The larger of the two bookshelf speakers available in the Q Series. The remarkable Q350 speakers excel when space is limited and greater bass is needed. Featuring our signature KEF Uni-Q driver array with Computational Fluid Dynamics (CFD) port design, the Q350s deliver detailed natural sound with high clarity and tight bass. The Q350 have the ability to fill even larger rooms with robust and detailed sound. At the heart of the evolved Q Series is the Uni-Q driver array. KEFs 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-Qs ultra-wide dispersion is further enhanced by KEFs tangerine waveguide over the tweeter dome.
