Extreme Home Theatre
KEF’s Extreme Home Theatre system sets a new standard for architectural loudspeakers. Certified to THX Ultra2  standards, the formidable KEF Ci-R Series has the jaw-dropping acoustic capabilities of KEF’s award-winning speakers, delivering all the drama and emotional intensity of true theatre sound quality.
Design & Performance
THX certified in-wall 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.
Easy Installation
KEF Engineers have meticulously designed the Ci160RR-THX to be quick and easy to install without sacrificing baffle rigidity. KEF’s patented built-in wall bracket design allows for a damage-free installation every time.
UNI-Q® Driver Technology
KEF’s patented Uni-Q driver technology places the tweeter precisely at the acoustic centre of the bass/midrange cone, so both act together as a single source. Because Uni-Q disperses sound widely and evenly over a large area, KEF’s architectural speakers deliver effortlessly natural sound with minimal distortion to every person in the room.
