Complete your setup
Everything this camera needs, matched by our specialists. Silarius picks first.
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.
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.
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.
KEF Q Series Q150 Bookshelf Speaker
KEF Q Series brings cutting-edge acoustic technology from ranges such as the legendary KEF REFERENCE and Blade loudspeakers to a wider audience. Representing exceptional value, the Q Series continues to win awards globally by unlocking detail and depth in whatever you choose to listen to.
The remarkable Q Series bookshelf speakers excel when space is limited. Featuring the signature KEF Uni-Q driver array with Computational Fluid Dynamics (CFD) port design, the Q150s deliver detailed natural sound with high clarity and tight bass.


“Sit anywhere" Uni-Q Sound
At the heart of Q150 is the Uni-Q driver array. KEF's signature innovation places the tweeter in the acoustic center of the midrange cone, bringing the acoustic ideal of a single point source closer than ever to realization. The result is a more detailed, more accurate three-dimensional sound image, which is dispersed more evenly throughout the room than is possible with a conventional speaker. Uni-Q's ultra-wide dispersion is further enhanced by KEF's Tangerine' Waveguide over the tweeter dome.

Uni-Q to the Next Level
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 response.
