Atlas Sound 8" Blind-Mount enclosure systems ( U.S. Patent # 4,673,149 ) provide an easy and cost-effective alternative for secure loudspeaker installation in retrofit ceiling applications. All necessary hardware is provided including a unique support system with mounting ears that telescope out from inside the enclosure and adjust vertically to accommodate ceilings with a thickness of 1/2" (13mm) to 13/8" (35mm).

Units feature CRS construction and include torsion-spring receptacles for quick mounting of torsion-spring grilles. (J-Nuts are included on the return of the enclosure to accommodate surface-mounting grilles.)

To allow cable access, enclosure backplates are manufactured with three 1/2" (13mm) conduit knockouts. Enclosures are also equipped with sound damping material to minimize metallic resonance.

Model BMT95-8-7 is a 7" (178mm) deep version which includes high-density fiberglass fill finished in a textured black epoxy.
