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.


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.

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 veneer, or highly polished Piano Black or White, the R Series complements the home as much as it respects the music.

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.

I purchased a pair of the R900's (Piano Black) back in August, of '17. I'm running a Parasound P-5 preamp, thru (2) Parasound A-23 power amps, as mono blocks. I have them "toed in", slightly. The sound is clear, and clean. They handle the 400 watt mono blocks with no problem!! I rarely turn the volume up past the "10 o'clock" position, as they're plenty loud at that point. I'm pleasantly surprised at how great they sound, from a long throw aspect. They sound so sweet, even when you're listening off axis. I think that they're awesome speakers, and wish that I had purchased them sooner..... (Posted on 5/1/2018)

After months of researching speakers, travelling up to 200 miles to listen to various brands.
I had settled for a different brand that cost literally 2.5 times the price of the 900's
Right before I finalized the purchase, the dealer of Kef in South Florida, who I have known for over a decade, and I had a chat about kef.
so taking his word, I ordered them without auditioning them first.
Well that was the best decision I have ever made.
These speakers are beyond incredible, the SOUND!!!! WOW !!!
clarity, bass, imaging, depth and all the other words audiophiles use to describe speakers, belong to speakers that cost 3 or 4 times more.
and the best way I have to describe the sound that these jewels produce, is that for the first time in my life I can really feel the music touching my soul!!!!
Thank you KEF for making these. (Posted on 12/29/2017)

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 11/2/2016)

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 5/21/2015)

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)

"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."

HiDef Digest Review
"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.
