KEF Premium three way F/Standing speaker. 1 x 125mm MF, 1 x 25mm HF vented aluminium dome tweeter, 4 x 165 mm LF . High Gloss Black, PAIR
R11 is the flagship of the new R Series range. Boasting four 165mm (6.5 in.) hybrid aluminium bass drivers, R11 digs deep and retrieves an exceptionally clean and musical low-end performance. Nestled in the centre of these lies the new 12th generation Uni-Q driver array. The 125mm (5 in.) midrange driver and 25mm (1 in.) aluminium 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.

FLEXIBLE PORT TECHNOLOGY
When it comes to generating deep, articulate bass, port design is crucial. The ports in R Series feature innovative flexible walls. Using computational fluid dynamics, the flare and profile of each port are calculated to delay the onset of turbulence, while the flexible port walls prevent longitudinal resonances from colouring the midrange.
BEAUTIFUL BY DESIGN
Great design is timeless. KEF’s product designers seek to create deceptively simple, elegant loudspeakers. But form follows function. So whilst R Series is driven by acoustics, all visible engineering fixings have been artfully concealed so all the listener sees is a beautiful and simple exterior.
Conceived to be at home anywhere, the R Series comes in a choice of two sleek gloss finishes or a classic wood veneer. These finishes go deeper than just a base colour: each speaker benefits from KEF’s tone-on-tone approach where tweeter dome, driver cones, feet, spikes and KEF logo are colour-matched to the finish.
The R Series has been created to sound at its best with or without grilles. This microfibre design is a first for KEF and resulted in a design that not only looks beautiful but has a negligible effect on sound performance. All of the grilles are handcrafted and compressed with heated pressure from thirteen layers of composite material. The grilles continue the tone-on-tone approach: grey for the white cabinet, brown for the walnut, and black for the black. The grilles' edges are burnished in a similar way to fine leather goods and the overall effect is almost suede-like.
