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 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.
