Q650c Center Channel Home Theater Speaker

A centre channel needs to perfectly match the home theatre system, Uni-Q technology means the sound is as seamless as the picture.

"Sit anywhere" Uni-Q sound

The Uni-Q driver array places the tweeter in the centre of the midrange and bass cone, bringing the acoustic ideal of a single point source closer than ever. The result, enhanced by KEF's 'tangerine' waveguide over the tweeter, is a more accurate three-dimensional sound that's dispersed evenly throughout the room.

Tweaking the tweeter

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.

A word about drums and bass

The Q Series reproduces the nuances of bass instruments with ease. With a larger roll surround and new suspension KEF drivers produce cleaner bass at high volumes.

A new cone structure improves midrange clarity and an enhanced Auxiliary Bass Radiator (ABR) with a new surround and rear suspension enhances bass quality.

New system design

Putting the Uni-Q driver in its own sealed cabinet reduces the load on the cone and increases clarity and detail while delivering cleaner bass. Midrange clarity is enhanced by driver improvements that mean the DC blocking capacitor to be eliminated from the crossover, allowing a more natural roll-off between drivers.

I set out to buy a five speaker set of main speakers with "matched drivers". I decided on the Q650C, Q750 mains and Q50A Atmos toppers. After owning them for a couple of months I really like how they sound with my Marantz gear. The Q650C could be the highlight of the package. It is clear, open and dynamic. I think it is very obvious to hear that the Q650C and Q750's have identical or extremely similar drivers. The sound blends to form a huge soundstage with very precise imaging.

I know it is possible to spend far more on speakers but I could not be happier with the results.

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.”

Q650c 5.1 Speaker Review

"These speakers have little trouble blistering through the trigger-happy car chase of the opening scenes - they use every ounce of their muscle to pin us back into the sofa.”
