The Q150 proves that the best things come in small packs. A Uni-Q driver and CFD port mean it performs well above its weight. Q series shelf speakers great in small spaces. KEF Uni-Q driver module plus Computational Fluid Dynamics (CFD) port technology equals high resolution and powerful sound. The Uni-Q driver module places the tweeter in the middle range and bass cone, bringing the ideal acoustics from a single point source closer than ever before. The result, enhanced by KEF's "tangerine" waveguide on the tweeter, is a more precise three-dimensional sound that is evenly distributed throughout the room. With the addition of the cushioning tweeter charging tube providing an end of the sound produced from the back of the tweeter, the low treble performance is significantly improved and a new low-distortion inductor on the crossover provides cleaner bass. Available in satin black, white and walnut. Magnetic speaker grids can be purchased separately.
