Features

"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.

New system design

CFD-designed port

Featuring 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.
