KEF R900 Floorstanding speakers

KEF's R series features many of the prestigious speaker company's latest and most impressive innovation in premium high fidelity audio and home theatre loudspeaker technology. The R series takes authentic audiophile quality standards and brings them to a much more affordable price range. The range utilises KEF's latest Uni-Q driver array, combined with newly developed bass drivers and enhanced components throughout. This results in a wide and vast stereo image, complete with flawless accuracy that many reference level speakers from lesser brands are unable to achieve

The R900 loudspeakers from presitigious speaker manufacturer 'KEF' makes use of impressive twin 8-inch LF drivers, which have been precisely and specifically positioned either side of critically acclaimed Uni-Q driver, a signature driver array utilised by KEF. The R900 promises an unbeatable sound-field, complete with a dynamic depth that competitors in a similar price range, and even more expensive competitors struggle to achieve. 

The upper registers are connected together with a great attention to detail and flawless precision, while the bass drivers of the speakers retain a highly authoritative control over the low frequencies. This provides a smooth and undistorted response, forming a truly immersive listening experience with a level of realism and accuracy that will impress even the most attuned audiophiles.
