KEF’s newly introduced Extreme Home Theater speakers employ the company’s latest engineering concepts.

Extreme Home Theater Speakers Feature Latest KEF Technologies

KEF has recently introduced two new THX Certified models to their range of Extreme Home Theater architectural speakers – the Ci250RRM-THX and the Ci250RRb-THX. The Ci250RRM-THX is KEF’s first three-way coaxial architectural speaker with technologies that have been developed by KEF’s engineering team in Maidstone, U.K. to deliver the best possible sound. The speaker utilizes KEF’s patent-pending technology ‘Cavity Radiation Control’ to solve the midrange issues found in typical three-way coaxial loudspeakers. It also incorporates an open-backed midrange with acoustically absorptive foam to eliminate midrange distortion up to a 30dB midrange dip.

In addition to this, the Ci250RRM-THX has the ‘Low Diffraction LF Aperture’ design, which 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. This design results in exceptional MF/HF performance while preserving a tremendous bass output. Furthermore, the Ci250RRM-THX is the first KEF architectural speaker with Metamaterial Absorption Technology (MAT), which 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.

The Ci250RRM-THX features a 250mm (10 inch) bass driver and a 100mm (4 inch) Uni-Q driver array, which is the latest 12th generation and shares many of the technologies found in the latest KEF Blade loudspeaker and the recently launched LS60 Wireless high-fidelity speaker system. The speaker is also a THX Certified Ultra architectural speaker, engineered to deliver immersive, high-fidelity audio experience even in large rooms.

The Ci250RRb-THX, on the other hand, is designed to deliver incredibly accurate and powerful bass while remaining visually discreet. It features a 250mm (10 inch) bass driver with a massive 150oz magnet, making it capable of producing deep, powerful bass when driven by KEF’s DSP-equipped KASA500 amplifier. The Ci250RRb-THX is also part of the KEF Extreme Home Theatre line-up, making it ideal for use in a range of room sizes, including large home spaces.
