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.
