KEF Extends Architectural Speaker Series

KEF has announed the brand has extended their range of architectural speakers with two new THX Certified models; the three-way coaxial speaker Ci250RRM-THX and the architectural subwoofer Ci250RRb-THX.

Ci250RRM-THX is KEF’s first three-way coaxial architectural speaker model with the patent-pending technology ‘Cavity Radiation Control’ designed to solve midrange issues found in typical three-way coaxial loudspeakers. Its unique open-backed midrange with acoustically absorptive foam design eliminates midrange distortion, up to 30dB midrange dip which is equivalent to 99.9% of reduced SPL. With Cavity Radiation Control, Ci250RRM-THX can deliver the highest mid-range acoustic realism in the market to date.

Another innovation is the implementation of the ‘Low Diffraction LF Aperture’ in Ci250RRM-THX. It is a carefully profiled, smoothed housing design for the Uni-Q driver array with an outer acoustically absorptive foam ring that reduces resonance and diffraction. The result is MF/HF performance while preserving bass output.

Ci250RRM-THX is also the first KEF architectural speaker with “Metamaterial Absorption Technology” (MAT). MAT is a highly complex maze-like structure that KEF says “will absorb 99% of the unwanted sound from the rear of the tweeter, delivering a more crisp, natural treble performance. Additionally, the 100mm (4 in.) Uni-Q driver array in Ci250RRM-THX is the

latest 12th generation, sharing many of the technologies found in the latest KEF Blade loudspeaker and the recently launched LS60 Wireless high-fidelity speaker system. Featuring a 250mm (10 in.) bass driver, Ci250RRM-THX delivers deep, room-filling bass. 

As a THX Certified Ultra architectural speaker, Ci250RRM-THX is engineered to create the immersive, high-fidelity audio experience even in large rooms and home theatres.

‘Hide your speakers, not your sound’ is the concept behind every KEF architectural speaker. Like all other models in the category, these two new additions are designed to be discreet in appearance and engineered with best-in-class acoustic performance, delivering an immersive soundscape while the speakers blend into the interior. The combination of innovative engineering and sophisticated acoustic design ensures KEF architectural speakers offer the same compelling performance as its HiFi speakers.
