ABSTRACT:
This loudspeaker mounting system provides an enclosure (10) which is intended for installation into a drywall ceiling (12). The enclosure (10) includes an upper wall (16), and an annular lower flange (18) interconnected by a cylindrical sidewall (20). The sidewall includes a circumferentially spaced generally tee-shaped slots (30) each receiving an individual support bracket member (32) having a generally ell-shaped forward portion (54) and a slotted rearward portion (56). Inwardly projecting threaded fasteners (52) are attached to the sidewall adjacent each slot (30) to receive the slotted transverse portion (56). When the bracket member forward portions (54) are inserted into the sidewall (20) the bracket members can be guided into engagement with the ceiling (12) so that the ceiling is sandwiched between the flange (18) and the individual bracket members (32).
