Product Description

KEF R900 Floor Standing Speakers

Featuring many of KEF’s latest innovations in premium hi-fi and home theatre loudspeaker technology, the all-new R Series makes genuine audiophile standards of entertainment more affordable than ever before.

Stunningly fluent new Uni-Q driver arrays combine with potent new bass drivers and many ingenious refinements to create a rich, spacious sound image of such accuracy that it approaches the benchmark standards of KEF’s legendary Reference Series.

KEF R Series Informational Video:

The new Uni-Q MF/HF driver array is a masterpiece.

Midrange response is amazingly fast and clean, thanks to a braced magnesium/aluminium alloy cone, with KEF’s Z-flex surround smoothing the transition to the front panel and a sturdyTHE ALL-NEW R SERIES die-cast aluminium chassis that prevents resonance being transferred to the cabinet.

At the acoustic centre of the midrange cone is the sophisticated vented tweeter that endows KEF Blade with such startlingly pure HF response. With a large neodymium magnet and a computer-optimised dome structure so stiff that it operates pistonically over its entire working range, the upper registers are articulated with flawless precision – and to capitalise on Uni-Q’s point source characteristics, KEF’s ‘tangerine’ waveguide helps to disperse the higher frequencies evenly across a wider angle to flood the room with an intricate and refreshingly natural soundfield. Operating together as a single, perfectly integrated voice, the array as a whole delivers a sweet, accurate sound of unprecedented clarity.

The new bass driver is equally impressive.

The combination of a massive vented magnet assembly and a large, lightweight aluminium voice coil driving a light, stiff and strong hybrid cone assures clean, deep and uncompressed bass output with superb dynamics and power handling.

Inside the cabinets (in a choice of classic Piano Black and real wood veneer finishes in Rosewood or Walnut) every single component confirms KEF’s technology leadership.

Computer-designed crossovers allow the level of each driver to be fine-tuned for a smoother, flatter response.

Constrained layer damping panels prevent cabinet vibration from muddying the mid-range and bass – even the airflow through the reflex ports is managed using computational fluid dynamics to optimise acoustic integrity.

With nine timelessly handsome models including three assertive floorstanders, two bookshelf speakers, two fully-specified centre channels, dipole surrounds and a matching subwoofer, the all-new R Series represents a decisive step forward in the enjoyment of music or film.

By incorporating the high end technologies of KEF Blade in a classically elegant format, it gives serious audiophiles phenomenally accurate reproduction that neither adds to nor subtracts from the original recording: refined, spacious and exquisitely detailed.

For those whose appreciation of true audio excellence outstrips their bank balance, it’s the perfect buy.

With twin 8-inch LF drivers positioned perfectly either side of the remarkably sweet and accurate latest generation Uni-Q driver array, the KEF R900 ensures an incredible scale and depth.

Upper registers are articulated with flawless precision, whilst the bass drivers maintain authoritative control over the LF – providing undistorted, earth moving realism and accuracy that will awaken your very soul.
