DD Audio 710f-D2

The 700f Series offers a wide range of DD AUDIO’s most popular Power Tuned Subwoofers, designed for outstanding power handling and 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 are of great importance, along with some design elements that are quite literally “cutting edge.”

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

MORE XMAX
When the thickness of the top plate was increased, the voice coil was extended to hold more winding within the gap. More coil wire surrounded by both motor steel and billet aluminum helps to pull more heat from the coil under all conditions, optimizing electrical efficiency during extended use.

TALLER SURROUNDS
Increased Xmax and excursion required enhancements to the moving system. Taller surrounds have been tooled and the spider refined to fully optimize the new motor design. These higher 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: 35–42 liters (ported)
