Kef Ci200QSb-THX ceiling Speakers

Product Description

Experience immersive, high performance sound from above with the KEF Ci200QSb THX Ceiling Speaker, a premium architectural speaker designed for demanding home theater, Dolby Atmos and custom installation applications.

The Ci200QSb THX combines KEF's advanced Uni Q driver technology with a powerful 8 inch driver and Metamaterial Absorption Technology (MAT) to deliver clear, detailed and evenly distributed sound from a discreet ceiling installation.

The Uni Q driver array places the tweeter and midrange driver on the same acoustic axis, helping the speaker operate as a coherent acoustic source. This creates a consistent and spacious soundstage across a broad listening area, making it especially suitable for immersive overhead channels.

With THX Certified Ultra performance, the Ci200QSb THX is engineered for serious home cinema systems where accurate reproduction, controlled dynamics and high output are important.

Its architectural form factor allows the speaker to sit flush with the ceiling, while the discreet grille can be painted to match the surrounding interior.
