DD Audio 812f-D1

The 800f Series offers a wide selection of DD AUDIO’s most popular Power Tuned Subwoofers, designed for outstanding power handling and built to be a serious bass enthusiast’s daily companion.

REVISION 'F'
Previous revisions of the 600, 700, and 800 Series subwoofers made them bigger and better. In this latest “f” revision, precision-engineered thermal cooling improvements play a crucial role, along with several design features that are quite literally “cutting edge.”

THERMAL TRANSFER
The “f” revision subwoofer was specifically designed to deliver enhanced thermal transfer. The dual aluminum heat sink works to draw heat away from soft parts into open chambers, where the Free Flow Cooling System pushes through cooler induced air to dissipate the heat.

MORE XMAX
With the top plate thickened, the voice coil was extended to keep more winding in the magnetic gap. More coil wire surrounded by both motor steel and billet aluminum pulls away more heat under all conditions, optimizing electrical efficiency during prolonged use.

TALLER SURROUNDS
Increased Xmax and excursion demanded improvements in the moving assembly. Taller surrounds were tooled, and the spider refined to fully optimize the new motor design. These taller surrounds are double-stitched to fiberglass-woven, non-pressed cones. With dual layers and multiple spiders, DD continues its tradition of long-lasting durability.

Recommended enclosure: 49–85 liters (ported)
