KEF Q650c Center Channel Speaker (Each, White)
From the manufacturer
The Q650C centre channel speaker features the KEF signature Uni-Q driver array, and without a rear port it can be placed inside a cabinet with ease, creating precise, captivating dialogue.
"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 levelWith 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. To optimize the resolution and purity of the Q Series bookshelf speakers, the Uni-Q driver has been repositioned to the center of the cabinet to reduce unwanted internal resonance and adds refinement to their sonic clarity and detail. |
CFD Designed PortLow-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. |
Q Series OptimisedThe Q650c features an optimised cabinet to reduce unwanted vibrations and resonances and removal of the rear port. The Q650c is not just designed as a center channel speaker but is an excellent option for a discrete Left Center Right combination where space is at a premium. |
