Ci160RR-THX Round
THX ULTRA Certified 160mm Round
Ci160RR-THX is an ultra-high-performance loudspeaker featuring KEF's signature Uni-Q technology, designed for discreet in-ceiling or in-wall installation. As part of the Ci-R Series and a THX® Certified Ultra architectural loudspeaker, Ci160RR-THX is engineered to maintain exceptional sound quality at high outputs.

Ci160RR-THX
Ci160RR-THX’s Uni-Q® array boasts a 25mm high frequency tweeter mounted in the acoustic centre of a 165mm woofer, delivering the same, natural performance across the entire listening area. Plus, a Universal Cut-out system means its opening is the same as any 160mm KEF speaker for ease of installation and component selection.
THX ULTRA Certified
Ci160RR-THX is an in-ceiling speaker certified to THX ULTRA2 standard. 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.
THX certified in-ceiling speakers deliver the appropriate frequency response and high output and imaging quality of a traditional box speaker. This provides the best of both worlds - THX surround sound performance from components that blend harmoniously with any room decor.
Fast and Easy to Install
KEF's Ci loudspeaker design makes them so quick and easy to install that once the wire is run and the hole is cut in your wall or ceiling you can be listening to music in less than two minutes.
