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.
