KEF Ci160.2CS Square In-Wall/In-Ceiling Custom Speaker

The KEF Ci160.2CS is a high-quality in-wall and in-ceiling loudspeaker designed for custom audio installations in homes, commercial spaces, and multi-room environments. It’s part of KEF’s Ci-C Series, which focuses on delivering immersive sound while remaining visually discreet. The speaker uses KEF’s patented Uni-Q® driver array, in which the tweeter is positioned at the acoustic center of the bass/midrange driver. This design helps the driver operate as a single point source, producing smooth, evenly dispersed sound across a room rather than directing audio narrowly, so listeners get a more uniform listening experience regardless of their position.

This model features a 160 mm (6.5″) Uni-Q driver paired with a 16 mm (0.6″) aluminum dome tweeter with a waveguide that enhances high-frequency dispersion. The result is clear, detailed sound with solid midrange presence and crisp treble, making it suitable for music, movies, and general playback. The speaker has a nominal impedance of 8 Ω and a sensitivity around 89 dB, and it works well with a wide range of amplifiers rated roughly 10 W to 100 W, which gives flexibility in system design without requiring high-power amplification.

Aesthetically, the Ci160.2CS is designed to blend into its surroundings. It has an ultra-thin bezel that keeps the visible edge of the speaker minimal after installation. The supplied grille is paintable, allowing it to match the wall or ceiling finish seamlessly. For installations where exposure to moisture or humidity is a concern, the speaker is weather-resistant with an IP64 certification, making it suitable for use in bathrooms, kitchens, or semi-covered outdoor areas.

Installation is straightforward thanks to its relatively shallow mounting depth, so it can fit into many ceilings or walls where other larger speakers might not. Optional accessories such as rough-in frames and rear enclosures help simplify construction-phase fitting and improve acoustic performance when installed in stud walls or other cavity types.
