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