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.

Rated 5 out of 5 by PeteSt from Excellent stuff, very surprising. Only two days in but wow, a wonderful pair of tiny speakers! Chose these due to loving a pair of LS50 meta with Cambridge CX separates in the main listening room. Wanted something as good looking and good sounding for the office. In a small home office (3.5m x 2.5m) they sound huge! Surprisingly deep bass (honestly can’t imagine I’d need a sub, but you might in a bigger room) clean and clear highs and a very 3D overall soundstage. And they go loud! Everything played so far from 90’s hip hop, classical, classic rock and complex metal sound brilliant. USB from a Mac; sounds great. Tidal; amazing. HDMI for a TV for Xbox, yep. Lovely. Internet radio is as good as you can expect. (I’m using them wired together, not wireless) Great Kef app, Easy setup (listening to tunes in under 5 minutes) Bit pricey? Sure. But you really do get what you pay for. These sound like Hi-Fi, not a little pair of Bluetooth speakers! Big fan of my other Kef’s so might be a bit biased ;) but all those reviews can’t be all wrong, right?

Rated 5 out of 5 by Robw2 from Reach their potential when paired with a sub needing to spend more of my personal time at the desk I have been searching for something ‘good enough’ for critical listening at my desk. Kept coming back to the LSX since each speaker carries an independent amplifier and the integration with Qobuz Hi-Res is there. I listened at the MK store…with quiet acoustic pieces they were lovely but I was disappointed how quickly fell apart with polyphony. Gilbert recommended adding a sub to relieve the LSX of low pass bass. The difference was transformational when paired with the smallest Rel. All detail was restored on complex pieces and the sun gave the overall tone the richness of a bugger setup. Back home careful balancing of the sub and DSP settings they sound even better. Thanks to Gilbert I would have walked away had I not listened to them with the sub.
