Abstract
A dual compression driver includes a first driver assembly having a first annular diaphragm disposed about a central axis and a first phasing plug disposed coaxially below the first annular diaphragm with a first plurality of apertures extending therethrough, and a second driver assembly having a second annular diaphragm disposed about the central axis and a second phasing plug disposed coaxially above the second annular diaphragm with a second plurality of apertures extending therethrough. A shared annular magnet is disposed between the first driver assembly and the second driver assembly. A back cover is mounted to the first phasing plug, and a front adapter is mounted to the second phasing plug and includes a hollow conduit formed therein defining a circular exit of the dual compression driver. Acoustic signals from the first and second pluralities of apertures merge and radiate through the hollow conduit to the circular exit.
