Description
True Cinema Sound, Built Into Your Walls
THX Certified performance without compromising your living space
The KEF Ci3120QLM-THX is a premium in-wall loudspeaker designed to deliver authentic cinematic performance while blending seamlessly into modern interiors. THX Certified Select and engineered for medium-sized rooms, it combines exceptional clarity, powerful dynamics and immersive surround sound without occupying valuable floor space.
Advanced KEF Acoustic Technology
Uni-Q® and MAT™ working together
At the heart of the Ci3120QLM-THX is KEF’s 12th generation Uni-Q® driver array, enhanced by Metamaterial Absorption Technology (MAT™). Acting as a single acoustic source, Uni-Q disperses sound evenly throughout the room, while MAT™ absorbs unwanted rear-wave energy to reveal greater clarity, precision and natural detail.
Powerful Bass. Exceptional Control.
Engineered for cinematic impact
Two custom 120mm bass drivers deliver deep, controlled low frequencies with impressive dynamics and minimal distortion. Whether reproducing explosive movie soundtracks or delicate musical passages, the Ci3120QLM-THX maintains excellent balance, accuracy and authority.
Optimised for Home Cinema
Three-way design for uncompromised performance
A carefully engineered three-way crossover allows every driver to perform within its ideal operating range. The result is smoother integration, greater vocal clarity and a more realistic, immersive soundstage across every seat in the room.
Designed to Disappear
Premium performance with discreet aesthetics
A paintable magnetic grille and Ultra-Thin Bezel allow the speaker to blend naturally into virtually any interior. Once installed, the focus remains entirely on the sound rather than the loudspeaker itself.
