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.
