Ooberpad brings to you the feature-packed 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 aptly 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 functionally 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 truly stellar dynamics with accurate, fast and clean midrange response. And as the speaker footprint is the same, no more space is needed.

Key Features:

  • KEF R Series R8a Atmos speaker with Uni-Q driver array
  • Ideal for surround speakers or elevation speakers in a larger home cinema setup
  • Uni-Q driver places the tweeter in the centre of the midrange driver for ideal acoustic placement
  • Shadow Flare profiled transition surface extends waveguides to prevent cabinet diffraction
  • Constrained layer damping dissipates unwanted resonances

            Benefits of KEF R8a Dolby Atmos-Enabled Surround Speaker:

            R8a Dolby Atmos-Enabled Speaker

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

            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.

            Uni-Q Driver

            The R8a speaker features KEF’s innovative Uni-Q driver array, where the tweeter is placed in the acoustic centre of the midrange cone. This brings the ideal solution of a single point source closer to realisation. The Uni-Q used in the new R Series is the 12th generation, benefitting from years of KEF’s refinement and development. The new Uni-Q driver has been designed using simulation and analysis tools, and reduces colouration by reducing resonance in the gaps between the separate elements, resulting in a purer, clearer sound with improved stereo imaging.

            Shadow Flare

            In order to minimise harmful cabinet diffraction for high frequencies, the R Series employs Shadow Flare technology, using a carefully profiled transition surface to extend the waveguide effect of the Uni-Q. The line of sight between the tweeter and the cabinet edges is no longer present, creating a shadow area at the places where the potential diffraction is highest. Reducing this diffraction helps to improve fine details, such as the subtle nuances of plucked strings and percussive sounds.
