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.

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.
