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 R8a 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. Integrating perfectly with our R Series, Q Series and Reference Series aesthetically as well as sonically, the closed-box design of the R8a features KEF?s 12th generation Uni-Q driver array. With a sophisticated 25mm (1-in.) tweeter at the centre of a 130mm (5-in.) bass/mid driver and KEF?s ?tangerine? waveguide to maximise dispersion, it has excellent dynamics with accurate, fast and clean midrange response. And as the speaker footprint is the same, no more space is required.

KEF 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.

What is Dolby Atmos?

In real life, sound comes from all around. But conventional surround systems only allocate it horizontally ? left, right, ahead and behind. 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. The effect is uncanny. Exhilarating. Sometimes scary, sometimes hilarious; always engrossing.

How Does It Work?

How does it 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. Dolby Atmos has the ability to adapt to diverse speaker setup. You can enjoy the full effect with just seven KEF speakers.
