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 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 idea 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 centre 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 Computational Fluid Dynamics (CFD) port design with the port repositioned to the rear of the speaker, clarity is improved by reducing the audibility of the midrange leakage through the port.
