Abstract:
An acoustic transducer including a sound producing cone that is activated by a voice coil cylinder having a pair of spaced electrical windings that are retained in spaced relationship from a surround ferromagnetic ring that is carried by a heat sink and wherein a magnetic subassembly is mounted within the voice coil cylinder. The voice coil cylinder is supported by a pair of spaced suspension members or spiders and by the sound producing cone.
