The KEF Q350 Speakers feature an innovative Uni-Q driver array, placing the tweeter in the acoustic centre of the midrange and bass cone in order to result in a more detailed and accurate 3D sound image. This Uni-Q driver has been repositioned to the centre of the cabinet for a reduction in internal resonance and optimisation of sonic clarity and detail.

The KEF Q350 Speakers features a Uni-Q driver array, an innovative array that 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. This driver array will result in a better, more detailed and accurate three-dimensional sound image. This sound will be dispersed more evenly throughout the room than would otherwise be possible in a more conventional speaker. The ultra-wide dispersion of sound through the Uni-Q driver array will be further enhanced through KEF's "tangerine" waveguide over the tweeter dome.

For optimisation of high resolution purity, the Q150's Uni-Q driver has been repositioned into the centre of the cabinet, thus reducing any unwanted internal resonance and adding refinement to the sonic clarity and detail produced. The additional damped tweeter loading tube in the Q350 helps to provide a gentle termination of sound produced from the back of the tweeter. Lower treble performance is drastically improved and a new low-distortion inductor on the crossover will provide a much cleaner bass.

With a Computational Fluid Dynamics port design, in which the port has been relocated to the rear of the speaker unit, the clarity of the Q350 has been significantly improved through reduction of the audibility of the midrange leakage through the port.

The KEF Q350 Bookshelf Speakers are supplied without the grilles, but are available with black grilles as an optional extra.
