The KEF Q150 proves that the best things come in small packages. A Uni-Q driver and CFD port mean it punches way above its weight.

Q Series bookshelf speakers excel in small spaces. KEF’s Uni-Q driver array plus Computational Fluid Dynamics (CFD) port tech equals high resolution and big sound.

“Sit anywhere” Uni-Q sound

The Uni-Q driver array places the tweeter in the center of the midrange and bass cone. This results in bringing the acoustic ideal of a single point source closer than ever. Consequently, the result enhanced by KEF’s ‘tangerine’ waveguide over the tweeter, is a more accurate three-dimensional sound. Therefore dispersion is even 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.  Moreover, a new low-distortion inductor on the crossover provides the KEF Q150 with 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.   Additionally, 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.

All this allows the KEF Q150 to provide superior performance from a small package.  Pricing is for a pair.
