Abstract
A compression driver for an omnidirectional loudspeaker having an inverted dome diaphragm, a phasing plug having a top portion facing a convex surface of the inverted dome diaphragm and a plurality of concentric apertures that cooperate with the convex surface of the inverted dome diaphragm. Each aperture has a predetermined radial width and is spaced a predetermined concentric distance from an adjacent aperture converging at an exit of the phasing plug. The compression driver has a dispersion control assembly mounted to the bottom portion of the phasing plug along the central axis.
