Invisible Series - Back Boxes
Back Box for Masonry Applications
Use the MBC wood and metal back boxes for installing Stealth’s invisible speakers into masonry walls or ceilings, and can be installed either after the masonry is set or before to avoid chipping out a location in the masonry. 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 sides with 3/4” (19mm) plywood to provide solid mounting surfaces for the speaker panel.
