DD Audio 608f-D4

The 600f Series offers a wide range of DD AUDIO’s most popular Power Tuned Subwoofers, engineered for exceptional power handling and designed 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 in this latest "f" revision, precision-engineered thermal cooling improvements play a major role—along with design elements that are quite literally cutting edge.

THERMAL TRANSFER
The "f" revision subwoofer was specifically developed to deliver improved thermal transfer. The dual aluminum heat sink works to dissipate heat from soft parts into open chambers where the Free Flow Cooling System channels cooler induced air to remove this heat.

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

TALLER SURROUNDS
Increased Xmax and excursion required upgrades to the moving system—taller surrounds have been newly tooled and the spider refined to fully match 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-term durability.
