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.

Stereo. Feel the performance.

With two speakers positioned part 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'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 disperses sound more evenly, allowing everyone sitting at different spots in the room to experience the same natural, detailed sound.

THE PERFECT PARTNER...FOR EVERYTHING

Sound plays a big role in your home entertainment experience 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.

Same music, same enjoyment for every room

LSX II is more than a high-fidelity speaker system - it is designed to enhance your everyday life. Seamlessly integrate LSX II into your smart home to browse and play music, select sources, or use controls such as play, pause, and adjust the volume via your smart home app or control interface.

User-centred

INSTANT CONTROL IN YOUR PALM

The KEF Connect app walks you through simple setup and gives you complete control of what you play on the LSX II. It is intuitive to use with any source in your home, and it allows simple over-the-air firmware updates that bring you new and improved features with the minimum of fuss.

PERSONALISED LISTENING EXPERIENCE

Simple, subtle yet powerful EQ settings allow you to fine-tune LSX II to best suit your room or your personal taste. The only thing you might need is a tape measure.
