KEF June Specials!  KEF Direct

Featuring many of KEF’s latest innovations in premium hi-fi and home theater loudspeaker technology, the R Series family of home audio speakers make genuine audiophile standards of entertainment more affordable than ever before. Stunningly fluent Uni-Q driver arrays combine with potent custom-designed 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.

R Series Uni-Q Driver
At the acoustic center 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-optimized dome structure so stiff that it operates pistonically over its entire working range, the upper registers are articulated with flawless precision – and to capitalize 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.

R Series Bass Driver
R900 features twin 8-inch LF drivers positioned above and below the remarkably sweet and accurate 5.25" Uni-Q driver array. This specially designed Uni-Q driver is nothing short of a masterpiece. Mid range 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.

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.

Incredible speakers Review by Robert

I have had my R900s for about 2 years now am as happy with them now as when I first purchased them. I liked listening to music prior to buying these speakers but after upgrading to the R900 I tend to spend some time each day listening to music for a bit just to experience the incredible clarity, detail, and well balanced sound. I hear something I missed each time I listen. I also use these as the fronts along with an R600c in a 7.1 system and movie and TV watching is just as enjoyable. The build quality is fantastic and they look great too. (Posted on 11/1/2016)

Basically if you are an audiophile that needs to hear all the details that were originally recorded and want to hear exactly what was laid down on the tracks and meant to be heard. The R900 are the ones. They reproduce sound the way it was supposed to be heard. Outstanding Stereo Digital to Analog Duplication. (Posted on 5/20/2015)

The KEF R900's achieve a balance and refinement I have yet to experience in a speaker in this price range. The speakers create a complex, holographic sound-stage with crystal clear separation and depth. The Uni-Q drivers' ability to accurately re-create vocals is impressive, and there is absolutely no bleed through among the instruments. Build quality is second to none and the R900's passed my spouses aesthetics test with flying colors. If you're looking for a speaker system that is accurate, detailed and musical, look no further.

I have the R900 and I would say
the best way to describe the experience
is to say “it is like sitting inside a set of headphones
only clearer without any constriction” (Posted on 5/24/2012)

Review
"If you're looking for premium speakers to fill your home theatre and handle a variety of musical genres, you can't do much better than the KEF R Series. Transparent. Well-rounded. Superb rendering and imaging at all volume levels. A powerful-yet-compact subwoofer. Fantastic in pieces, but as a complete sysem your home will sound better than your local movie theatre."

"The KEF R900 speaker is a well-conceived, three-way tower that performs well above its price point. As a stereo pair, the speakers offers a balanced symmetry with airy highs, a very good midrange and ample low-end with nary any bloominess."

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.
