The KEF Q900 speakers (available on 0% finance) are the flagship floorstanders in the R series range. They proudly feature 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.
This model really is a statement, for those looking absolute definition from you music or movies look no further than the R900
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.
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 sturdy 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,
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 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.
The all-new R Series represents a decisive step forward in the enjoyment of music or film. By incorporating the high end technologies of previous KEF masterpieces 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, look no further than new R series!
2 Feb 2016Rather large speakers that fill the room with sound. Easy to assemble out the box.
Being able to adjust the carpet spikes from the top is a nice touch.
The high gloss finish on the rose wood is as deep and rich as the sound they produce.
Boxy shape of classic speak style. Magnetic dust covers is a good idea, as it can be easily removed to show of the speakers them selves.
Connections at the back, bi-wired, bi-amp or normal can be set by the little knobs.
I am no expert but to my ears these kef's sound great in my house.
