Abstract

A modular loudspeaker system of uniformly sized and shaped loudspeaker modules permits hanging of a plurality of the modules in a wide variety of desired configurations. Each module has a pair of side walls with recessed upper and lower marginal edge portions and an integrally formed reinforced connectable structure that spans between the recessed edge portions for reinforcement of the module across its side. When several modules are hung vertically, the vertically aligned reinforced connectable structures reinforce the system along its entire length. Three module types are disclosed, with one type adapted for removable mounting therein of a speaker horn via a quick release hub. Overall, the system provides optimum versatility in adapting to the acoustical requirements of a wide variety of performance venues.

Claims

1. A loudspeaker module especially adapted for reinforced connection in a system having a plurality of modules, comprising:

a rear wall;

top and bottom walls and two side walls extending forwardly from said rear wall and forming with said rear wall an enclosure defining an opening spaced forwardly of said rear wall;

at least one speaker mounted to said enclosure within the opening; and

a pair of reinforced connectable means for reinforcement of respective side walls of said loudspeaker module, each connectable means being an integral part of a respective one of said two side walls, each connectable means including at least one connector means for securement to another said module.

2. The loudspeaker module of claim 1 wherein each said reinforced connectable means further comprises:

two pairs of plates, each pair of plates being secured to a respective one of said two side walls inside the enclosure; and

two pairs of spaced braces, each pair of spaced braces interconnecting a respective pair of plates.

3. The loudspeaker module of claim 2 having aluminum plates and braces.

4. The loudspeaker module of claim 2 wherein each of the connector means comprises

a series of bolts securing each said plate to the respective side wall, and

an L-track connector secured to said plate for connecting to another said module.

5. The loudspeaker module of claim 1 wherein each said side wall has an outwardly directed planar surface and upper and lower marginal edge portions recessed from said planar surface.

6. The loudspeaker module of claim 1 wherein said top and bottom walls and said side walls define a rectangular forward opening and said rear wall is smaller than said forward opening, said top and bottom walls have a trapezoidal shape, and said side walls converge from said forward opening toward said rear wall.
