Abstract: An article holder for mounting an audio speaker to a support surface includes a pair of connector members, each mounted on separate mounting plates and each pivotally connected to opposite ends of a link for repositionally supporting the speaker in three dimensions of adjustability. Each pivot connection is releasably lockable in a fixed position. In one embodiment, the article mounting plate is rotatably connected to one of the connectors for 360.degree. rotation with respect to the associated connector. In another embodiment, the article mounting plate and the attached connector is selectively pivotal and lockable in one of a plurality of discrete angular positions with respect to the link.
