Abstract
An omnidirectional loudspeaker having an inverted dome diaphragm disposed operably connected to a motor assembly and a phasing plug mounted to the motor assembly. The phasing plug has a top portion facing a convex surface of the inverted dome diaphragm and a bottom portion extending downward from the top portion along the central axis with a plurality of concentric apertures extending therethrough. Each aperture has a predetermined radial width and is spaced a predetermined concentric distance from an adjacent aperture. The plurality of concentric apertures cooperates with a compression chamber between the convex surface of the inverted dome diaphragm and the top portion of the phasing plug. Each aperture has a predetermined radial width, is spaced a predetermined concentric distance from an adjacent aperture and extends through the phasing plug exiting at the bottom portion.
