”A brilliant, compact all-in-one hi-fi system”. ’What Hi-Fi?’ 2020 award-winner.

Compact speakers which do it all

Great-sounding and stylish, the KEF LSX speakers get off to a flying start. Yet, there’s more. Featuring built-in 2 x 100 watt amplifiers, Wi-Fi, AirPlay 2 and Bluetooth connectivity plus optical and analogue inputs, the LSX is a complete system in itself.

Truly wireless design
Unlike most active speakers, the LSXs are truly wireless. This means there’s no physical link between the speakers (operates with music files up to 48kHz/24-bit). If you want to listen to Hi-Res music up to 96kHz/24bit then simply use the supplied linking cable.

Spacious, stereo sound
With two speakers rather than one, you’re already off to the perfect start with broad, stereo sound. At their heart of each speaker is KEF’s Uni-Q technology. This places both drivers on the same axis, giving smooth, cohesive sound and an immersive soundstage. Enhancing this further is KEF’s Music Integrity Engine. This advanced technology corrects and adjusts the speakers’ output to deliver the most accurate sound with the least possible distortion.

Punchy bass
Featuring a dedicated, Class-D 70 watt amplifier for each woofer (plus a 2 x 30 watt amp for the top end), the LSX has got power to match the quality. Carefully matched to get the very best from the speakers, the amplifiers deliver smooth, punchy power to give these speakers the ability to get the best from all types of music. If even this isn’t enough, a dedicated sub output lets you connect your own choice of active subwoofer.

Wi-Fi, Apple AirPlay 2 and Bluetooth 4.2 – the wireless choice is yours
When it comes to streaming your music wirelessly, the LSX offers all the options. Stream through your network via Wi-Fi. Alternatively, use AirPlay 2 with your compatible Apple device to create a multi-room system that integrates with Siri. For the best quality Bluetooth connection, the LSX is compatible with aptX from Qualcomm – giving higher resolution sound from your smartphone or tablet.

Connect up your TV, too
Thanks to its optical and analogue inputs you can also connect up other sources, such as your TV, games console, CD player or turntable (with built-in pre-amp).

Easy control with dedicated app
Keeping this complete system under control is a dedicated app. Available for Apple iOS and Android, the app not only controls the speaker settings but also ties in with your stored music, media servers, Tidal and Spotify Connect (Spotify Premium account required), for seamless music streaming. You can also save and create custom playlists.

Choose your style
Available in five striking finishes, the KEF LSX looks every bit as impressive as it sounds. Choose from red, white, blue, green or black for a style that suits you. For a warmer look and feel, the speakers come wrapped in a luxury textile cloth from the Danish manufacturer, Kvadrat.

Hear the true sound, wirelessly, with the versatile KEF LSX speakers.

Rated 4 out of 5 by from Great sound, but not without issues. I wanted to downscale my set up consisting of separates, to focus mainly on streaming, but wanted flexibility of connecting different audio sources including an existing turntable with built in pre-amp. After expert advice from Brighton Store over email and the phone, KEF LSX seemed to best fit my needs and I bought a mint condition, open box product during lockdown. The sound is phenomenal - when set up and positioned correctly. They are set up around 1.7m apart on a shelf, either side of a TV and while they are not Dolby compatible, they have effectively replaced my Pioneer sound bar and 5.1 system and I've not regretted the change. Note - if connecting a turntable, make sure that you eliminate any potential ground loop feedback, as the 3.5 aux input is sensitive and generated a 60Hz hum when my Audio Technica TT was connected. Havinig tried a number of different solutions, including different power extension cables, external pre-amps and ground loop isolators, I have had to ground the TT to the metal ethernet input on the back of the speakers using a ground wire, even though this should not be needed because the Audio Technica has a built-in preamp. Second issue was discovered a couple of months after purchase - the secondary speaker developed a high-pitch whine when in standby. It was faint but loud enough to be annoying. On this point, I cannot stress enough how great Richer Sounds were in getting this problem fixed. They took back the speakers and sent them off to KEF who replaced the faulty part. All good so far. This would have been a 5 star review, had it not been for these issues, however, this was an open box purchase.

Rated 5 out of 5 by from Very happy with KEF LSX speakers and the service under lockdown I couldn't visit the store and hear the speakers on site. Richer Sounds gave me a home trial and this confirmed that I would be happy with speakers. I chose the speakers to reduce the number of boxes and wires. I stream the music from the cloud to the speakers using an app. The sound is just about right for the size of the room. The sound improves as the volume goes up but there are limits to what one can endure. I am a 98% classical listener. By writing this review I will be entered into some sort of raffle with the prize of a £30 voucher. This has not influenced my review or scoring.

Rated 5 out of 5 by from Superb sound quality The look and feel of these speakers oozes quality. And the sound they produce is superb, especially for their size. I have them set up for Airplay from my Mac and Bluetooth from my phone. The audio frequency range and clarity are excellent. Every detail in the sound comes through clearly and they are comfortable to listen to. When I first set them up and played some music my wife in another room came through and commented on the fullness and quality of the sound. Buy only gripe was the time it took me to get them set up. I had read reviews where some had commented the app was unstable. I didn't find it unstable, just not as straight forward as the user guide implies. A very minor point, the size of the labelling for the various sockets and connections on the back of the speakers is very small and difficult to read. It is not difficult though to work out what each socket is for.

Rated 5 out of 5 by from Excellent KEF Speakers I bought these wireless speakers for my 'music connoisseur' husband and he loves them. Immersive, crystal clear, top quality sound. Thanks to Dan at Richer Sounds, Southgate for getting the KEF LSX and KEF S1 delivered with 48 hours notice, when no one else was able to and in time for our 25th Wedding Anniversary. Excellent customer service and excellent Speakers

Rated 5 out of 5 by from Outstanding service and speakers I contacted the Newcastle store and spoke for advice on a wireless speaker system I was interested in the Kef LSX for listening to streamed music downstairs. During the lockdown, I couldn’t visit the store to listen to the speakers. This was a problem as I was spending a significant sum of cash on something before the demo and I have a particular sound signature I enjoy. The staff member was extremely helpful, honest, and accommodating. He arranged to send out a demo set (obviously I had to pay upfront) with the understanding that if I wasn't happy I could return them at RS cost and get a full refund. If I liked them they would arrange a courier collection and replace the demo speakers with a brand new pair. Exemplary service from th store and greatly appreciated. After the initial speaker set up via the Kef app I was soon listening to my music via Spotify and the sound was outstanding. I was hearing instruments in music I could not hear before when played through my Yamaha Soundbar or even my Bose wave radio. My previous AV setup was Kef orientated and I loved the sound but for many reasons, we changed to a soundbar system. I honestly had forgotten how good a high-end kit can sound. There is only one problem now and it's getting expensive. I want better headphones for my computer as I now know how music is meant to sound. Thanks

Rated 4 out of 5 by from Great speakers Bought this as an upgrade to the standard TV speakers and some connectivity to play music. Fantastic quality build and sound. Initial issues with setting up, but once sorted, been a delight to use!!
