Welcome to a world of High-Fidelity sound that is true enough to touch. This all-in-one speaker system in its second generation: upgraded to deliver a more balanced sound in higher resolution with all-inclusive connectivity.

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.

Stereo. Feel the performance.
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.

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.

Connectivity
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.

Perfect partner for… everything
Sound plays a big role in your home entertainment and LSX II elevates the total experience with high-fidelity sound. Fully loaded with wired and wireless connections, LSX II is perfect for music, gaming, TV, movies and even your personal working space.

Plug and play to TV, laptop and more
With LSX II, you can connect your TV with HDMI ARC, your laptop with USB-C, and even a turntable, CD player or games console. If you demand your movies and music come with extra bass, there’s a dedicated output to connect a KEF subwoofer.
