What is a dual voice coil speaker?
A dual voice coil speaker is simply one in which two separate lengths of wire are wound together around the same former and terminated independently. Except for some exotic exceptions, both voice coils have the same number of turns and length of wire, resulting in identical electrical characteristics. In most cases, one coil is wound onto the former first, and the second one is wound over the first one. Naturally, it is more expensive to wind and terminate dual voice coils and you will typically pay a small premium compared to a similar single voice coil speaker.
