About this detail

A ceiling-mounted loudspeaker is supported independently from the rigid structure above rather than hanging directly from the ceiling system. A steel back can houses the speaker with a perforated grill flush at the finished ceiling line. Support is provided by one center wire and a minimum of two twelve-gauge support wires splayed at forty-five degrees, anchored to the deck using a two-by-two by eight-gauge by ten-inch bent plate attached with two number-ten sheet metal screws per flute. Electrical feeds run through rigid or electrical metallic tubing conduit into a two-gang speaker junction box, transitioning to flexible conduit down to the steel back can.
