The KEF Ci5160RLM-THX is a reference-grade architectural loudspeaker engineered to deliver true cinema performance from within your walls. Part of KEF’s acclaimed R Series, this 3-way in-wall speaker is designed for dedicated home theatre environments where power, precision, and immersive sound are essential. With THX® Certified Ultra status, it meets rigorous performance standards for large home cinemas, ensuring dynamic, distortion-free playback at reference levels.
Reference-Level 3-Way Design
At its core, the Ci5160RLM-THX features a sophisticated 3-way configuration. Four 160mm (6.5″) low-frequency drivers deliver deep, controlled bass with exceptional impact, while a 160mm (6.5″) Uni-Q midrange array ensures detailed vocals and seamless sound dispersion. At the center of the Uni-Q array sits a 25mm (1″) vented aluminium dome tweeter equipped with KEF’s Metamaterial Absorption Technology (MAT™), reducing unwanted high-frequency distortion for remarkable clarity and accuracy.
The carefully engineered crossover points at 640Hz and 2.6kHz provide smooth integration between drivers, creating a cohesive and natural soundstage. With a wide 150° nominal coverage pattern, listeners experience consistent performance across the entire seating area.
THX® Ultra Certified Performance
Certified to THX® Ultra standards, the Ci5160RLM-THX is capable of delivering cinema reference levels in rooms up to 3,000 cubic feet. With a maximum SPL of 110dB and recommended amplifier power of 50–350W, it offers the dynamic headroom required for explosive movie soundtracks and detailed musical passages alike.
Designed for Seamless Architectural Integration
Despite its commanding acoustic performance, the Ci5160RLM-THX is engineered for discreet installation. Its slim mounting depth allows it to integrate cleanly into standard wall constructions, while optional rough-in frames simplify pre-construction planning. Once installed, it sits flush within the wall, maintaining a refined and minimalist aesthetic ideal for luxury home cinema spaces.
