For adjustably mounting an enclosure (10) such as a loudspeaker to an architectural mass such as on a wall (14), a ball-and-socket swivel mounting mechanism is enclosed within a rear region (10A) of the enclosure (10), thus eliminating unsightly conventional external swivel-mounting apparatus. A mounting ball (12A), at the end of a shaft (12B) cantilevered to the wall (14), enters the mounting mechanism through a circular opening (10C) in a central region of the rear panel (10A) of the enclosure (10). The ball (12A) is clamped between a fixed jaw (20B) and a movable jaw (22) actuated by an adjusting screw (28) via which the jaw-clamping force can be applied, adjusted and released by a tool (26) inserted through an opening in the front of the enclosure (10) and directed by an internal guide tube (18B) to engage the adjusting screw (28); thus all installation, orientation adjustment, clamping in place and removal of the enclosure (10) can be performed conveniently from the front of the enclosure (10). |
