“Sit anywhere" Uni-Q Sound
At the heart of the evolved Q Series is the Uni-Q driver array. KEF\'s signature innovation places the tweeter in the acoustic center of the midrange cone, bringing the acoustic ideal of a single point source closer than ever to realisation. The result is a more detailed, more accurate three-dimensional sound image, which is dispersed more evenly throughout the room than is possible with a conventional speaker. Uni-Q\'s ultra-wide dispersion is further enhanced by KEF\'s \'tangerine\' waveguide over the tweeter dome.
Uni-Q sound taken to the next level
The closed box midrange cabinet design reduces the load on the Uni-Q midrange cone, increasing clarity and detail while delivering cleaner, punchier bass.
With the addition of the Damped tweeter loading tube providing a gentle termination of sound produced from the back of the tweeter, lower treble performance is improved dramatically and a new low-distortion inductor on the crossover provides cleaner bass response.
Redesigned Bass Drivers
Low-frequency (LF) drivers now have a larger roll surround, along with a new spider suspension to produce cleaner bass at high volumes. A new cone structure improves midrange clarity, and an enhanced Auxiliary Bass Radiators (ABRs) with a new surround and rear suspension delivers better controlled and more impressive bass.

The CM8 is an elegantly proportioned, slimmed down version of the award-winning CM9. A true three-way loudspeaker that will appeal to discerning customers who demand the very best sound quality, but have limited space in which to achieve it.
Like all the models in the CM Series, the CM8 uses crossovers of remarkable simplicity and quality, so what you hear is that much closer to the sound of the original recording. In its functional perfection and understated elegance, itʼs nothing less than a masterpiece. Pure and simple.
All CM Series speakers come with chrome driver trims. Grilles attach magnetically, so there are no unsightly grille-mounting features to spoil the clean lines of the speakerʼs façade. For the finish, you can choose either one of two real-wood veneers in Rosenut or Wengé, the highly polished gloss black or the new stylish white.

If itʼs hard to put the sound of the CM9 into words, thatʼs just as well. This top-of-the-range floorstanding speaker will fill even the largest domestic spaces with music so richly detailed, and so startlingly lifelike, that it will leave you speechless.
The three-way CM9 delivers truly commanding bass with the aid of twin 165mm paper/Kevlar® cone drive units. An FST® driver, with its characteristic compression surround supporting the outer edge of the distinctive Kevlar® cone, is specially developed for outstanding midrange performance. The CM9ʼs Nautilus™ tube-loaded aluminium dome tweeter keeps high frequencies crisp and sharp all the way up to 50kHz and beyond.
The quality of CM Series drive units has made it possible to use minimalist crossovers throughout the whole range. The resulting gentle transition between drivers avoids the unnaturally rapid changes in dispersion that bedevil more complex designs, while the high quality components, carefully chosen after exhaustive listening tests, ensure that as little as possible gets between you and the sound of the original recording.
All CM Series speakers come with aluminium driver trims. Grilles attach magnetically, so there are no unsightly grille-mounting features to spoil the clean lines of the speakerʼs façade. For the finish, you can choose either one of two real-wood veneers in Rosenut or Wengé, or a highly polished gloss black.
