Methods and apparatus for providing a heat sink for a loudspeaker

A phase plug for a horn loaded speaker has a frustro-conical body with a spherical entrance end and a planer outlet end. The plug is formed with radial channels. The entrance of the phase plug and the speaker diaphragm are conformal and the channels have generally equal aperture area from the entrance to the outlet, or slightly increasing aperture areas so as to minimize diffraction The truncation surface is defined by the intersection of the sidewalls of the conical body and the cone angle of the horn.
