KEF Ci3160RLb-THX In Wall Speaker

Hide your speakers, not your sound.

KEF's Ci range boasts a crisp, clear sound that creates a truly immersive experience.
Sold as a single speaker.


For music or movies, your installation needs to deliver the flawlessly accurate three-dimensional sound you’d expect from the best conventional speakers – startlingly clear and breathtakingly realistic. And that’s exactly what our Ci range does.

For the ultimate in Extreme Home Theatre, certified to THX ULTRA2 and THX SELECT2 standards, the formidable new Ci R Series Ci3160RLb-THX in-wall subwoofer has the deep bass and theatre thumping output capabilities of a traditional KEF subwoofer coupled with the ability to deliver all the drama and emotional intensity of full theatre sound quality.

With three high-output 160mm sub-bass drivers mounted to a massive aluminium baffle the Ci3160RLb-THX must be matched with KEF’s powerful KASA500 system amplifier. Each KASA500 can power up to two of the Ci3160RLb-THX subwoofers for even the most demanding theatre installations.

For theatre building flexibility, the remainder of KEF’s Extreme Theatre suite consists of two THX Ultra2 certified in-wall LCR speakers, a THX Ultra2 certified in-ceiling LCR speaker, as well as a smaller in-wall subwoofer and smaller in-wall LCR.
