The KEF Ci4100QL-THX is a THX Certified Select in-wall speaker built for cinematic surround sound with a discreet architectural finish. As part of the Ci-Q Series, it pairs KEF's patented Uni-Q driver array with an Ultra Thin Bezel (UTB) design, giving you tremendous freedom to position the speaker while keeping the visible rim to a minimum.
KEF's sophisticated sit anywhere Uni-Q array places the tweeter in the acoustic centre of the bass/midrange cone. This lets the tweeter and woofer act as a single point source, dispersing sound widely and evenly throughout the room for consistent imaging and balanced performance.
The result is the best of both worlds: THX surround sound performance from components that blend harmoniously with virtually any room decor. For custom installation, the Ci4100QL-THX combines flexible placement with clearly defined cut-out, wall thickness, and mounting depth requirements to help streamline planning.
