In detail
About the Ci100QS
Overview
The KEF Ci100QS is a square custom install speaker from KEF's Q Series (Soundlight) architectural range, built to sit flush in a dry-lined or stud partition wall or ceiling. It uses a 100mm (4 in.) Uni-Q driver array with the tweeter mounted at the acoustic centre of the bass/midrange cone, so both drivers radiate from a single point. KEF rates its nominal coverage at 150°.
An Ultra-Thin Bezel (UTB) keeps the visible rim narrow, and the grille attaches magnetically. Both the grille and bezel can be painted to match the surrounding surface. KEF lists the Ci100QS as weather resistant and IP64 certified, with a UV-protected bezel and grille.
Grille and Finish
- Grille attaches magnetically
- Ultra-Thin Bezel (UTB), no more than 5mm wide according to KEF
- Grille and bezel are white and can be painted; a paint shield is included for the grille
- Weather resistant construction with UV-protected bezel and grille, IP64 certified
Cinema design
Part of something bigger.
The Ci100QS is one piece of a room. We design the screen, speakers, acoustics and seating around it, then install and calibrate the lot, so it all works as one.
