KEF : Q-150a Atmos (Black)
Dolby Atmos flexible surround

Dolby Atmos offers the potential for full immersion cinema, the Q50a uses Uni-Q technology to deliver it in full effect.

Optimised for Q Series home theatre systems the Q50a Dolby Atmos-Enabled Surround Speaker features the latest Uni-Q driver array and advanced technology for serious dynamics and accurate, clean sound.

TECHNOLOGY

"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.

Q50a brings immersive Dolby Atmos height to Q Series home theatre systems. It is also easily mounted on the wall for a high-fidelity surround sound experience. Its Damped Tweeter Loading Tube produces a detailed and natural high frequency sound, and the styling means the Q50a will blend seamlessly into any interior.

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.
