DD Audio 815f-D1

The 800f Series offers a wide selection of DD AUDIO’s most popular Power Tuned Subwoofers, designed for exceptional 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, and this latest “f” revision brings significant precision-engineered thermal cooling improvements, along with design elements that are quite literally cutting edge.

THERMAL TRANSFER
The “f” revision subwoofer was specifically engineered to deliver improved thermal transfer. Dual aluminum heat sinks work to draw heat away from soft components into open chambers, where the Free Flow Cooling System pushes through cooler induced air to evacuate this heat.

MORE XMAX
As the top plate thickness increased, the voice coil was extended to keep more winding in the gap. More winding surrounded by both motor steel and billet aluminum draws more heat away from the coil under all conditions, optimizing electrical efficiency during extended use.

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

Recommended enclosure: 85–170 liters (ported)
