Description
Mount 8-inch ceiling speakers in plenum return air spaces safely and cleanly with the Valcom V-9915M-5, a single steel backbox designed for round or square speaker baffles with four cable knockouts for flexible wiring entry.
The Telecom Spot Expert Review
Plenum-rated metal backboxes are a code requirement in many commercial ceiling installations — when the area above a suspended ceiling serves as the return air path for the HVAC system, plastic speaker housings are not permitted and metal enclosures are required. The V-9915M-5 satisfies that requirement for 8-inch ceiling speakers with a steel construction that meets the physical demands of above-ceiling work. Four knockouts give the installer flexibility in routing wiring from any direction, which matters when working in a crowded plenum with existing conduit and ductwork in the way. Compatibility with both round and square baffles means this one backbox works across multiple speaker models in the Valcom line. Use the V-9914M-5 bridge alongside this unit to properly support the assembly in the ceiling grid.
