Hi there! How can we be of assistance?

Powerful, high-fidelity sound

As part of the Extreme Home Theatre line-up within KEF Architectural Speakers, Ci250RRM-THX is engineered to deliver powerful, room-filling, high-fidelity sound for the most discerning music and movie lovers.

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.

Designed to perform

Engineered to be structurally robust with a premium aesthetic, the bespoke Ultra-Thin Bezel (UTB) offers the slimmest visible rim around the speaker while casting virtually no shadow. The paintable UTB and magnetic grille ensures the speaker seamlessly blends into the environment.

Ci250RRM-THX is splash water and dust proof with IP64 certification. With a well-considered mechanical design, Ci250RRM-THX ensures ease of installation with minimum of fuss.

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.

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.

Uni-Q®Sit anywhere, hear every detail

Uni-Q technology is the building block of KEF signature sound. Designed to perform at its best in Ci250RRM-THX, the remarkable 12th generation Uni-Q driver array acts as a single point source, dispersing sound more evenly allowing everyone sitting at different spots in the room to experience the same natural detailed sound.

MAT™Absorb 99% of the unwanted sound

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.
