Abstract

A phasing plug for a compression driver includes a body having an inlet side with a front surface and an outlet side with a rear surface, the body disposed about a central axis. A plurality of channels are formed through the body from the inlet side to the outlet side, each of the plurality of channels having an annular configuration with an entrance at the front surface, an exit at the rear surface, and a path length between the entrance and the exit. The plurality of channels have unequal path lengths such that acoustical signals traveling through the plurality of channels form a convex wavefront at the outlet side of the phasing plug.
