KEF Ci4100QL-THX In-Wall LCR Architectural Single Speaker

The KEF Ci4100QL-THX In-Wall Speaker (sold individually) is a THX Select2 certified LCR solution engineered for professional-grade home theater performance. Designed with KEF’s signature Uni-Q driver array, the tweeter is positioned at the acoustic center of the mid/bass driver to act as a single point source. This ensures even sound dispersion, so every listener hears the same balanced audio no matter where they sit.

Built around a 4" Uni-Q array with three identical mid-frequency drivers, the Ci4100QL-THX delivers studio-accurate sound for both dynamic action scenes and natural dialogue. Whether installed as a front channel, rear speaker, or horizontal center channel, it adapts easily to your room layout.

With its Ultra-Thin Bezel (UTB) design, the Ci4100QL-THX blends seamlessly into walls while maintaining premium performance. KEF’s patented in-wall bracket system ensures fast, secure installation without damage.

THX certification guarantees that this speaker reproduces the tonal balance intended by filmmakers, offering an authentic cinematic experience at home.

Important: Price is for one speaker. For surround systems, multiple units are required.
