”The bass is all thrillingly on point; lean and without any excess fat. You could almost call it superheroic.” ’Home Cinema Choice’ – Best Buy.

Small but mighty

At around 250mm in each direction, the KEF KC62 certainly qualifies as a compact sub. Using twin drivers in Uni-Core Force Cancellation configuration and powered by a 1000 watt amp, however, the bass performance is never anything less than mighty.

Uni-Core Force Cancellation delivers the power, without the bulk
Instead of using a large woofer, which inevitably leads to a larger cabinet, the KC62 is fitted with twin drivers, fitted back-to-back. KEF’s ingenious version of force cancelling uses a single magnet and concentric voice coils (Uni-Core), to deliver a mighty punch while reducing cabinet volume by over a third.

The power to impress
With 500 watts of Class-D amplifier power available to each woofer, the KC62 produces a mighty 1000 watts in total. This huge swell of power means that the bass isn’t just deep and loud enough but also kept under tight control, for maximum dynamic attack.

P-Flex surround for a smooth, even response
The KC62 is fitted with KEF’s P-Flex surround that’s designed to reduce cone movement resistance – especially at lower volume levels. This means you get a seamless response, without the ‘lumpy’ bass that can afflict lesser subs.

Smart Distortion Control
Using a powerful, bespoke DSP (Digital Signal Processor), the KC62 constantly analyses the signal for overloading, with SmartLimiter stepping in if needed to reduce distortion. Added to this, Smart Distortion Control technology uses current measurements to detect and correct any potential distortion. This reduces THD (Total Harmonic Distortion) by up to 75%, giving you a much purer bass response.

Adjusts to suit your room
As well as the usual volume, crossover and phase controls, the KC62 also features an EQ mode – giving you the best possible sound in your room. Choose between ‘Room’, ‘Wall’, ‘Corner’, ‘Cabinet’ and ‘Apartment’ settings for optimised sound in any setting.

A subwoofer you’ll be proud to show
Crafted from extruded aluminium, the KC62’s curved cabinet is in a different league to most other ‘boxy’ and bland subs. Finished in Carbon Black, Mineral White or new Titanium Grey, the KC62 deserves to be proudly on display, rather than tucked out of sight.

Enjoy the sound and sight of powerful bass, with the KEF KC62.

Rated 5 out of 5 by from Transformed Very good service from Derek and the lads in the shop on Deansgate Manchester. Arrived today and has added another layer to music that makes my naim and ls50 system sound like something much more expensive. Recommended

Rated 5 out of 5 by from Superb product and outstanding advice and service I have been contemplating getting this sub-woofer for some time, but was allowing the KEF LS50's I had from Richer Sounds to 'buren in' so to speak. Add the subwoofer and once again, the manifestation of depth, quality, detail and precision is enhanced an order of magnitude. Plus the KEF KC62 has so many ways to adapt it to the music and environment that it is beyond exemplary. Very pleased with the product and of course, also with Darren and Andy (sorry if I got your name wrong) at Richer Sounds. Just to be clear, I bought this item OVER THE PHONE, so, no option for that.

Rated 5 out of 5 by from Great subwoofer Very compact for a subwoofer but bass extension is excellent. Expensive but worth it.

Rated 3 out of 5 by from Sounds great at my friend's flat but not in mine I loved the sound of this sub when I heard it at a friend's house paired with the LS50 Wireless speakers. I have the LS50 Wireless II's so felt it a natural pair after enjoying the main speakers for over a year now. However I felt the sub was too boomy in my room, and had to turn the sub down to such a low level it was barely being worked and therefore felt overkill. Richer Sounds have been great throughout the process with advice and after sales support though I've returned this one and will need to rethink if I want to add more low-end to my setup

Rated 5 out of 5 by from Excellent addition to LS50 Wireless II Speakers I had thought for a while about buying the KC62 as an addition to the already good performing KEF LS50 W II active speakers I purchased a few weeks ago. With expected price rises affecting all walks of life, I decided to jump sooner rather than later. And have not been disappointed at all. A bit pricey, maybe, but this genuinely adds performance value to the LS50 W II that I have, more detailed, wider, taller & deeper sound stage. The 70Hz high pass filter option on the KEF Connect App' when used with the LS50 W II takes some of the workload away from the LS50's Mid/Bass driver, allowing them to be better used in the Mid range. I have a Tidal Hi-Fi subscription, lossless digital and into hires digital sound superb with 'Tidal Connect' functionality & MQA decoding & rendering built into LS50 W II's allowing direct streaming of audio digital to speakers, whilst allowing full control on smartphone via Tidal and KEF Connect. Genuinely listening and hearing a whole new world of audio when listening to music from times gone by.

Rated 5 out of 5 by from Impressive Together with the LA50 WII, they produce way more sound than my neighbours can handle :). The quality is truly outstanding. Super happy with my purchase

Rated 1 out of 5 by from Frustrating and ultimately disappointing. As always, the service from Newcastle Richer Sounds was phenomenal, and I'd not buy anywhere else. We listened to the KC62 with LS50 WII in store, then brought it home excited as the sound was outstanding, and this sub is tiny, well built and attractive. After a week of trying to work with the KC62, connected to LS50 wireless IIs following KEF's instructions, I couldn't live with it. Unless you manipulate the gain manually, turn up the volume (not always an option if you want to listen in the evening) or set crossovers to less than optimal frequencies in the KEF app, the sub won't 'wake up' from standby until 2 minutes into a song - and that was with a fairly bass-y track, at volume 30 in the KEF app. When you do get the sub to start playing, it will go back into standby during songs with less bass or if playing at under volume level 30 - making it a frustrating listening experience. Then, when you stop playing music, there is a low volume noise after turning off music until 10min later when the sub goes back to standby. Even ignoring the above, I couldn't get a balanced sound as there is so little adjustment to stop certain frequencies (resonances / reflections in the room / 'room nodes?) being too much, whilst other frequencies drop off and seem absent. The lowest frequencies are certainly there, but in my experience they were not balanced or at the same volume as the rest of the track. At this level and price, I expected to pair it with my LS50s and enjoy an excellent full-range sound. I spent a lot of time playing with positions, LFE/manual mode, crossovers on the LS50s / on the sub etc. Luckily for me, the amazing staff at richer sounds allowed me to try alternative subs from SVS and REL, and despite the massive price disparity - I've now gone SVS. I love the LS50s, but the KC62 isn't in the same league. At the price point, I expect to enjoy the product and for it to work well consistently, hence I have to say it is very poor value for money.
