Metal Back Box (masonry applications)_|_Fits Speaker: LR116 (MBC16)

Use the MBC wood and metal back boxes for installing Stealth’s invisible speakers into masonry, hat channel, or other instances where a support structure is needed for Stealth invisible speakers. MBC boxes can be installed before masonry work is completed, or cut and fitted into existing masonry work.  The wood portion of the box provides a stable and secure attachment point for the speaker while the outer metal shell provides protection from the surrounding masonry.

Constructed of 1.2 mm thick metal, MBC back boxes are shipped fully assembled. Convenient knockouts for conduit are provided, 1 each on the top and bottom of the box. The knockouts will accept 1/2” (13 mm) conduits and loom clamps. The MBC back box is lined on all four edges with 3/4” (19mm) plywood to provide solid mounting surfaces for the speaker panel.
