The aluminum cone acts as a giant heat sink, directing heat away from the copper-clad aluminum voice coils. Special venting keeps the voice coils cool, so you get incredibly consistent bass performance over time. This P3 sub features an extended pole piece and bumped backplate that leaves more room for heavy excursion, so it’ll hit deeper lows without “bottoming out.”

The dual 4-ohm voice coils allow you to wire the sub for 2-ohm impedance to get maximum power output, or for 8-ohm impedance if you’re using multiple subs. The P3D4-15 sub works equally well in a sealed or ported enclosure, so you can choose the kind of bass you want for your system.
