A Versatile THX Certified Select Architectural Speaker with MAT™

Since 1961, KEF has dedicated itself to reproducing sound in its purest and most authentic form—exactly as the artist intended. Drawing on decades of acoustic innovation, the Ci-Q Series integrates advanced technology from KEF's premium lines to deliver sound with stunning clarity and depth, providing an engaging listening experience in any environment.

The Ci3120QLM-THX meets the increasing demand for high-performance home theater sound in multipurpose living spaces, where dedicated cinema rooms are becoming less common. Built with KEF's signature precision and quality, this model offers exceptional audio performance in a compact form, making it ideal for both home theaters and everyday living areas.

Equipped with KEF's 12th-generation Uni-Q driver array and revolutionary Metamaterial Absorption Technology (MAT), the Ci3120QLM-THX carries the THX Certified Select badge. This combination of cutting-edge design and acoustic engineering ensures crystal-clear, impactful sound—perfect for a wide range of applications.

12th-Generation Uni-Q Driver Array with MAT™

At the core of the Ci3120QLM-THX is KEF's renowned Uni-Q driver array, now in its 12th generation. Acting as a single point source, it disperses sound evenly throughout the room so every listener enjoys the same rich, detailed audio experience, regardless of where they sit.

The speaker also incorporates KEF's pioneering Metamaterial Absorption Technology (MAT)—a complex, labyrinth-like structure that eliminates 99% of unwanted sound from the rear of the tweeter. The result is remarkably pure, natural high frequencies with enhanced clarity.

Immersive, High-Fidelity Sound

The Ci3120QLM-THX includes two custom-designed 120mm (4.75 in.) bass drivers that deliver deep, precise low frequencies with minimal distortion, even from a compact enclosure. Working in harmony with the Uni-Q driver and MAT, the Flexible Decoupling Chassis minimizes unwanted vibrations, ensuring the mid and high frequencies remain clean and accurate.

An improved tweeter gap damper reduces resonance for enhanced detail, while the three-way system design and carefully tuned crossovers allow each driver to perform optimally within its frequency range.

Earning the THX Certified Select mark, the Ci3120QLM-THX exceeds strict standards for output level, frequency response, signal-to-noise ratio, and distortion. It delivers powerful, cinema-grade sound with stunning fidelity—ideal for medium-sized spaces and versatile enough for music, gaming, TV, or film.

Hide your speakers, not your sound

KEF's design philosophy inspired the sleek and discreet look of its architectural speaker range. The Ultra-Thin Bezel (UTB) design provides an elegant, nearly invisible edge around the speaker, while the paintable magnetic grille ensures it blends seamlessly into any wall or ceiling.

Additionally, the Ci3120QLM-THX is IP64-certified, offering protection against dust and splashes, making it suitable for use in a variety of environments without compromising on performance.
