R11 is the flagship of the new R Series range. Boasting four 165mm (6 in.) hybrid aluminum bass drivers, R11 digs deep and retrieves an exceptionally clean and musical low-end performance. Nestled in the center of these lies the new 12th generation Uni-Q driver array. The 125mm (5 in.) mid-range driver and 25mm (1 in.) aluminum dome tweeter combine to deliver an even more natural mid-range and treble than believed possible at this price point. The result is a speaker that can pick out the softest details with grace and refinement, as well as deliver raw power and strength.

KEF’s groundbreaking Uni-Q driver arrangement operates by housing a discrete tweeter in the center of the mid-range (treble/bass) unit. This allows both the entire sound field created by the speaker to originate from a single point in space, meaning every sound in the entire spectrum reaches your ears with precise alignment. This produces a truly natural sound; a sound capable of convincing the listener they are hearing a live performance. Because the audio originates from a single point, you can stand anywhere in the room and hear performance more precise and realistic than other speaker can provide.
