KEF R7 Meta Floorstanding Loudspeaker
The mid-sized floorstanding member of the R Series is as powerful as it is flexible. Its 12th generation Uni-Q® driver array with MAT™ ensures a crystal-clear performance with music and movies alike, while its two 6.5” hybrid aluminium bass drivers deliver accurate, dynamic bass.
Revolutionary sound absorption with MAT™
At the heart of the latest R Series is Metamaterial Absorption Technology (MAT), a revolutionary innovation that takes the performance of the 12th generation Uni-Q driver array to another level in terms of accuracy and clarity.
MAT is a highly complex maze-like structure, where each of the intricate channels efficiently absorbs a specific frequency. When combined, the channels act as an acoustic black hole, absorbing 99% of the unwanted sound that comes from the rear of the tweeter, eliminating the resulting distortion and providing a purer, more natural acoustic performance.
KEF's Uni-Q
KEF's ingenious idea of placing the tweeter in the acoustic centre of the midrange cone brings the acoustic ideal of a single-point source closer to realisation. The new R series benefits from the new 12th generation of the legendary Uni-Q which has been extensively designed using KEF's in-house simulation and analysis tools. KEF's smart engineers have found a way to reduce the colouration by reducing the resonance in the minute gaps between Uni-Q's separate elements, which will result in a much purer sound, more precise and will make stereo imaging far more believable.
Who is KEF and what is their R series?
KEF is a highly renowned, multi-award-winning loudspeaker manufacturer, whose high-quality products can be found all over the world. They were founded in Maidstone, Kent in 1961 by electrical engineer Raymond Cooke, who was awarded an OBE by Queen Elizabeth II in 1979. The KEF name comes from Kent Engineering & Foundry, who were previous occupants of the KEF site. The company have designed loudspeakers for the BBC and has a vast range of products at many different price points.
KEF's R series features many of the prestigious speaker company's latest and most impressive innovations 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.
