KEF Ci250RRM-THX In Ceiling Speaker - Each
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.
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.
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.
The Ci250RRM-THX is the first architectural speaker that benefits from our acoustic innovation: Metamaterial Absorption Technology (MAT™). MAT is a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the tweeter, delivering a more crisp, natural treble performance.
Featuring a 250mm (10 in.) LF driver, Ci250RRM-THX delivers deep, room-filling bass down to 28Hz. Together with the 100mm (4 in.) Uni-Q driver array with MAT, Ci250RRM-THX delivers powerful, high-fidelity sound with maximum SPL of 111dB.
