At the CEDIA Expo/CIX show back in early September, Theory Audio Design introduced its ic5 In-Ceiling Loudspeaker.

The Calif.-based company states that its latest product is the little brother to its ic6 6.5-inch in-ceiling speaker, and Theory Audio Design says the speaker delivers high levels of performance from a small-aperture product.

“Theory customers have been waiting in anticipation for the ic5, but Theory’s brand promise is to not bring any product to market unless we know we can deliver the best performance available in any given product category,” comments Marc Bertrand, CSO for Theory Audio Design. “The ic5 is finally here and I can say with confidence we have kept our promise. I can’t wait for Theory customers to hear its performance capabilities.”

Theory Audio Design points out that integrators can use the ic5 In-Ceiling Loudspeaker for residential or commercial installations, surround sound or distributed audio. According to the company, through its sealed design and optional all-weather grille, the speaker offers installers a solution for outdoor applications including marine. The ic5 offers a maximum output of 108dB via advanced polymer compression drivers, and a 5-inch carbon fiber woofer. For large, distributed installs, the ic5 includes a switch-selectable 70-volt/100-volt transformer that can be driven direct by the company’s DLC Series Loudspeaker Controllers.
