-KEF R Series R8a Atmos Speakers

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 12^th 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.

Cabinet Bracing

The cabinet bracing for the R8a uses constrained layer dampening to provide a solid platform for producing great sound. The damping has internal braces joined by a lossy interface, and is highly effective at dissipating unwanted resonances and vibrations that could alter the sound of the music.
