KEF’s First Architectural Speaker with MAT™

Featuring innovative technologies including 12th Generation Uni-Q® driver array with Metamaterial Absorption Technology (MAT), patent-pending Cavity Radiation Control and Low Diffraction LF Aperture, Ci250RRM-THX is a truly revolutionary coaxial three-way architectural speaker that delivers immersive, high-fidelity soundstage with unmatched sonic excellence for large home theatres and living rooms.

Low Diffraction LF Aperture

Ci250RRM-THX features Low Diffraction LF Aperture, a carefully profiled, smoothed housing design with an outer acoustically absorptive foam ring that reduces resonance and diffraction. As a result, it delivers exceptional MF/HF performance while preserving a tremendous bass output.

Cavity Radiation Control (CRC)

The latest patent-pending technology developed by the KEF Engineering team in the UK; Cavity Radiation Control (CRC) is a unique open-back midrange with acoustically absorptive foam design that eliminates midrange issues including frequency response dips of up to 30dB in magnitude, found in typical coaxially arranged three-way designs. With CRC, Ci250RRM-THX delivers the highest midrange acoustic realism among three-way coaxial loudspeakers to date.
