Features

PURE

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.

KEF 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.


PURE

POWER

Dynamic, uncompressed and undistorted bass of heart pounding clarity envelops you, striking deep emotional chords. Your soul will awaken. And the earth will move.

BASS DRIVER

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.

POWER

PRECISION

Designed from the ground up, the 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.


PRECISION

SIMPLICITY

A little finesse goes a long way to delivering a big impact. Every aspect of the 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.


SIMPLICITY

ACCESSIBLE

Serious audiophiles can now enjoy phenomenally accurate reproduction that neither adds nor subtracts from the original recording. Indulge in a near THE 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.

Great Buy - SoundStage!
KEF's R900 is exemplary. Its sound is linear and coherent from bottom to top, offering more than a glimpse of what the best loudspeakers offer, and at what must be considered an affordable price. It has no real shortcomings, only an abundance of strengths -- and an emphatic recommendation from a writer usually allergic to such things.
