Pushing Technological Boundaries

KEF always pushes the technological boundaries in its mission to create the best possible sound; Ci250RRM-THX is the physical manifestation of that drive.

Absorb 99% Of 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.

Powerful, High-Fidelity Sound

As part of the Extreme Home Theater 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.

THX Certified

Ci250RRM-THX delivers ultra-high performance with true theater sound quality for large theaters and living rooms and it is certified to THX® Ultra. A deep understanding of the filmmaking process and surround sound is at the very heart of every THX® certified speaker system. Engineered with design characteristics of professional studio speakers, THX® recreates the tonal balance of the filmmaker's final mix in your home theater or living room. The results? Action sequences are impactful, and dialog-driven moments are natural and engaging.

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.
