The 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 At the heart of the evolved Q Series is the Uni-Q driver array. The signature innovation places the tweeter in the acoustic centre of the midrange and bass cone, bringing the acoustic ideal of a single point source closer than ever to realisation. The result is a more detailed, accurate three-dimensional sound image, which is dispersed more evenly throughout the room than is possible with any conventional speaker. Uni-Q's ultra-wide dispersion is further enhanced through KEF's 'tangerine' waveguide over the tweeter dome.

 

 

 

New system design
To optimise the high-resolution purity of the Q Series bookshelf speakers, the Uni-Q driver is repositioned to the center of the cabinet to reduce unwanted internal resonance and adding refinement to sonic clarity and detail. 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.
