For a speaker like the CI100QR in-ceiling 4-inch two-way Uni-Q with integrated back box, KEF believes that the quality of a speaker is no less important just because it"s out of sight - in fact with ceiling-mounted units it can be more so. Designed to smoothly integrate and architecturally match with existing down lighting sharing the same size bezel KEF"s trademark Uni-Q technology has a decisive performance advantage in these applications because each point source driver array evenly disperses the sound ensuring a smooth frequency response over a large area to create a spacious three-dimensional soundscape with genuine texture and depth. With a two-way 100-millimeter Uni-Q driver, the Ci100QR is as satisfyingly musical to hear as it is neat in appearance. As a latest addition to the KEF Uni-Q custom installation series, the Ci100QR is built for flush mounting into walls and ceilings. Providing a compact solution to the problem of hi-fi quality sound from an in-wall/ceiling speaker the Ci100QR consists of a polypropylene cone LF driver with the HF unit mounted at the acoustic centre of the LF unit. The bezel and grill can be painted to match the interior decor.
