About the Ci250RRb-THX
The KEF Ci250RRb-THX is a passive, high-output in-wall or in-ceiling architectural subwoofer designed for discreet home theater and distributed audio installations. It uses a 250 mm (10 in.) extra-long-throw bass driver and is THX Ultra certified. KEF lists it as part of the Ci series and it remains present in current KEF document listings, so it does not appear to be discontinued.
