That’s the difference this channel makes:, not only review the product but demonstrate the technical “ setup” aspects of the hobby. Well done

Good review John. And what a package of hardware. The ls 50 wireless and the kc integration is fantastic.

An absolutely wonderful exploration of subwoofer use in stereo listening environment. I have been missing a subwoofer in my system and this has kind of convinced me that I need to get one.

I'm excited to see you love this sub as much as I do. I have it hooked up to my LS50 wireless at my desk. Love it more and more with every listen. Great review sir! Keep 'em coming.

Amazing content with so much effort describing what actually happens. I've kept my eye on the KEF sub since it was introduced. Thank you for most excellent guidance!!

John thank you so much for posting this video. I've been struggling to dial in my LS50W's with my Kube 8 for years. Countless articles and videos read and watched. But your video was exceptional in that you give a technically detailed but plain English explanation. This is why you are the best KZfaqr in this category. Keep up the good work mate.

Well done. The unique way John was a newb to subwoofing is very valuable viewing the topic from a more focused 2-channel music loving audiophile point of view. Doesn't hurt his first subwoofer is a too rare breakthrough product bringing true advances that are as user friendly as present state of the art allows. Well done John. Well done KEF.

Brilliant review, absolutely love your work! Based on the info in this video i will certainly be pairing up this sub with my LS50 Wireless II speakers.

Excellent review, probably the best most simple, straightforward and honest I’ve seen in ages :)

Thanks for the review. Very informative with the right amount of technical info. No overload of tech info. Excellent description of sound integration and considerations with an audio system. This was my 1st 'Darko Audio' video and will definitely watch others.

Instantly level up my system after seeing this in app kc62 setup for the wireless II. This feature wasn’t available when I first got the sub. Most practical video to date.

The review with the wireless 2’s I’ve been looking for, great in-depth review 👍🏻

Thank you. So many people like me who watch all of your videos, appreciate your approach and insight, but rarely comment. Please know we really enjoy your content!

Your experience mirrors mine with the LS50WIIs. I also use the wireless transmitter. “You’ll never go back.” So true.

Great review! I added a REL to my open baffles 5 years ago and truly believe my obsessive speaker flipping habit is over....5 years on and it's not once crossed my mind to change anything in the system.

I watch these religiously for several reasons. Great reviews, great visuals, and I usually learn about some cool music. They’re also quite relaxing videos to watch. Keep it up!

Thank you for these videos, Darko. I've been in dire need of upgrading my deftech studio monitor 55s. I've been leaning towards kef's wireless ii and you videos have made it an easy decision. I'll have my wireless iis and kc62 in about a month's time and I'm so hyped. Thanks again for your informative videos. Keep it up! 👍

I love how every other review said it was super easy to set up. Somehow I feel like Darko's experience is a little closer to reality.

A lot of two channel audiophiles discount the importance of adding hi-pass filtering to their main speakers, all too often to the detriment of their system. I'm a big believer in hi-pass filtering of the main speakers for proper sub integration, and this video did a really good job of explaining why that matters. Well done.

John, interesting to see your honest and enthusiastic reaction because you're an audiophile who hadn't experienced subs before. There are audiophiles out there who don't "believe" in subwoofers. Never understood it. Luckily you're a young guy and now have years ahead of you to re-enjoy music you already love, and new music coming your way.

Great review, thanks. Can imagine the sound and the perfect integration. You are able to cross over quite low, good. I think every bookshelf needs a sub for sure. I always use one makes a big difference.

great review. it's amazing how introducing a sub changes everything. I keep mine under my bed - best decision made!

One of your best videos John. Brilliant analysis on active vs passive setup. Great work 👏

After years and years of denying the benefits of a sub, because I was already happy with the sound of my speakers (middel range Tannoy), I bought one last year. And now, I couldn't live without it. When well adjusted, the music sounds so much better.

That's why I'm in love with the Outlaw Retro Receivers. They're designed for 2.1 setups and they high pass filter the stereo mains.

I hardly noticed that this video took 30min of my life. Awesome the way you explain things. Great video, again, John!

It's so true. Once you've intergrated a sub (or even two) you can never go back to living without one. Fabulous explanation and review John.👍

May I say, I truly appreciate the effort you put into your reviews and your ability to clearly convey your findings to us viewers. I'm currently saving up for the wireless 2's ( £1400 in the pot so far) and will definitely be looking at the kc62 to accompany them soon after (gotta get some more overtime in 😅) Thanks again for the work you do 😎👍

I'm so F Happy! I was debating getting the A500 or the LS50 II with the sub. After listening to the Kefs without the sub in the store I took the gamble and bought them with the sub in backorder. And a day later you will come with this review. Couldn't be more happy and sooooo keen for the sub arriving at the end of this month! (Hopefully) Thnx!!

I had a similar experience with my lowly KEF LS50 I and a lowly Yamaha S2000 integrated, and a lowly cheap Pioneer Sub designed by Andrew Jones. It is a pain in the butt to dial in the sub, but once it is dialed in, I can never go back to just the speakers. Now I'm running 3 subs in the room, only draw back is, if I make some change to the system, I need to fine tune the 3 subs all over again, but to me, the reward is worth the effort. Thanks John for this great review, it confirmed a lot of things I experienced with proper speaker sub and room coupling.

The improvement in midrange was noticeable using a processor/avreceiver as Xover spliting speakers/sub when someone convinced me to use a sub for music/hifi more than 10 years ago... it improves sound and leaves more power/dinamics to the speakers. You made me want to get my sub that I stored away after moving to a smaller room a few years ago! ;) That KC62 looks awesome!

Cracking review, 100% concur - Have got the KC62 with the original LS50W and the space and detail it allows the 50’s to go to is insane. Lends weight not only to the bass but also to the mids. Cannot go back to without. FYI I have mine in a open fronted cabinet and even still it’s unbelievable thump. Try T-Rex - Life’s a Gas and you will hear lows that didn’t exist before. Keep up the good work! 👍

Great video! I've always avoided Subwoofers because I just didn't understand how to set one up without ruining the balance of my system, but this video really helps explain everything!

Amazing overview. Thank you. Patiently waiting for mine to ship.

Really excellent review. It also answered some questions about integrating with both low and high pass filters. This really makes me consider adding a sub with the Dirac feature in my amp.

Really like your reviews. Long term Engineer, I have always been interested in Audio. Your reviews are interesting, especially how you take complex subjects and explain for an audience with wide ranging understanding in audio technology. Entertaining. Well Done !!!

Great review (as usual). Anyone who's spent time setting up high-end automotive audio has lived the (perceived) increased soundstage with high pass filtering. We don't perceive the directionality of low-end signals so when they're coming from a full range it adds to a strong center presentation. Remove the low end, and things open up!

Damn John. Ace of Spades. The only thing for me better than your nailing the holistic expanse and depth in the review, as well as the more refined and nuanced explorations, is the passion you convey (and that goes for your others as well). Your music reference has turned me on to some new good stuff too. Just ordered new passive Metas, seeking a proper 100W amp for them and looks like this will be added to the upcoming Xmas/bday self love gift.

Thanks John, for a great review. It’s so satisfying to finally hear a reviewer articulate the benefits of a high pass filter on the main speakers! Most of the other popular reviewers that I follow have drunk the REL Acoustics kool aid! One of them who I highly respect,even thought the idea of a high pass filter was too complicated! Can you believe it?! Here’s the thing that totally baffles me that you eluded to. So, so many of the options for high(er) end integrated amplifiers don’t have main amp inputs! Not your $5k Hegel amp! I find this *crazy*! Even the mid-fi manufacturer NAD used to have this as a standard feature on all their integrated amps, going back at least as far as the 3020; but not any more! Why on earth not? Why is this now the exception rather than the rule?? Thanks!

I think people will truly appreciate the addition of a sub now. Its literally a whole new experience.

So fun to see Johnny experience a sub for the first time! Love these vids.

Your videos are the best! Thank you and it's great to finally be able to tell you that.

Thank you very much for his excellent review, gladly I recommend my brother earlier to buy this speakers and I’m glad also to his satisfaction . Keep up the good work 👍

Superb review indeed, great explanations for us who are more interested/have more knowledge in music (than gear/specs/measurements), but want a great sounding system! Great music choices/examples and the changing weather just adds atmosphere 👍

Well done, one of the best reviews I have ever heard or seen of hifi gear. Do not change your presentation, it is perfect. it is almost as if we are siting together and solving the set up and discussing it on a one to one basis in my room. The only thing missing was a cup of tea and a biscuit!

Great content thanks a lot. And not one mid-roll. You’re my hero dude. I am using my Canton Sub 601 (also real small and stunning sound and build quality/look) with my Dynaudio excite x34 and the sub had such a significant impact on the sound. Its unreal. Especially concerning the mids and highs and soundstage depth. It now comes seriously close to my friends contour 3.0. Respect and stay healthy.

That bark is cool! Excellent video and audio editing! Congratulations!

Excellent review and a great explanation of subwoofer integration. I’ve just bought a pair of REL T9is and having a right challenge working out where they need to be placed and configuring settings. Subs are very definitely not just plonk and play. But hey, that’s the fun of this hobby!

🔥👍🏾👍🏾Enjoyed this video, now on your later trial with utilizing the high pass crossover, that's where I've always felt that upper range speakers do their best and really shine especially in conjunction with a subwoofer properly set up. Thank you for really pointing that out I've been telling fellow enthusiasts that for years and recently I've convince a few once they've heard comparisons for themselves

Really interesting, informative and enjoyable video. Thank you. Never really understood all the challenges in integrating a sub, but at least have some understanding now. Must have been incredibly difficult to put forward and explain all that information in a 30 minute video!

Excellent video John, thank you for opening up the world of subwoofers to those of us who’ve previously discounted them as Home Theatre kit....time to seriously consider introducing into a 2 channel system. Cheers.

I’m glad the comments are back, i hope you’re doing well John!

The first 10 seconds are the best. Well played John, well played.

This may be your first subwoofer review but it was an excellent one. I enjoyed it very much it was both clear and informative. Keep up the good work.

Really enjoyed this. I tried to integrate my old SVS SB sub which is a compact sub with my kef LS50W but in the end decided to leave the sub out. I have spent many hours in the past with a home theatre system using room equalisation wizard and a SPL meter to integrate a sub with mixed results. As others have said a second sub makes it a lot easier

Great to see you finally got a sub woofer. You will gain a new appreciation for drum and bass now.

I still have a 20 odd year old REL Q150. Your explanation of how to tune it in is spot on. I'm surprised with this sub that they do not recommend using the speaker connections in parallel with your speakers as this means the sub is receiving the same signals as your speaker. REL have been doing this for years and it works wonderfully especially if you run it to underpin your main speakers and also yo supply the LFE for AV at the same time. Once you've heard a proper setup sub there is no going back I'm afraid.

Another great review! Have been looking forward to this one.

i have had the same experience, i just got the Arendal 1961 1s, and my Genelec just lifted. The whole sound became better, more, bigger and easier to listen to. REally took me by suprise. In a very good way.

Sold, I purchased the wireless 2 in red on the back of one of your prior videos and was pondering the sub and this overview has persuaded me.

Ha! I came to exactly the same conclusions. Uniti Atom, LS50 meta, KC62 in the middle between them. Crossover at 50 Hz. And it does fill exactly what i always felt was missing. It added so much more fun to Hip Hop, Trentemoeller and even an opera. Thank you for this great story 🙌🏼

That was really interesting, thanks - I've been a sub user for years, and yes, it's hard work setting them up. The mid-range effect you found with the LS50 Wireless is interesting too, and is just the same as I found when I first had a system with an active xover and sub - taking the lower bass off the mid/bass driver seems to just take the pressure off it and opens up the midrange.

Seeing someone get a sub fills my heart with joy.

Liked the music selections today - look forward to the playlist on Patreon👍

My very first subwoofer was a micro subwoofer from Creative Labs that came with a Gateway computer back in 1998. I now have 2 subwoofers, a sealed studio subwoofer for my nearfield monitors and a ported subwoofer for my midfield living room setup. :)

Great and informative video, particularly around the topic of proper setup. Thanks! (I run a pair of LS50 wireless in my bedroom, and really like them)

Super helpful, thanks. I've bought the complete LS50 II system along with the KC62 sub. Opted for a wired connection twixt speaker & sub. Funnily enough, without even seeing this vid first, or turning the sub on, my speaker layout is where you've ended up at.

Thanks for the video John. I've learnt a lot from your channel (I've even built a RP4 following your instructions and used an Allo DigiOne hat, which is great btw). I've actually ordered one of these KC62s - I can't wait to dial it in (so to speak) and experience it for myself. Cheers!

My KEF KC62 arrived this Tuesday. Today is Friday and I think I have it where I like it. Because of its small size, I did try it out centered between my KEF towers (1995 Reference 3) but after listening to it for a day or two, it lacked the punch I was used to. This little KEF sub is replacing a 12" Velodyne that I've had almost as long as the Reference 3 speakers. My room is about the size of Mr. Darko's and the big Velodyne left me with two options: left corner or right corner. It ended up in both spots over its 26 year lifespan. For like 10 years it was in the left corner. After a repair needed to be performed on it, I stuck it in the right corner. But a couple years after moving it into its new position, I had sliding doors put in between the living room and dining room (just to the right of the sub), effectively closing off the room. This change really boosted the bass. I liked that. I got used to that sound. But when the Velodyne died two week ago, a new sub was needed. I read about this KEF mini sub and decided to try it out. Mainly because I want to keep the old Velodyne where it is so I didn't need to tear apart the room to get it out of the corner AND because it has been doubling as a stand for a CD tower. So when this new little beast arrived and I centered it up in the middle of the room, sure, it sounded OK. But there are a few songs that used to go down DEEP at certain points in my old setup that weren't doing that any longer. Was it because baby KEF couldn't match the huge, old Velodyne? NOPE! Once I moved it in front of the Velodyne in that right corner, all the deepness returned. In fact, it might be even deeper right now. This is probably because I have the volume set higher on this KEF compared to the Velodyne, but whatever. The KEF KC62 WILL rumble a modest-size house like a big sub can. If you don't mind pictures on walls going crooked, then give this subwoofer a try.

Great video, as always! But now I’ll be spending all afternoon experimenting with positioning my subwoofer! Fun stuff!

One of my most anticipated and most enjoyed of your videos, John. Well done. Great complement to the podcast, too. I hope KEF send you a second KC62 so you can try out a 2 subwoofer system. Of course, that'll mean another week of the "subwoofer crawl". :-)

Great review, I changed my mind about subs, thanks. Is not just adding bass presence, it's changes the whole image stage with the Kef KC2!!

Marvellous, deeply enjoyable video. Long time sub owner here so lovely to see experience it fir the first time :)

Cracking and informative review. I have two subs in a HT/ 2 channel music set up running through a AVR and, yes, getting the subs set up correctly is a bit of a faff. But when done right, changes everything. Thanks John.

After setting up your sub to where you want it, make sure you put white out on the dial to mark those perfect settings in case they get bumped. Great vid. Glad to hear such a tiny sub works well for you.

I absolutely LOVE your reviews, so honest, so down to earth, so humble... don't ever change 🙂👍

To entertain and inform. Great work John on both counts. Greetings to you and yours

I own a pair of Magnepan 1.7i and I was in lack of bass slam denial for a while. Well I finally got a pair of REL T/9i subs. That changed everything in an outstanding way. It truly revolutionized my Maggie system. More than any other tweak, cable or other component could do. IMO subs are mandatory with Magnepans. Like you said, John, once you try the sub(s) be prepared to keep them. You won’t want them to leave.

I got a lot out of this review, thanks. I have a different (non-Kef) setup but so much is useful and transfers over. The placement, crossover approach, active vs passive speaker considerations.

Welkom in the world of sub, I've been playing with them 20 years. Can't miss them in my stereo. Nice review John great one, thanks.

Fantastic video! Subs really do make a difference when integrated properly. I can only imagine what they will do to your Wilson's

The review I have been waiting for!

Great review. I've just ordered the KC62 as an addition to my LS50WII (on S2 floor stands) all in mineral white.

I have just introduced a pair of JBL-100’s into my home theatre room where there is a Klipsch SPL-150. At the moment the sub isn’t in play for two channel but I may have a play this holiday weekend. This channel is costing me dearly! JBL’s, Meze and door stops!!!

Great Video. Im from Germany. I've bought a KC62 to. My Setup are LS50 Black Edition with a NAD c368. I love it so much. But now with the KC 62 it's incredible. Stay on. Listen Music 🎶

Thanks for this video - it was very informative. I’m currently putting a system together consisting of Technics SU-G 700 (when I can get one), BlueSound Node, Technics SL1200GR (already have), and the KEF LS50 Meta. I was thinking about adding a sub at a later date so this has been really helpful to watch.

The biggest points you make regarding set up is still valid for larger subwoofers too. While a larger subwoofer can get much louder, for rooms or spaces that require it, it's going to be that much more of a task to set up and adjust as time goes on.

Thanks for this awesome analysis Jean Reno. 👌🏻😀

Ah finally someone using Trentemøllers `Evil Dub´ for testing. I use it everytime I listen to new gear (Hint: `Nightwalker` is excellent too)

hey john, why do i keep shazaming all your wonderful intermezzo's and throwing them in my qobuz favorites, combined with a perfect mix of technical / human experience / emotional feeling with all the stuff you review it's a real joy to listen/watch your channel

Great video! Very useful/informative. Thank you!

I recently used a subwoofer to solve an issue with bass boom (room mode issue) with my speakers playing at full range, it may sound counter intuitive using a sub woofer to solve a bass issue but it can really help, especially if your speakers are stuck against a wall in a small room (welcome to UK living!), using a high pass filter of around 70-80hz is a good place to start, you don't really want to go much higher than that otherwise you can start to hear where the bass is coming from.

A letter of thanks just sent to the Epsom branch of Sevenoaks HiFi: Good Morning Epsom SSAV Just a few lines to thank you for the extremely prompt delivery of my new KEF mini Subwoofer. As you can see below, now installed and fully operational. An absolutely doddle to set up, and even fresh out the box with no running in, already giving superb results! I have been listening this morning to various organ works CDs and suddenly the big pipes come to the fore, sounds which you feel rather than hear! I have by trial and error, found for the ATC SCM40 speakers that cut off at 50hz and volume at 11.00 o’clock are the best settings. The Tri amped ATCs already provide wonderful hefty bass, but the little KEF adds the cream of sub bass to the menu. At this moment listening to the 2011 remastered Dark Side of The Moon and the difference is stunning, with track 3, On The Run, one has become aware of the sub bass which now plumbs new depths. The little KEF definitely defies the Laws of Physics, such sound should not emanate from some thing so ridiculously small!

Finally! A proper review of this sub. Thank you, John. Other KZfaqrs have told us how great it is but not really discussed it in detail. I am floored by what KEF has done. This appears to be a serious piece of kit. Does it have good cone control? I'm guessing yes. Once you had it properly situated, did you tweak the settings from track to track or album to album? It would be difficult for me to leave the app alone.

Hi John great review, I have the LS 50 ii actives and I’m also a virgin but on seeing your review I’ve decided to relieve the tension 😉👍 and become a player, can’t wait to hook up the KC62 and here the results.😘

Thanks for the review John

Small and mighty. I like it.

Good one John, very informative to people who are also subwoofer virigns. And as you said, any decent sub once dialled in and locked (I did mine with REW) you can never go back :-)

Welcome down the sub rabbit hole. Great review! Have KEF send you a second unit. Like you said, living without a sub now will be tough. Once you try two, you will feel the same compared to going back to one. Stereo subs rule!
