KEF Bookshelf Speaker. Dynamic , unconpressed & undistorted bass. Bass driver with massive vented magnet. Uni-Q array: 1 x 1" HF & 1 x 5.25" LF/MF drivers. Colour Black. SOLD AS PAIR

The KEF R100 is a masterpiece in miniaturisation. Fast, clean and agile, with a low-end performance you would expect from a speaker double its size or with a dedicated LF driver, the R100 has a brilliantly designed full range Uni-Q driver array that makes the smallest R Series bookshelf speaker an astonishing performer.

 

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 midrange cones are rigid magnesium/aluminium 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.

 

POWER

The 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 aluminium 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.

 

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 optimise vibrational behaviour, reducing secondary radiation from cabinet walls for a cleaner sound. Damping panels further minimise cabinet resonance and coloration.

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.

 

SIMPLICITY

A little finesse goes a long way to deliver a big impact. Every aspect of the R Series has been considered in the creation of a superb audio experience.

Adjustable die-cast aluminium feet support steel spikes, with integrated locking knobs for easy height adjustment. Nickel plated bi-wire connectors with terminal linking control allows all standard connection methods and provide an easy reliable connection.

The geometry of the reflex ports has been tuned to minimise turbulence at high levels, reducing port noise and low-frequency compression.
