1. An arrangement of electroacoustic transducers comprising in combination, a plurality of similar electroacustic transducers each having a central axis normal to a substantially planar, peripheral front surface, an annular frame member for each transducer, having a planar rear surface conforming approximately to said peripheral front surface of each said transducer and having an annular opening therein sized and shaped to correspond with the peripheral outline of a respective said transducer, means mounting and securing each said transducer with the peripheral front surfaces thereof abutting said planar rear surface of a respective frame member, attaching means extending outwardly from the sides of each said frame member adjacent the rear surface thereof, for angular attachment of adjacently disposed frame members one to the other to form a polyhedron whereby said frames are situated to define the faces of said polyhedron, said attachment occurring at equispaced locations around the perimeter of each of said frames and coaxial with the central axis, said attachment means disposing the planes of said frames in an equal angular relationship with one another whereby adjacent axes of said frames and corresponding transducers diverge at an approximately equal angle from a central point, said transducers being excited in phase.
