ABSTRACT:
A device for mounting a speaker cabinet to various structural supports such as a wall, ceiling, floor or corner is disclosed. The device comprises a strut having two telescoping mutually rotatable members, and means for interlocking the members to fix the length and orientation of the strut. A flange having a plurality of apertures is fixed to one end of the telescopic strut for mounting the strut to the structural support. The configuration of the flange may be adapted to the shape of the structural support. In one embodiment, a flat flange is provided for mounting to planar support surfaces. In another embodiment, the flange includes a central planar portion and opposed inclined portions defining a 90.degree. angle so that the flange can be used to mount the telescoping strut to a corner surface. A bracket is pivotably mounted to the other end of the strut and has a plurality of apertures for mounting to the speaker cabinet. One or more of the speaker mounting devices disclosed herein can be used to mount high fidelity speakers in various configurations in a variety of locations.
