Best Product 2019-2020 - High End Loudspeaker

" ...a slender speaker capable of a big, rich, room-filling sound packed with detail and delivering superb musical involvement, and with the style to ensure it looks every bit as impressive as it sounds."

The new KEF R Series has been completely re-engineered from the ground up. The only thing to remain the same is the name. Decades of experience and KEF's unbridled passion for music come together in the new R Series. Combining innovations from the Reference Series with bespoke technologies the new R Series delivers more detail, deeper insight and greater excitement.

The largest model in the R Series combines four bass drivers and the latest generation Uni-Q for a powerful and refined sound. With hybrid aluminium bass drivers and a 12th generation Uni-Q for mid and treble the mighty R11 is extremely capable. Using technology from KEF Reference it delivers clarity, finesse and serious bass.

Feel The Music

Feel The Music

When you want to forget the world and simply lose yourself in sound, R Series will take you there. KEF's quest to develop perfect loudspeakers has lasted more than 50 years. Like you, they don’t just want to hear music; they want to experience it and feel part of it.

Great For Movies

Great For Movies

In the movie world, the best sound engineers are capable of weaving ever more wonderful sonic webs and the new R Series is your ticket for getting the best out of movies, delivering the natural, consistent sound essential for a phenomenal surround sound experience.

Beautiful By Design

Beautiful By Design

Form follows function in KEF loudspeakers, so while the R Series is driven by acoustics all fixings are hidden, so all you see is a beautiful exterior. The R Series comes in two sleek gloss finishes or a classic wood veneer. The details are even colour-matched to the finish.

Microfibre Grilles

Microfibre Grilles

The R Series was created to sound its best with or without grilles. The microfibre grille design is a first for KEF and not only looks beautiful but has a negligible effect on performance. They continue the tone-on-tone approach to match the various cabinet finishes and the edges are burnished for a suede-like effect.

Shadow Flare

Shadow Flare

The Shadow Flare is an innovative way to cut harmful high frequency cabinet diffraction. It's a carefully profiled transition that extends the waveguide effect of Uni-Q. The treble escapes naturally because the ‘shadow region’ stops it getting to the cabinet edges. The result is vastly improved fine detail.

Cabinet Bracing

Cabinet Bracing

A solid platform is imperative for great sound. The new R Series benefits from Constrained layer damping. This system utilises internal braces joined by a ‘lossy’ interface and is highly effective at dissipating unwanted vibrations that would otherwise artificially change the sound and music.

Low Frequency Drivers

Low Frequency Drivers

R Series bass drivers have a two-part structure with a shallow concave aluminium skin atop a paper cone. Combine this stiffness with the cone’s unique geometry and you get near pistonic movement for punch and speed. KEF has also increased linearity in the magnet system which means more impressive and impactful bass.

Flexible Port Technology

Flexible Port Technology

When it comes to generating deep, articulate bass, port design is crucial. The R Series ports have innovative flexible walls. Using computational fluid dynamics the flare and profile of each port is calculated to delay the onset of turbulence and the flexible port walls prevent resonances from colouring the midrange.

Uni-Q Driver

Uni-Q Driver

The evolution of KEF's Uni-Q driver reaches its 12th generation in the R Series. Using simulation and analysis tools KEF’s engineers have been able to dramatically reduce colouration by cutting resonance in the tiny gaps between Uni-Q’s elements. The result is purer and more precise sound with stronger imaging.
