"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.

KEF Q Series Uni-Q Driver Updates Q650c Center Channel SpeakerUni-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.

KEF Q650 Center Speaker Review Hi-Def Digest Q650 Loudspeaker Review - Hi-Def Digest
 "...the two 6.5" drivers and one 6.5" ABR deliver clear vocals and distinct imaging across the front soundstage. In swapping between the Q650c, old iQ6c, and a $200 center channel from another brand, returning to the Q650c is a delight thanks to its accuracy. You can even set them to "large" in your AVR's speaker settings with a 60Hz crossover and come away with no distortion. That's impressive. In an age where most people (understandably) go for a simple sound bar system, three cheers for a nice, beefy center channel that can keep up with its badass tower brothers.”
