THE UNI-Q
LSX features the patented Uni-Q driver for crystal clear audio reproduction no matter where you
are situated.
The new 4” Uni-Q driver array is the same signature KEF technology used throughout KEF’s
speaker line.
Uni-Q has been in constant development since 1988. Through precise positioning of the drivers, all
frequencies are produced from the same point in space.
The effect is an amazing spread of sound. Uni-Q eliminates the tiny ‘HiFi sweet spot’ that only
allows one or two listeners to hear the music in its highest quality. Coupled with an extremely
natural response, the beauty of the sound is enjoyed equally by everyone in the room.
