Featuring many of KEF’s latest innovations in premium hi-fi and home theatre 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
R300 is the larger bookshelf model offered in the KEF R Series line of high performance home audio speakers. It features KEF's patented 5in.Uni-Q driver array and a 6.5in. LF bass to deliver fast and clean mid-range response, along with accurate and clean low-end frequencies. This specially designed Uni-Q driver is nothing short of 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, 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.

Advanced Bass Technologies
The R Series 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., fast and clean midrange response. And as the speaker footprint is the same, no more space is required.

Inside the cabinets (in a choice of classic Piano Black, Piano White 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.

    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

    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 - audio-head
    "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."
