| Content | “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.
