Abstract: An electromagnetic transducer includes a diaphragm movable relative to a central axis, a magnetic assembly axially spaced from the diaphragm, and a magnetic gap annularly disposed about the central axis. A voice coil is coupled to the diaphragm and includes spaced first and second coil portions which are at least partially disposed in the magnetic gap. A housing includes a rear frame surrounding and supporting the magnetic assembly, the rear frame having an annular well portion in fluid communication with the magnetic gap. At least one channel is formed in the rear frame in fluid communication with the well portion and extends outwardly beyond the well portion in a radial direction. A vent is provided on an outer surface of the rear frame in fluid communication with the at least one channel, wherein air exits the transducer via the vent to transfer heat from the transducer to the ambient environment.
