In-Ceiling Loudspeaker

The CS308 Ceiling Speakers provide teachers and students with the clearest audio amplification in any room. Engineered with a frequency response for optimal vocal reproduction and multimedia presentations, these 30W two-way ceiling speakers create whole room audio immersion with superior coverage.

Their easy and fast flush-mount installation, spring-loaded terminals, pre-drilled mounting brackets to hang them from T-bar ceilings, and paintable grilles make them blend right into the architecture (indoor or outdoor installations) so they're heard, not noticed.

The CS308 are sold in pairs, built with rugged steel and UL fire-rated ABS plastic for durability and safety. Each package includes two speakers and two brackets (one pair of each). The CS308 Ceiling speakers are also available with the Califone Infrared Classroom Audio System.
