KEF R8a Meta Dolby Atmos Speakers Black

Dolby Atmos Flexible Surround

The R8a is a two-way surround or rear loudspeaker in the KEF R Series. It can bounce sound of the ceiling to create truly cinematic scale with Dolby Atmos.
The flexible R8a can be wall mounted or placed on another speaker for Dolby Atmos height. It has a 130 mm (5.25 in.) Uni-Q array with a 25 mm (1 in.) tweeter to steer the sound for genuine 3D results.
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
In the movie world, the best sound engineers are capable of weaving ever more wonderful sonic webs and the R Series is your ticket for getting the best out of movies, delivering the natural, consistent sound essential for a phenomenal surround sound experience.

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.
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.

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.

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
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.

Cabinet Bracing
A solid platform is imperative for great sound. The 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.
