Product Overview
The C2G CG39909 Speaker Mount for 6-Inch Ceiling Speakers is an all-steel enclosure and speaker support bridge system engineered for installation in plenum air-handling spaces where the ceiling cavity requires a fire-code-compliant speaker enclosure. Where ceiling speakers require a separate back enclosure box in air-handling plenum spaces, this mount provides the approved solution — eliminating the need to route the speaker through conduit or use non-plenum alternatives. Suited for 6-inch ceiling speaker installations in classrooms, conference rooms, and commercial AV environments with plenum ceiling construction.
Product Description

The all-steel enclosure design provides the structural support and plenum-compliant back box required for standard 6-inch ceiling speaker installations in air-handling ceiling spaces. The speaker support bridge allows the speaker to be secured within the ceiling tile cutout without separate mounting hardware in most ceiling grid systems.
Key Features
- Plenum Air-Space Compatible — All-steel enclosure approved for installation in plenum ceiling cavities as required by NEC.
- 6-Inch Speaker Compatibility — Designed for standard 6-inch ceiling speaker installations.
- Speaker Support Bridge — Secures speaker in ceiling cutout without additional hardware in most grid ceiling systems.
- Commercial Grade Construction — All-steel housing for durability in permanent commercial AV installations.
