The KEF Ci160CSds

The KEF Ci160CSds is an innovative square-format in-ceiling (or in-wall) speaker that recreates stereo audio from a single flush-mounted unit—ideal for spaces where installing two speakers isn’t practical. It delivers full-range sound using a dual 160 mm Uni‑Q driver with two 19 mm tweeters, ensuring rich, immersive stereo with precise imaging and wide dispersion. Designed with weather-resistant fixings and a low-profile magnetic grille with ultra-thin bezel, it integrates seamlessly into any décor and is built to withstand moisture, making it suitable for bathrooms, covered outdoor areas, or premium residential installations.
