The complete hi-fi system
Class-leading sound and style make the KEF LSX II wireless speaker system hard to beat. With AirPlay 2, Chromecast, wi-fi, Bluetooth and a wide range of inputs sockets, these wireless KEF speakers play everything you’ve got. Thanks to their 200 watt power output and the latest generation Uni-Q speaker system, they play it loud and clear, too.
The stereo advantage – made wireless
With two speakers rather than one, you get a much more immersive, three-dimensional sound. KEF’s Uni-Q speaker technology combines with their Music Integrity Engine for superb sonic precision, pinpoint accuracy and the least distortion possible. For music files up to 24-bit/48kHz, you don’t even have to physically link the speakers, making them wireless in every respect (a linking cable is supplied for listening to Hi-Res music files).
Made for High Resolution music – including support for MQA and ROON*
Designed for music lovers, the LSX II supports a wide range of High Resolution formats. With support for DSD and PCM music files up to 24-bit/384kHz, you get breathtaking detail and realism. MQA (Master Quality Authenticated) – as used by TIDAL Masters – is also compatible. ROON Endpoint status means it’s compatible with the award-winning music player – including Hi-Res files.
*ROON Ready expected via update late 2022.
Power to impress
Spreading an impressive 200 watts of power across the individual speakers, the LSX II have to oomph for effortless, room-filling sound. Carefully matched to get the very best from the speaker’s drivers, the amplifiers deliver smooth, punchy power that suits all types of music. If you’ve got a larger room or just want the ultimate bass, a subwoofer output lets you connect your choice of active sub.
Your music streaming, your way
Connect to your network via wi-fi or Ethernet and stream your music the way you want. Compatible with AirPlay 2 and Chromecast, the system suits most Apple and Android multi-room speaker systems. If you prefer to stream from your own music storage, UPnP (Universal Plug n’ Play) compatibility means it collaborates with a wide range of third party apps for effortless music network streaming.
Music streaming services and Internet Radio

Rated 5 out of 5 by Simsbsims from Beautiful looking speakers that sound great First off amazing service from Richer Sounds; ordered in the afternoon and delivered the next day as promised. The speakers themselves have a lovely finish and too me look great. Masterful packaging to which properly protects the product, is easy to get into and is fully recyclable. The important bit - the speakers sound great - I’m streaming from Amazon Music (paid for account therefore with HD content) and will try Tidal but definitely not disappointed! Connectivity on the speakers is great although I’m not actually using what is available. The Kef app seems good so far and no issues getting it to do what I want and setup was easy. My only gripe is the remote feels a bit cheap. I don’t really need to use it but if I do it is a little underwhelming; especially given the look and feel of the speakers themselves.

Rated 5 out of 5 by markfinch100 from KEF LSX2 Not only are these active speakers bangin, the quality of service from Richer Sounds is, as always epic! The sound stage is brill, the sound feature which impresses me the most is the scale and depth from such small speakers. Thank you RS, always a pleasure purchasing from you AND 6 years warranty thrown in!

Rated 5 out of 5 by Simonides from KEF LSX II - streaming music is easy, and fantasti Unti last week I was an old die-hard hard-wired stereo sort of bloke with a large collection of cds and a huge collection of songs on my pc. But no great way to listen to them - especially as my wife has insisted the new kitchen has no cables or wires or aerials. Solution? Richer Sounds - for a great demo of the speakers, and the knowledge on how to get the best from them. I was thinking of bluetoothing them - until Robert in Reigate explained what a NAS is and how streaming wi-fi will produce a great souns. Behold! All is set up in our living room and I knew instantly that this is the best music setup I have ever owned. From Focus to William Byrd to Genesis to Bach, the depth of sound, the clarity, the breadth of musical range is just superb. I was tempted by the next level speakers, but for our size of room, these are ideal (see KEF's own site for details). One last thing - Robert suggested some Denon Home speakers for the new kitchen, and I will be buying them in a couple of weeks! Where from? Silly: there's only Richer Sounds when it comes to listening to music!
