Abstract: A mount assembly for mounting a device in an opening of a mounting structure having a rear surface, the mount assembly comprising a shaft and right and left wings. The shaft is rotatably connected to the device and includes an outer surface and a number of grooves each extending radially around a portion of the outer surface. The wings are pivotably linked to and extend laterally from the shaft. A first tab of one of the wings is configured be unengaged from the grooves when the shaft is rotated from a first position to a second position so that the first and second wings are free to move longitudinally relative to the shaft. The shaft is configured to engage the first tab via one of the grooves when the shaft is rotated back to the first position to urge the first and second wings against the rear surface.

Abstract: An in-wall or ceiling speaker enclosure (10) having a predetermined air volume is provided, and includes a housing (22) designed to support a speaker assembly (18) between a pair of adjacent wall studs (12,14). The enclosure (10) also has an expandable air chamber (24) of predetermined volume operably coupled and in communication with housing (22). The enclosure (10) can be easily mounted within a pre-cut wall opening (32) of minimal size.
