<p>A horn driver (2) including a driver body (4) and pole piece (32) positioned therein. A throat (34) extends through the pole piece along a longitudinal axis through the horn driver. A housing (56), attached to the driver body, is positioned above an upper portion of the pole piece and spaced therefrom to define a diaphragm chamber (58). A diaphragm (78) is positioned in the diaphragm chamber above and spaced from the pole piece and below and spaced from the housing. The diaphragm is attached to the housing at a central support area (76). The diaphragm extends radially outward from the central support area to an outer peripheral edge, a voice coil support (82) along its outer peripheral edge with a voice coil. The spacing between the diaphragm portion and the pole piece increases continuously in a non-linear manner from a minimum spacing near the peripheral edge to a maximum spacing near the central support area.</p> |
