The KEF Ci160CS In-Ceiling Speaker is a high-performance architectural audio solution designed to deliver detailed, room-filling sound while blending seamlessly into modern interiors. Featuring KEF’s signature 6.5” Uni-Q driver array, this in-ceiling speaker places the tweeter at the acoustic center of the mid/bass cone, creating a wide, even sound dispersion that ensures consistent audio coverage throughout the room.
With an 8-ohm nominal impedance and 89dB sensitivity, the Ci160CS integrates easily with a wide range of amplifiers, making it suitable for both residential and light commercial installations. Its 2-way design provides clear, articulate highs and smooth midrange performance, while the 160mm (6.5-inch) driver delivers controlled, balanced low-frequency response. The result is natural, immersive sound ideal for background music, home theater surrounds, or multi-room audio systems.
Designed for discreet installation, the Ci160CS features a slim bezel and paintable grille that allows it to blend effortlessly into ceilings without disrupting the room’s aesthetics. The open-backed design offers installation flexibility, and optional accessories such as a rear enclosure and rough-in frame make it adaptable to various construction requirements.
Whether used in living rooms, kitchens, offices, retail spaces, or hospitality environments, the KEF Ci160CS provides reliable performance, wide sound coverage, and the refined acoustic engineering that defines KEF’s architectural speaker range.
