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.
