Product features

The DD Audio 815f D2 is a 15 inch 800 Series Power Tuned subwoofer with a 4 inch flat aluminium wire voice coil, rated at 2500W RMS and 7500W peak, in the dual 2 ohm version.

Big competition style systems kill subs through heat as much as excursion, especially in long sessions at high volume. The f revision adds a dual stage cast aluminium heat sink and back plate venting to pull heat out of the motor, plus a 25mm top plate and longer coil winding for 31mm of Xmax.

What it does

  • High temperature 4 inch flat aluminium wire voice coil
  • Cast aluminium dual stage heat sink
  • Taller stitched EROM surround
  • Non pressed fibreglass loaded pulp cone
  • Multi layer high excursion spiders with integrated tinsel leads
  • Direct connect 8AWG wiring
  • Cast aluminium basket

Fitment and what comes in the box

Needs a 350mm cutout and 267mm of depth, so it suits a custom ported box of 3 to 6 cubic feet. That suits a boot or wagon build rather than a ute behind the seat.

Ask us what comes in the box before you order.

Installation notes

A sub on this scale needs a serious amplifier, big power and earth cables and often a second battery. We spec the full system so the electrical side keeps up.

Warranty

This comes with the manufacturer's warranty through the Australian distributor. See the manufacturer's terms for details, plus our guarantees under the Australian Consumer Law.
