BRING THE THEATRE HOME WITH KEF’S NEW Ci5120QLM-THX and Ci3120QLM-THX ARCHITECTURAL SPEAKERS 

MAIDSTONE, KENT, UK – 13 November 2025: Since 1961, KEF has been committed to reproducing sound in its purest form – just as the artist intended. With decades of experience in acoustic innovation, the new Ci5120QLM-THX and Ci3120QLM-THX speakers, part of the Extreme Home Theatre range, feature advanced technology from KEF’s premium ranges to deliver sound with remarkable detail and depth, ensuring an engaging experience in any living space. 

Setting a new standard for architectural speakers, KEF pushes the boundaries of technology to ensure best-in-class acoustic performance, impeccable design and easy installation. For those looking for a high-performance home theatre set-up within a multipurpose room, the Ci5120QLM-THX and Ci3120QLM-THX are built to the same high standards expected from KEF, these speakers guarantee exceptional sound quality, and the compact size makes them perfectly suited for both dedicated home cinemas and living rooms. 

12th generation Uni-Q driver array with MAT 

At the heart of Ci5120QLM-THX and Ci3120QLM-THX sits KEF's signature driver array – Uni-Q. Now in its 12th generation, this remarkable feat of engineering acts as a point source, dispersing sound more evenly, allowing everyone to experience the same natural, detailed sound, wherever they are in the room. 

These speakers benefit from another groundbreaking 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 crisper, more natural treble performance. Whether listening to music or watching movies, everything is startlingly clear and breathtakingly realistic.

Room-filling, high-fidelity sound 

Both the Ci5120QLM-THX and Ci3120QLM-THX feature specially designed 120mm (4.75 in.) bass drivers that offer long throw capabilities and very low distortion, delivering deep, clean bass even from a compact driver. The Ci5120QLM-THX contains four bass drivers, while the Ci3120QLM-THX has two. 

This latest collection also includes KEF’s Flexible Decoupling Chassis, which reduces unwanted driver basket motion, ensuring vibrations from the mid and high-frequency motor systems do not interfere with performance. Additionally, the re-engineered tweeter gap damper effectively tames resonances, significantly enhancing detail and clarity. The 3-way system design and fully optimised crossovers allow each driver to be optimally configured for its specific role, elevating performance to another level. 

The Ci5120QLM-THX and Ci3120QLM-THX deliver breathtakingly realistic, completely immersive, cinematic sound. The speaker systems carry various THX^® certifications for exceeding the rigorous requirements for output levels, frequency response, signal-to-noise ratio, distortion, and recreating high-impact cinema sound with best-in-class audio fidelity. The Ci5120QLM-THX carries the THX Certified Ultra designation, making it suitable for large-sized rooms, and the Ci3120QLM-THX carries the THX Certified Select designation, making it compatible for medium-sized rooms. With these exceptional capabilities, these architectural speakers are perfect for music, gaming, TV, and films, providing an elevated audio experience in various spaces. 

Hide your speakers, not your sound 

Beyond the outstanding performance, Ci5120QLM-THX and Ci3120QLM-THX have been designed to be discreet. The Ultra-Thin Bezel (UTB) offers the slimmest visible rim around the speaker, ensuring a sleek appearance, and the paintable magnetic metal grille will seamlessly blend into the room’s interior design. Furthermore, they are IP64 certified, making them splash and dust proof, perfect for various environments.
