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.
Amazingly fast and clean mid-range response. Startlingly pure high frequencies. All operating as a single perfectly integrated voice to deliver sweet, accurate sounds of unprecedented clarity.
The new Uni-Q driver array is nothing short of a masterpiece.
Unlike conventional speakers, the mid-range cones are rigid magnesium/aluminum constructions that reduce breakup problems. The new mid-range Z-flex surround smoothes the tweeter transition to the front baffle, which results in undistorted high frequencies.
Large voice coils increase power handling and dynamics, reducing distortion and delivering exceptional vocal clarity.
Venting the tweeters reduces pressure behind the dome, increasing midrange bandwidth and lowering distortion. Upper registers are articulated with flawless precision. KEF’s tangerine waveguide helps disperse higher frequencies evenly across a wider angle to flood the room with a sophisticated, refreshingly natural sound field.
Dynamic, uncompressed and undistorted bass of heart pounding clarity envelops you, striking deep emotional chords. Your soul will awaken. And the earth will move.
Massive, vented magnet assemblies and large aluminum voice coils drive the lightweight yet stiff, strong hybrid cones. Bass output is faster, cleaner and more accurate. Satin anodised elements contribute to the unit’s elegance, while the diameter of the trim ring accentuates a visual sophistication that belies the speaker’s awesome power.
Force cancelling drivers avoid cabinet agitation. Opposing reactive forces are nullified by rigidly mounting the low frequency drivers back-to-back.
Designed from the ground up, the KEF R Series is a towering leap forward that creates a new dimension in sonic authenticity.
The geometry and bracing of the enclosure optimises vibrational behavior, reducing secondary radiation from cabinet walls for a cleaner sound. Damping panels further minimize cabinet resonance and colouration.
Front baffles are clean with no visible screws. Grilles are fixed magnetically. Available in real Walnut and Rosewood veneers, or highly polished Piano Black, the R Series complements the home as much as it respects the music.
A little finesse goes a long way to delivering a big impact. Every aspect of the KEF R Series has been considered in the creation of a superb audio experience.
Adjustable die cast aluminum feet support steel spikes, with integrated locking knobs for easy height adjustment. Nickel plated bi-wire connectors with terminal linking control allow all standard connection methods and provide easy, reliable connection.
The geometry of the reflex ports has been tuned to minimize turbulence at high levels, reducing port noise and low frequency compression.
The KEF R Series presents the high-end technologies of KEF Blade in a timeless, elegant format. Serious audiophiles can now enjoy phenomenally accurate reproduction that neither adds nor subtracts from the original recording. Indulge in a near-Reference experience at a price that will also be music to your ears.
Refined, spacious and exquisitely detailed, you won’t just hear music the way it was intended it to be… you’ll live it, feel it and love it.
