“Sit anywhere” Uni-Q sound from the KEF Q50a

At the center of the Q series is the Uni-Q driver. The patented “Sit-Anywhere” Uni-Q driver arrangement places the tweeter in the acoustic center of the bass/midrange cone, realizing the acoustic ideal of a single-point sound source better than ever before.

The result is a more precise sound image that is distributed more evenly throughout the room than is possible with conventional speakers.

Optimized tweeter

The integration of the damped tweeter with tube technology eliminates noise from the back of the tweeter, as well as dramatically improves the lower high-frequency response. A new low-distortion inductor on the crossover provides clearer bass response.

Drum and bass reproduction

The Q Series faithfully reproduces the subtleties of powerful bass instruments. The woofer drivers now have a larger rubber surround, which together with a new basket suspension provide clearer bass response at high volumes. A new cone structure improves midrange brilliance and an optimized passive woofer (ABR) with a new all-around and rear suspension provides better controlled and more impressive bass.

New Q Series system design from KEF

Placing the Uni-Q driver in its own sealed cabinet reduces stress on the diaphragm, increasing clarity and detail while producing clean bass.

Midrange clarity is enhanced by driver improvements. Also, the DC block capacitor has been removed from the crossover, allowing for a more natural roll-off between drivers.
