About the Ci200QSb-THX
The KEF Ci200QSb-THX is a square, architectural in-wall/in-ceiling passive subwoofer sold as a pair. It uses a single 200 mm (8 in.) low-frequency driver and supports two installation approaches: passive operation through its internal 100 Hz crossover, or active operation with KEF’s KASA500 system amplifier. It is THX-certified and designed for discreet custom-install home-theatre bass reinforcement. KEF states that two pairs driven by one KASA500 meet THX Select2 performance requirements, while four pairs driven by two KASA500 amplifiers meet THX Ultra2 requirements. The speaker has an IP64 rating and can be used with the optional RIF200S rough-in frame. The product remains listed on KEF’s current product and documentation pages.
