A compensation assembly for a mounted loudspeaker system includes a mounting frame having a spherical front socket; a retaining ring; a compensating back socket having a spherical back socket; and a woofer frame having a spherical ball structure that fits between the front and back sockets. The compensating back socket has an array of matching slots that align with and partially surround bosses of the mounting frame such that the compensating back socket is free to float in a vertical axis but is restrained from rotating around a central axis. The ball structure is held by a force applied to the compensating back socket by compressing deformable elements around the outer perimeter of the compensating back socket. The deformable elements may be integrally formed as molded-in-place polymer tensioning springs or separately formed as metallic elements.
