're overdriving that sub with the extreme excursions of the woofer. How loud was the KC62 playing when we see those drivers wildly fluctuating?
Hi Jay! Love the channel. I know this is from several years ago, but if you (or anyone in the comments) could share thoughts on the LS50 Meta/sub combo versus R3 Meta with no sub for 2 channel listening only that would be great. Take care and thanks for all the great content!
Sitting here trying to decide whether to keep my Buchardt A500 order or get Kef Wireless II's w/KC62 Sub. I'm sure I'll be happy regardless.
How they speakers did not have to produce the low frequencies and played louder?
Did you you high pass filter?
Thanks for the review, it would have been nice if you test it with an SPL meter to see how low it go.
Reviewers always seem to use plodding bass heavy tracks to demo subs. To me the true test of subwoofer integration should be with music that has good pace, rhythm & timing (PRaT). If it can keep up and NOT draw attention to itself then I'm interested.
I agree. But regarding not drawing attention to itself that should be able to be done with gain level, crossover point, and phase. Also room placement.
there's a number of well engineered organ recordings out there (Telarc, Reference Recordings, Wilson Audio etc.) that are great for that.
I asked my mentor in the high end audio design industry and he said:
What they do is tune the box to 50hz and then EQ the sound and reducing the input levels on the higher bass frequencies such that the really low end is now louder by comparison and then they throw 1000 W at it and call it a day.
Imo Their claims of 11 hz is laughably absurd.
I am more of a high-efficiency nut myself. I like getting as much as possible out of as little input as possible, but those type of speakers can get very big very fast
That said I’m sure it sounds fantastic and you just cannot beat the size and Output
How are the LS50's less hard to drive with the sub present? You're still sending a full-range signal into them unless you pass them through the sub and out with a high pass filter
Jay, what is your room size? I feel it's important to include the room info in sub reviews. Not sure if this would work in my room which is 22m^2 (245ft^2). What do you think?
Kef, why was the driver painted silver? would have wanted it in the same copper color as my wireless 2.
The stand out performance specification of 11 Hz is impressive, but this will only be possible at low levels. At higher levels, where you can actually feel the bass, there will be a limiter, so the question is at what point the limiter is active. I would prefer less extended low frequency on a sub like this, and only let the limiter affect the sound at high levels.
Small in size, ability to play deep, ability to play loud. One only gets to pick two of these. Cannot have all three.
What do you think would be better for Ls50 wireless 2. The KC62 or Rel T9i?
A comparison to a Rythmik F12 would be very welcome.
Reallly looks cool. It’s just straight too expensive full stop (imho). Add this money to the LS50 and get a nice Floorstander. And then just save up a bit and buy a cheaper sub half a year later later and you’ll have a real full range set up.
ITs not , its cheap , but by the time it gets to you there are all kinds of taxes on it , this is what i realized some time before. The prices are actually very low , but the system is such that
you dont get money first thing , and then all kinds of parasites take part of that price .
If you were KEF you would want a higher price , becase what they get is fraction of the price you pay . This is the problem .
The problem is most floor standers don't go remotely low enough to replace a subwoofer. You'll need a sub even with most large floor standers. And often the location that works best for your speakers don't work best for low-end fidelity so having a sub that you can move around separate to your front speakers is key.
@@mohamedahmed1023 yes the advantage of subs is that you can put a speaker in the corner if you have a sub , because mids and highs dont care as much about being in the corner .
But far as bass goes , floor standard have the most out of all speakers for they are the biggest .Of course .
Comparatively they have more then bookshelf and similar .
In my experience 8 inch gets you far enough , the bigger the better .
But if you go to 10 and 12 inch that can be hard to implement .
They are slower so they dont blend in good sometimes .
Its hard to say , every good room is different , but every bad room is similar
:)
@@dedskin1 Agree. How slow your bass is often depends on the design of your sub and, more importantly, to your point, the location of your sub and whether you have two.
I have studio monitors that have 8" woofers that are flat to 40Hz and can reproduce a decent amount down to the low 30s. That's comparable to what most floor standers will provide.
But I added a single 12" sealed sub and the bass was deeper and faster than just the studio monitors. Adding a second 12" sub helped make the bass even cleaner at several listening positions.
In my experience, the easiest to integrate/ set-up way to get full range sound that's fast and reasonably sized is to pair bookshelves with two subwoofers and leave the bass to the subs. And I find even 8" woofers aren't quite enough for me.
@@mohamedahmed1023 yeah , it gets complex in a hurry .
I have a simple setup , MB Quart 650s , cheap speakers but all the elements are there , 3 way , titanium tweeter , big box big dome mids , and ive put in different bass drivers , original ones were good paper driver , cant say its bad .
But i took ones from studio monitors 8,5inch SB acoustics bass driver .
Retails for around 200$ , good driver
And ive put that in .
I though honestly there would be more difference .
I have 1 original ,and 1 SB acoustics .
So im comparing .
Im struggling to tell the difference but in some songs it can be heard that SB acoustics one is tighter but on low mids .
Bass is kind of same , i took measurement microphone DBX MK2 , and it detects some difference .
But as you know there are nodes , and stuff going on in the room its hard to say . i didnt measure at the same spot .
Maybe ill do it later , but kind of similar response .
Would love to learn more about measurement , and try to see what driver is better in what .
Also compare difrent speakers .
Would love to compare B&W Book Shelf unit with Studio monitors
To see is 2000$ worth it for a bookshelf , or you get the same with say 500$ studio gear , Yamaha or something .
Cant find anyone doing that kind of comparison .
Hi Jays! thanks for your review. Its very helpful. I have a one question, for a small-medium room you recommend a one K62 or two Rel (T5x or T7x) ?
The combination of the KEF Meta and one KEF subwoofer will set you back £2400 in the that amount of money I can buy a really good pair of full range floor standers with none of the negatives I hear in the KEF Meta's and have change. My existing Castle Howard S2 speakers provide more than adequate bass for home theatre so would expect to achieve the same with the Quadral CHROMIUM 8 s. Stay well. Daniel
I just purchased a KC62 and a pair of q150b bookshelf, could you recommend an amp or receiver with the smallest footprint possible because they are for a tiny bedroom 8 by 10 to connect them to a computer for music and movies.
Looks like a good idea to put 1 each behind speaker since it is small.
I don't get how the LS50s are easier yo drive louder with the sub. Does that mean high pass filtering the signal to the amp?
It’s got to, right?
It's because the mid driver on the ls50s dont have to work as hard trying to also handle low frequencies. You would be able to play them louder and they would have even less distortion. I have ls50w with relt9i
@@nikkieb8908 how do you filter those out with a stereo amp? ;-)
You continue to load the speakers with low freqs..
@@RicardoLeonardoAugusto The KC62 has an adjustable high-pass filter. Essentially your preamp goes into the subwoofer rca line input and the rca line output goes to your power amp/speaker.
@@ThujanK That's not how Jay has it set up though.
Great review so much explanation
What will be max room size it will handle without going down.
I was considering 2 Rel T5"s or 1 T7 for music purpose with LS 50 your review changed my mind.
Please let me know Rel T5/T7 or this Kef sub is better for LS 50.
Thnx
This is my EXACT dilemma right now. Just got the wireless 2s and and very torn between these 3 options to pair them with.
Got the ls50 with rel t7 is sound very good
I demand a type of socialism where I am paid in speakers!! =P
Great video!
Is the KEF LS50 Meta +KC62 better then a setup with KEF R3 or KEF R3 with KC62?
Great review! If you have heard the Sonus Faber Sonetto IIs? If so, how do you feel they compare?
Is that a Denadrips preamp and amp combo I see behind you ? Review coming up soon ? :)
Very intriguing, but you'd need two 8.5" drivers inside that thing to move as much air as a single long throw 12" driver. If KEF marginally increases the box size and puts two 8-8.5" drivers inside, I'll bite.
Glad it lived up to the hype!
Any thoughts on the sub shitting off at low volumes? It’s a criticism one sees . May be a workaround, but should work without imo
How does it compare against the REL T5i , would you buy 1 KEF or two T5i’s for the same price ?
I have the kc62 sub and kef lsx II and turned the volume up 60 percent and bass at 10 all the way. Played a song with lot of bass. Will anything get damaged? Or did it damage?
I have the LS50 Metas. I couldn't get the KC62s so settled for discounted Kf92a which are similar but bigger. I love the sound but my only disappointment is he doesnt explain his use of the speaker inputs and why he doesn't use the simpler other inputs . I am using LFE with the bluesound app which allows me to adjust everything. Am I missing out on something and not optimised?
Great videos!
Would you prefer this Kef setup (KC62 and LS50 Meta ii/LS50 wireless ii) OR an A500 Buchardt with hub?
I am asking myself the same question. Problem is the a500 is set to deliver only in August for new orders while the ls50w2 and kc62 are available now
@@Sinzbad I ended up getting the LS50wii with the kc62 combo and I'm super happy with the purchase. The app is a lotttttt better than the old one.
Would 2 of these be better than my 2 svs sb1000’s ? I have kef q550 front speakers and kef q250 Center speaker so would love to have everything match but price difference is quite a lot, which sound the best for home movies ? Cheers
Cool. Perhaps kef will combine both in a floor standing version?
That would be pretty sick
@@Zoranurai13 I would think so!
When you connect the subwoofer like shown, you have no high pass filter on the main speakers, and therefore they cannot play louder without distortion, although the extended low frequency may give the impression. Your amplifier does not have an easier load either. If you want to use the high pass filter on the line output, you need a second stereo amplifier to drive the main speakers, or you need active speakers with the sub. Thats not to say that the shown solution does not work, but you need to be careful with the integration between sub and main speaker, because there is no filter on the main speaker, you are just adding extra low level, that needs to fit with the slope and natural roll off frequency of your main speakers. The linearity will depend on the position of the sub as well, and phase adjustment is missing on this quite expensive sub. The dispersion from any subwoofer is omnidirectinal, so this sub is not better because of the two drivers in that regard. Even though they are omnidirectional, two subs are often a better choice, if you want good integration. Especially if you cannot place the sub in the center, and you are sitting a bit close to the speakers.
The Unicore feature may look fancy, but nothing comes for free, and the magnetsystems has two gaps, so if it is not twice the size magnet, you loose power (Bxl). The way you design a magnet system will influence the efficiency, so clever design can make a big difference. If the size of the magnet was a problem, they could have used neodymium instead, but that is more expensive.
The sub IS the high pass filter ....it removes the low frequencies from the signal going to the ls50 ....
@@edwardbalboa5528 now you tell me how that works... you would have to connect the ls50 to the Sub then, if it has an integrated filtered speaker output, which is definitely not the case... It would also not be a good solution by audiophile standards
I'm with Andreas here. The signal to the speakers and their load on the amp is unchanged using a high level connection. The speakers are still trying to reproduce the entire frequency range. It's just you get extra bass from the sub.
I just found the manual, and there actually is the most common 0 /180 degree switch for the phase on this sub, so that is ok.
or just use a mini dsp
Great review ! Do you think this combination works better / is equivalent than high end tower speakers (such as Dynaudio)?
LS50 META+KC62 vs. Buchardt S400 mk 2, which one sounds better?
Im curious if this tech will be used in a larger variant to replace the KF92. Do they chuf for a closed? I thought chuffing was only for open or ported designs. I would imagine that there is breakup due to diaphragm or suspension not being rigid enough for so much pressure in a tiny body.
I have the KEF LS50W and am looking for a subwoofer. Which do you recommend? I'm considdering these KEf KC62, KEF KF92, Rel T7i, Rel T9i, SVS SB 3000, or SVS SB 2000 Pro. I don't really care about home theater, only about music. I don' have a lot of placement options, that's why this small KC62 sounds appealing. But how does it compare to the bigger ones, like the SVS or the REL. (I just now also watched your review on the SB 3000 and wonder what your opinion is on this).
My room size is about 5x8 meters by the way.
If I may and if you haven't already purchased, I'm playing Tannoy Cheviots in a medium room with lots of good quality A/B watts. You simply cannot beat REL T/7i hooked via the HL Speakon connection. I have one and it exploded my soundstage and dynamics, which was already really good. Just astonishing. I want to improve my 2-ch music, I don't want to feel that chest-thumping electronica bass the kids like. The RELs do this the best. The KC62 is smaller, easier to position and also should be hooked using speaker-level connection (with 16-gauge wire). Properly tuned and placed, the KC62s are 80% of the sound quality of the RELs. The KC62 cost quite a bit more expensive than the RELs. With the KC62, you are paying for the "cool" factor, smaller size, and maybe a little more placement flexibility. Both are really good.
There is no replacement for displacement?
Which one you prefer?
Kef ls50 meta + KC 62
Or
Buchardt s400?
I'm always interested in somebody tearing apart active speakers and measuring the amp output and driver impedance etc. Without that I take the claimed specs with a tablespoon of salt.
Man this sub is crazy pricey.
why there's almost no review of KEF Reference 8B Sub? and how is it compare with kf92?
Did you high pass the main speakers?
How does the sub filter the crossover? When you used speaker wires as input, does it convert to digital, then filter with DSP, and convert back again? Or is it an analog filter?
This sub looks like devialet speakers. The two opposing drivers.
and the devialet look like kefs blade? lmao
Nice review. I use the LS50 so this interests me. The only thing making me think twice is the lack of high pass crossover in the sub to feed the Mata. It can't be a sensible solution to have the tiny LS60 driver still running full range along with the sub.
I'm guessing our hero has bass management somewhere in the mix. I wish he would have made mention of it.
High pass filters in subs compromise sound quality more often than not
How do run bass management if you're not using an av receiver? I have ls50s and to take advantage of the sub you would definitely want a cut off maybe 80 hz. There is supposed to be a lot of distortion in the ls50 bass.
I prefer speaker level inputs to line level with my REL B2
What's the best crossover + volume setting when paired with Metas? I'm driving them with a Hegel H190
How does it compare to a REL s/510 or REL T9i, for a music listener?
Hello my friend! I remembered that some time ago you reviewed the REL T5i sub. What is your thoughts against the KEF sub?
I love my REL T5i but this looks like it takes things to the next level, and looks so cool at the same time. Think it might be upgrade time!
I briefly mention in the review that I preferred the kef kc62 than 2 rel t5i.
It’s to bad that the two woofers cans be configured independently to be out in dipole mode (synced) to better integrate with the Magnepans. Face one forward and the other back, yes? Also, If it wasn’t for the sealed nature and shared cabinet, one could place the woofer between a pair of speakers and get a stereo effect from one unit. That would be interesting
@@Jayiyagi, thanks a lot Jay. Take care!
What about KC62 vs REL s/510? For music? For movies? Im using medium sized floor standing speakers
Hi...do you hav a video where you talk more about this preferred wiring method? I am not sure that I understand why you prefer this over the normal sub/signal output from an amp. Thanks.
How does the bass of this compare with the Devialet Phantom Gold?
did anybody noticed the chemical smell of the wireless 2? i have them for a week and when the speakers are playing and the amps getting warm the smell is like aceton?
Another major con is, no variable phase control. I guess I will have to pass on this sub because of this.
QUESTION: HI, I like your channel 😊 how did you connect the Kef kc62 sub to your willsenton tube Amp??
Thank you
Gabriel
Thank you for your videos. As a Bahamian we have to travel to Florida or NYC to demo gear. Can the LS50 Metas push sound 15/20 feet away in a home theater? I know they’re near-field monitors.
I'm new to hifi and bit confused about the ls50's sounding better after adding the kc62. You mentioned that the ls50's are less stressed as they don't have to produce the low frequencies. But the cross over setting on the sub impact it's own capabilities and cannot impact the ls50's. They will still try to produce all the frequencies unless there's a cross over in the chain. Would really help if you can elaborate, thanks.
I'm pretty new to this too congrats on getting into it. I think what he was trying to say is that the ls50s may go down to a certain frequency but they may not play those notes well. The bass may be muddy or just not as good as floorstanding speaker. A more than capable subwoofer would help fill in those gaps where a bookshelf speaker may not excel. Hope this helps.
There is a saying: "You don't know what you're missing until you've heard what you're missing."
In this case, adding the lower frequencies with a quality sub to a pair of quality speakers has a knock-on effect that reinforces and improves the frequency response throughout the entire frequency range.
If you have not heard this phenomenon in person, it's difficult to imagine. Thus, the quote above. As soon as you hear it, you understand instantly.
Well, perhaps not technically, but you know what you're hearing. : )
What he was referring to was passing the speaker signal through the sub where a high pass version of the signal is then available on another pair of the sub terminals, which is less demanding (due to the lack of bass signal), for what ever speakers are then connected.
In other words the sub splits the mid/high and low signals, and you connect your main speakers to the mid/high output (via a power amp).
Hope that helps!
How does it compare to the svs sub that you reviewed recently? I don't think you mentioned it in the video
Subs move air. The lower the frequency, the more air they have to move. The larger the room, even more air needs to be moved. 6.5" speakers need to have a huge x-max in order to move that kind or air, and I mean HUGE x-max. From what I saw, the drivers only have big x-max. That makes me think that they are doing phyco-acoustics to make the driver "sound" like a lot of deep bass.
How do you think they would be for theater room listening, do the have enough low end to rock a 13x20 room, using 2 of the KC62 sub woofers?
