KEF Q550

“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 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.

New Cabinet Design

In our newest line of Q Series Floorstanders the Uni-Q driver has been placed in sealed box within the cabinet. The closed box midrange cabinet design reduces the load on the Uni-Q midrange cone, increasing clarity and detail while delivering cleaner, punchier bass. Midrange clarity is enhanced again through improvements to the mid-bass driver that allowed the DC blocking capacitor to be eliminated. Its removal also created a more natural bass roll-off between the drivers.
