R8a Dolby Atmos-Enabled Speaker

KEF R8a Dolby Atmos-enabled speakers sit above your existing front and rear floor-standing 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. 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 center of a 130mm (5-in.) bass/mid driver and KEF’s ‘tangerine’ waveguide to maximize 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.


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.
