About the Rockford Fosgate P3D2-15

Exploded view

Designed for deeper, louder bass

Rockford Fosgate designed the P3D2-15 15" subwoofer to stay strong even when the bass gets hot. This Punch P3 sub features a rigid anodized aluminum cone that holds its shape through heavy play, while staying light and responsive. Rockford Fosgate uses a new technique to attach the oversized rubber surround to the cone that increases available cone area up to 25%, so this sub can push more air for even bigger bass.

Heat-sink cone

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 2-ohm voice coils allow you to wire the sub for 1-ohm impedance to get maximum power output, or for 4-ohm impedance if you're using multiple subs. The P3D2-15 sub works equally well in a sealed or ported enclosure, so you can choose the kind of bass you want for your system.

Product Research

Enclosure Compatibility


Overview: The Rockford Fosgate Punch P3D2-15 is a 15-inch subwoofer with dual 2Ω voice coils. The sub features a hybrid StampCast basket, quick-release compression terminals, anodized aluminum cone, and Santoprene surround. An anodized aluminum voice coil former and spider venting help keep the subwoofer cool.

Dual 2Ω Voice Coils: The dual 2Ω voice coils offer wiring flexibility; when wired in parallel the woofer presents a 1Ω load, when wired in series the woofer presents a 4Ω load.

Compression Terminals: The P3D2-15 features spring post terminals which accommodate speaker wire up to 10 gauge.

CEA-2031 Compliant: Power handling on the P3D2-15 subwoofer conforms to CEA-2031 industry standards. This means the subwoofer has the capacity to handle power under continuous demand, not instantaneous power handling, that over time, can damage voice coils.

FlexFit Basket: The Flex Fit frame utilizes slots (where possible) instead of single screw sized holes; allowing slight adjustment of the speaker when mounted.

Trim Ring: To improve the cosmetic look, a decorative trim ring is included that mounts over the flange of the woofer. When using the cast aluminum trim ring the woofer is first mounted with four screws, then the ring is placed on top of the woofer, aligning the final four holes of the woofer with ring. The other four screws are used for these holes to mount the ring and woofer to the enclosure. Without the trim ring the mounting height of the woofer is just under an inch, with the trim ring it's approximately 1-1/16 inches. The diameter of the trim ring is approximately 16-3/8 inches.

Enclosure Compatibility

Sealed Box: Rockford recommends a sealed enclosure with an optimum internal volume of 1.58 cubic feet (from 1.5 to 3.0 cubic feet is acceptable). Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.

Ported Box: Rockford recommends a ported enclosure with an internal volume of 2.66 cubic feet using one 4" diameter x 10" long port; this yields a tuning frequency of 32 Hz. Ported (or vented) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from less power. However, this efficiency comes at the expense of very low frequency output (below 30 Hz).

Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

Box volume when running 2 p3 D215 sealed box common air?
[ Brian  Jun 04, 2017 ]
1 answer
Rockford recommends a sealed enclosure with an optimum internal volume of 1.58 cubic feet for a single 15" P3D2 subwoofer; when using two you can simply double that number which comes out to 3.16 cubic feet total volume for dual subs. If you would like to discuss further, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat. Thanks! My Bio:
