DSP and room EQ for accurate sound
Custom-tailored digital signal processing (DSP) ensures hi-fi performance. And DSP-based room equalization lets you answer a few simple questions in the free KEF Connect mobile app (for Apple® and Android™ devices) to tune the speakers to your listening space..
A wide "sweet spot," thanks to Uni-Q technology
The LSX II features the 11th generation of KEF's patented Uni-Q driver, which places each speaker's tweeter in the acoustic center of the bass/midrange cone. That lets the speakers create a detailed, accurate, three-dimensional sound image. In essence, it makes the "sweet spot" — the ideal listening position — much larger. Sit wherever you like! It'll sound fantastic.
