KEF Ci160RR-THX 6.5" In-Ceiling / In-Wall Speaker
KEF Ci160RR-THX 6.5" In-Ceiling / In-Wall Speaker
If the ceiling has a bedroom or other living space above it, or is part of an escape route, building regulations require each speaker to have a fire hood. Hoods also cut sound leaking into the room above.
Allow about 10m per speaker for a typical run back to the amplifier. Webro 16/2 LSZH (low smoke, zero halogen) is the right cable for runs in ceilings and walls.
The KEF Ci160RR-THX is a premium 6.5" in-ceiling and in-wall speaker designed for discerning listeners who want serious sound quality without visible hardware. THX Ultra certified, it's equally at home delivering stereo music in a kitchen or living room as it is powering surround and height channels in a dedicated home cinema.
Why we like it
- KEF's acclaimed Uni-Q driver array places the tweeter at the acoustic centre of the mid/bass cone for even, coherent dispersion throughout the room
- THX Ultra certification guarantees cinema-accurate performance for home theatre installations
- Extended frequency response delivers genuine depth and detail across the full audio spectrum
- Paintable ultra-low profile grille and slim bezel disappear into any ceiling or wall finish
- Shares a universal 160mm-class cut-out with other KEF Ci-series models, simplifying upgrades or replacements
Installation notes
This speaker requires a 196mm cut-out diameter and a mounting depth of 115mm, with an external face diameter of 234.6mm once installed. Given its 4 ohm impedance and wide 10-190W power handling, it pairs well with multi-room amplifiers such as a Sonos Amp, or a WiiM Amp for streaming-based setups. Always check ceiling void depth before installation to ensure a proper fit.
