Product Description
The Ci5120QLM-THX in-wall architectural speaker meets the growing demand for high-performance home theatre solutions in multipurpose rooms, where dedicated spaces are less common. Featuring a 12th generation Uni-Q driver array and our groundbreaking Metamaterial Absorption Technology (MAT), the Ci5120QLM-THX is THX Certified Ultra. It recreates high-impact cinema sound with best-in-class audio fidelity, making it ideal for large-sized rooms.
Ci-Q Series
Since 1961, KEF has been committed to faithfully reproducing sound in its purest form – just as the artist intended. With decades of experience in acoustic innovation, the Ci-Q Series combines advanced technology from our premium ranges to deliver sound with remarkable detail and depth, ensuring an engaging experience in any setting.
12th generation Uni-Q®
At the heart of Ci5120QLM-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 in the room they are.
MAT™
The Ci5120QLM-THX also benefits 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.
Room-filling, high-fidelity sound
The Ci5120QLM-THX features four 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.
Together with the Uni-Q driver array with MAT, it includes KEF’s Flexible Decoupling Chassis, which reduces unwanted driver basket motion, ensuring that 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.
Hide your speakers, not your sound
The Ultra-Thin Bezel (UTB) offers the slimmest visible rim around the speaker, ensuring a sleek appearance. Designed to be discreet, these speakers feature a paintable magnetic metal grille that seamlessly blends into your wall. Each grille features an optional KEF logo plate, which can be removed for an even cleaner aesthetic. Furthermore, they are IP64 certified, making them splash and dust proof, perfect for various environments.
THX Certified Ultra
Carrying the THX® Certified Ultra designation, the Ci5120QLM-THX has exceeded the rigorous requirements for output levels, frequency response, signal-to-noise ratio and distortion. It recreates high-impact cinema sound with best-in-class audio fidelity, making it ideal for large-sized rooms. With its exceptional capabilities, it’s perfect for music, gaming, TV, and films, providing an immersive audio experience in various spaces.
A deep understanding of the filmmaking process and surround sound is at the very heart of every THX certified 2.1, 5.1 and 7.1 speaker system. Engineered with design characteristics of professional studio speakers, THX recreates the tonal balance of the filmmaker’s final mix in your living room. The results? Action sequences are impactful, and dialogue-driven moments are natural and engaging.
