Sometimes a woofer comes along that changes the game. The R3 is just that; it has a high roll surround for an extended excursion. With a 4-Layer voice coil and a gigantic motor structure, it can handle some serious authority. This woofer can get down and hang with just about any other woofer out there with incomparable sound quality. Whether an SPL competitor or an SQ competitor, this is a woofer that can do it all.

Reference R3 Woofers use fiberglass stranding woven together for ultimate strength and less elasticity. A heavy soaking in epoxy combined with sonic qualities of pulp paper backing process itself worth of any system.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Subwoofer Wiring Diagram
