About the Rockford Fosgate P212D4
Step up and enjoy the big sound of Rockford Fosgate's Punch Stage 2 subwoofer. A molded polypropylene cone, heavy-duty foam surround, and stamped steel frame combine to ensure you'll enjoy reliable operation and heavy-duty bass.
The P212D4 10" subwoofer's dual voice coil design allows you to get the most out of your amplifier, whether you have a single sub or a multi-woofer system. However you use it, the sub's beefy internal parts ensure solid power handling and resistance to the heat buildup that can damage lesser speakers.
This pounder is optimized for big sound from small sealed or ported enclosures, a real plus if you've got limited space for a sub in your vehicle.

Woofer: The cone uses a parabolic injection molded polypropylene design. Polypropylene is lightweight and strong, giving the woofer high power handling and low distortion.
High Excursion Large Roll Surround: A large edge roll surround allows Punch woofers to produce 20% more linear excursion than standard surrounds, resulting in more bass output.
Anodized Aluminum Voice Coil Former: Aluminum voice coil formers offer superior heat dissipation over other commonly used materials. The hard-anodized finish on this 2" former increases its strength. These two factors combine to improve the overall power handling characteristics of the subwoofer.
Precision Stamped CRS Basket: Reinforced cold roll steel basket legs dampen unwanted resonance for better bass coupling.
Double Stacked Magnet Motor Assembly: The stacked magnet assembly is used to create a powerful linear motor with increased excursion capability for superior bass output.
Removable Magnet Cover: The cosmetic magnet cover can be removed when additional mounting clearance is required. With the magnet cover installed, the woofer has the following dimensions:
- Magnet Diameter: 8.048"
- Depth as top: 6.045"
Spring Posts: The heavy-duty spring posts will accept pin connectors and bare wire up to 10 gauge.
Concealing Ring: Once the subwoofer is mounted, the concealing ring can be installed to hide the mounting screws, giving the subwoofer a finished look. With the ring in place the mounting height increases to 0.805".
