KEF Ci200QSb-THX In-Wall Subwoofers (Pair)

PLEASE NOTE: these subwoofer drivers are passive and require external amplification. They will not work directly with a home cinema amplifier/receiver.

Certified to THX ULTRA2 and THX SELECT2 standards, the formidable Ci200QSb-THX in-wall subwoofer delivers deep bass and theatre thumping output capabilities, matched to the uncanny ability to deliver all the drama and emotional intensity of full theatre sound quality.

With a powerful high-output 200mm sub-bass driver, the Ci200QSb-THX can be used in passive mode to supplement the LF output of KEF’s Ci series in-wall or in-ceiling speakers.

In Active mode, when 2 pairs of the Ci200QSb-THX subwoofer are powered by the powerful 250W KEF KASA500 Subwoofer Amplifier the performance meets THX Select2 specification.

When 4 pairs of the Ci200QSb-THX are powered by 2 KEF KASA500 System Amplifiers the performance meets THX Ultra2 specification.
