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 mid-range cones are rigid magnesium/aluminum constructions that reduce breakup problems. The 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.
KEF R SERIES UNI-Q DRIVER R300
KEF R SERIES WOOFER R300 Power

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.
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 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.
KEF R SERIES CABINET
KEF R SERIES TERMINALS R300 Simplicity

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.

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.

The speakers sound great, but very poor choice of finish (black,"white?" or Walnut).
I also have a pair in rose wood that look much better than the choices available now. (Posted on 2017-03-24)

After lots of reviews I decided on the R300's as a major speaker upgrade in a fairly large room. They did not disappoint me in any aspect. Beautiful sound that will be music to your ears! A beautiful build all around. The sound clarity is exceptional and more than enough bass for my taste. Can't wait to review my entire music collection! (Posted on 2016-12-24)
Fantastic Balance between highs and lows, with exceptional clarity and smooth response Review by Robby

Would you recommend?
These speakers assume a prominent location in my "man cave." As an owner of the T305 and X300AW systems, I was familiar with KEF's commitment to high quality design and uncompromising sound. My dilemma was whether to purchase the LS50 or KEF R300. I made the right choice. With the additional bass drivers and accompanying fuller sound, these speakers were all I needed to satisfy my ears and complete my system. Thank you, KEF for your continuing legacy of excellence. I am a customer for life! (Posted on 2015-10-02)

KEF R300 Bookshelf Loudspeakers from KEF, KEFDirect Review - c|net
"There's an undeniable ease to the sound, the R300 doesn't shout "detail" or "resolution," but the clarity is there. It's just easier on the ear, it's closer to the way live, unamplified music sounds in real life."

"The fit and finish are classy, upscale and defiantly offer more than many others, which can’t be overlooked. These 3 way delights are the step up from the LS50s. Razor sharp sound, serious focus and a swift, dynamic response all make these stand mount loudspeakers a must-audition for anyone in the game for a bookshelf-style music maker."
