FULL REVIEW

Audio Performance. Visual Perfection.

A wireless system that delivers true stereo sound packed into a striking, compact design. The LSX Soundwave is crafted to satisfy those who know that design and music are just better when they come together.

Your music your way

The LSX Soundwave is all things to all music lovers. Spotify Connect and Tidal are built in so you can stream from the cloud, directly from an NAS drive or computer, or by simply using Bluetooth.

Apple AirPlay 2

LSX comes equipped with Apple AirPlay 2 to deliver multi-room audio. Use it to wirelessly stream your favourite music apps to your whole home with seamless control from your iPhone, iPad, and Mac.

The sound behind the vision

With truly immersive, natural sound, the LSX Soundwave proves it’s more than a pretty face. KEF’s signature Uni-Q driver array places the tweeter at the centre of the midrange and bass cone. This not only makes music sound clear and detailed, but brings it to life across a wider listening area.

Design that delivers

Encased in fabric created by Danish contemporary textile designer, Kvadrat the LSX Soundwave features a stunning soundwave pattern developed by Sir Terence Conran. Aspects of the driver, as well as the rear port, are finished in Conran’s signature blue; subtle details that assert a presence and personality to work in any space.
