If you’re serious about home theatre, the KEF R800ds provides exceptional surround capabilities. The twin 5-inch Uni-Q driver arrays work out of phase to create a remarkable, hard to localise sound field. This results in stunning dynamic sonic effects that help put you at the heart of the action.
Featuring many of KEF’s latest innovations in premium hi-fi and home theatre loudspeaker technology, 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, 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.
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., 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 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.PURE
The R Series presents the high-end technologies of KEF Blade in a timeless, elegant format. Serious audiophiles can now enjoy phenomenally accurate reproduction that neither adds nor subtracts from the original recording. Indulge in a near-Reference experience at a price that will also be music to your ears.
Refined, spacious and exquisitely detailed, you won’t just hear music the way it was intended it to be… you’ll live it, feel it and love it.
