OVERVIEW For music or movies, your installation needs to deliver the flawlessly accurate three-dimensional sound you’d expect from the best conventional speakers – startlingly clear and breathtakingly realistic. And that’s exactly what our Ci range does. KEF’s passion for acoustic excellence shines through in every model. By combining radically innovative engineering with sophisticated design technologies, the Ci range achieves what used to be thought impossible: compact custom installation speakers that sound as compelling as an audiophile quality hi-fi system, no matter where you sit. With impeccable cosmetics, there’s a KEF Ci model for every application, from tiny ceiling speakers the size of downlights to motorised super-premium home theatre speakers that glide into place at the touch of a button. All are ruggedised for harsh environments such as bathrooms or boats. All KEF speakers are sonically-matched, so any combination you specify for different listening areas will have the same tonal colour for a perfectly consistent soundstage. Fast, easy installation has always been valued by Ci Series installers. With only a few simple steps and KEF’s unique design features, Ci speakers can be fitted quickly, with no special skills. Once the hole is cut and the cable run, the area is soon flooded with great high definition sound. TECHNOLOGY The popular Soundlight Series is yet another major innovation form KEF. When installed, Soundlight speakers are so tiny that they blend in with halogen light fixtures yet will amaze you with their astonishing performance. Features and Benefits Purpose-built for flush mounting into walls and ceilings, the Ci50R delivers KEF audio quality as unobtrusively as possible, and with KEF’s standard lighting style fitting, you’ll also find them amazingly easy and rapid to install. Applications The Ci Series Ci50R is best suited for plastered or suspended ceilings where high quality background music and speech reinforcement applications require hi-fi performance such as: • Multi Room systems • Lounges, Bars, Boutiques • Boardrooms & Offices Architectural Specifications The Ci Series Ci50R comprises a 50mm full range speaker.
