Dual 4 ohm sub ( AKA DVC ) are woofers with two separate voice coils mounted on a cylinder connected to a common cone. These are most often interconnected so as to allow the woofer to handle a lower impedance load at it's optimal power capacity.

A single 4 ohm sub ( AKA SVC ) are subs that only have one voice coil ( single set of (+) & (-) terminals.
