KEF LSII Wireless Hi-Fi Speaker System


High-Fidelity Sound

KEF is obsessed with bringing a superior listening experience whatever the size of the speaker. With built-in support of streaming up to 24bit/384kHz and a dedicated amplifier inside each speaker, LSX II offers the highest quality sound in its size and makes high-fidelity sound accessible to a wider range of listeners.

KEF LSII Wireless Hi-Fi Speaker System


Stereo. Feel the performance.

With two speakers positioned apart of each other, the LSX II creates a three-dimensional sound stage of true stereo sound that brings your favourite tunes to life for a listening experience that a one-box speaker cannot come close to.

Small speakers, big sound

LSX II is upgraded from the first generation to deliver a more balanced sound in higher resolution. It is precisely tuned with enhancement on the bespoke Digital Signal Processing algorithms in the Music Integrity Engine (MIE™). Optimised for the Uni-Q driver array, the MIE ensures a perfectly timed performance with clear, accurate and more balanced sound.

Sit anywhere, hear every detail

Uni-Q® technology is the building block of KEF signature sound. Designed to perform at its best in LSX II, the Uni-Q driver array acts as a single point source to enlarge the ‘sweet spot’ and disperses sound more evenly, allowing everyone sitting at different spots in the room to experience the same natural, detailed sound.


All the music in the world

The advanced W2 wireless platform of LSX II ensures that no matter how you like to listen to music, you can do so with the minimum of fuss and in pristine sound quality.
