DESCRIPTION

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.

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's signature sound. Designed to perform at its best in Ci250RRM-THX, the remarkable 12 th 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.

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, the Ci250RRM-THX delivers deep, room-filling bass down to 28Hz. Together with the 100mm (4 in.) Uni-Q driver array with MAT, the Ci250RRM-THX delivers powerful, high-fidelity sound with a maximum SPL of 111dB.

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 dialogue-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 ensure that the speaker seamlessly blends into the environment.

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

    Very professional work and an excellent result. They installed a sound system in a Mercedes Viano camper, and the acoustics and sound detail are now on a completely different level! It's almost on par with what I hear at home from quality speakers. The subwoofer is perfectly chosen, just right for my taste. Everything was done extremely carefully, with no extraneous noises or plastic rattling, and the wiring and integration are flawless. True professionals in their field, I recommend them.

    I upgraded the original audio system in my Alfa Romeo SUV. We started with sound insulation and front door speakers with an amplifier. We finished with an additional amplifier with DSP and professional tuning :) The result exceeded all expectations. I've been using it for a year now and don't want to get out of the car :) The work was done super PRO. When questions or options came up along the way, they discussed them with me, consulted and advised. The best investment and modification I've ever made to a car, and I don't regret a single euro. Highly recommend

    Excellent service! The "Autogarso" team quickly and professionally installed a dash cam in my car. I especially want to thank administrator Robertas for his pleasant communication, thorough consultation and attentive approach to the customer. I recommend it to everyone looking for reliable car electronics specialists.

    I had sound and vibration insulation installed in the doors, wheel arches, trunk, and under the rear seat. The result was really noticeable. BMW g31
