R50 Dolby Atmos-Enabled Speaker

Quick Overview

Designed to sit above freestanding or wall-mounted home theatre satellite speakers, the new KEF R50 adds the all-important vertical sound dimension that allows you to enjoy at home the staggeringly realistic 3D sound image that Dolby Atmos creates in cinemas. Built around KEF's latest and most sophisticated 'sit anywhere' Uni-Q driver array, with a 25mm (1-in.) vented aluminium tweeter at the centre of a potent 130mm (5.25-in.) bass/mid driver, it beams the sound upwards to envelope you in a breathtakingly precise multidimensional soundscape where each sound source moves as it does in real life.

R50 Dolby Atmos-Enabled Speaker

KEF R50 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 that it’s reflected by the ceiling to replicate the vertical dimension in Dolby Atmos recordings. Integrating perfectly with our R Series, Q Series and THE REFERENCE ranges aesthetically as well as sonically, the closed-box design of the R50 is built around the Uni-Q array developed for the revolutionary KEF BLADE. With a sophisticated 25mm (1-in.) tweeter at the centre of a 130mm (5.25-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.
