A double voice coil features two separate coils instead of the usual single coil, allowing different signals to be input into each coil. This design enables a single speaker unit to reproduce two sounds simultaneously, or to handle separate signals from different amplifiers. It also supports single-coil operation. By leveraging impedance variations, it can be used for volume adjustments, frequency response changes, and even matrix connections for achieving complex acoustic effects with multiple units.
