2-way bookshelf
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.
Q Series takes cutting-edge acoustic technology from ranges including The Reference and Blade to a wider selection of people. Representing exceptional value, Q Series unlocks detail and depth in whatever you choose to listen to.
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.

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.
Full-length magnetic grilles are optional.
