The Definitive Compact Wireless HiFi

The LSX II delivers High-Fidelity sound so rich it feels true enough to touch. Powered by cutting-edge audio technologies, including our KEF signature Uni-Q® driver array and Music Integrity Engine, it creates a soundscape that is both immersive and perfectly balanced.

Performance

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 dedicated amplifiers 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.

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

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 times performance with clear, accurate and more balanced sound.

Uni-Q technology is the building block of KEF's 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 dispersess sound more evenly, allowing everyone sitting at different spots in the room to experience the same natural, detailed sound.

Connectivity

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.
