KEF R11 Hifi Speaker (Pair)

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.) midrange driver and 25mm (1 in.) aluminum dome tweeter combine to deliver an even more natural midrange 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.
