DOLBY ATMOS FLEXIBLE SURROUND

The R8a works as a surround or rear speaker and can bounce sound off 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 130mm (5.25in.) Uni-Q array with a 25mm (1 in.) tweeter to steer the sound for genuine 3D results.

WHAT IS DOLBY ATMOS?

In real life, sound comes from all around. What makes Dolby Atmos so staggeringly realistic is that the movement of every sound in the scene is reproduced in all three dimensions, including vertically. This creates a true 3D acoustic image of precisely located individual sounds that move in relation to you as if you were actually there.

HOW DOES DOLBY ATMOS WORK?

Dolby Atmos is infinitely more flexible and adaptable than channel-based home theatre. When a Dolby Atmos stream is fed to a Dolby Atmos compatible A/V receiver, the receiver will render the object-based audio to your home theatre’s unique speaker configuration to precisely recreate the sound the filmmakers intended.

R8A WALL MOUNTED SURROUND SPEAKER

R8a can serve as a surround or rear speaker using the convenient mounting system built directly into the base of the R8a. Sleek and unobtrusive, the R8a makes for an excellent addition to any home theatre system.

KEF R8A DOLBY ATMOS ENABLED SPEAKER

KEF R8a Dolby Atmos-enabled speakers sit above your existing front and rear floorstanding or bookshelf home theatre speakers. Knowing how the brain perceives sound, KEF engineers have perfected a way of beaming the sound upwards so it reflects off the ceiling to replicate the vertical dimension in Dolby Atmos recordings.

UNI-Q

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.
