THX ULTRA Certified


Ci160RR-THX is an in-ceiling speaker certified to THX ULTRA2 standard. A deep understanding of the filmmaking process and surround sound is at the very heart of every THX certified 2.1, 5.1, and 7.1 speaker system. Engineered with design characteristics of professional studio speakers, THX recreates the tonal balance of the filmmaker's final mix in your living room. The results? Action sequences are impactful, and dialogue-driven moments are natural and engaging.

THX certified in-ceiling speakers deliver the appropriate frequency response and high output and imaging quality of a traditional box speaker. This provides the best of both worlds - THX surrounds sound performance from components that blend harmoniously with any room decor.
