DD Audio 818f-D1

The 800f Series offers a wide range of DD AUDIO’s most popular Power Tuned Subwoofers, engineered for exceptional power handling and built to be the 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 major role—along with some design elements that are quite literally cutting edge.

THERMAL TRANSFER
The "f" revision subwoofer was specifically developed to deliver enhanced thermal transfer. The dual aluminum heat sinks work to draw heat away from the soft parts into open chambers, where the Free Flow Cooling System forces in cooler induced air to expel this heat.

MORE XMAX
As the top plate thickness increased, the voice coil was extended to keep more coil wire in the gap. With more coil wire surrounded by both motor steel and billet aluminum, heat is drawn away more efficiently under all conditions—maximizing electrical efficiency during long-term use.

TALLER SURROUNDS
The increased Xmax and excursion demanded improvements to the moving assembly. Taller surrounds were designed, and the spider was refined to fully optimize the new motor structure. These taller surrounds are double-stitched to fiberglass-woven, non-pressed cones. With dual layers and multiple spiders, DD maintains its legacy of long-term durability.

Recommended enclosure: 142–198 liters (ported)
