Features
Overview: The Rockford Fosgate Punch P2D2-8 is an 8-inch subwoofer with dual 2Ω voice coils. The sub features a StampCast steel frame, quick-release compression terminals, a Kevlar fiber reinforced paper 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.
Steel Basket: The P2D2-8 subwoofer features a StampCast steel basket for added rigidity.
Compression Terminals: The P2D2-8 features spring post terminals which accommodate speaker wire up to 10 gauge.
CEA-2031 Compliant: Power handling on the P2D2-8 subwoofer conforms to CEA-2031 industry standards. This means the subwoofer has the capacity to handle its rated 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 approximately 7/8 of an inch.
Enclosure Compatibility
Sealed Box: Rockford recommends a sealed enclosure with an optimum internal volume of 0.23 cubic feet (from 0.2 to 0.3 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 0.65 cubic feet using one 2" diameter x 8" long port; this yields a tuning frequency of 38.5 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 33 Hz).
The Rockford Fosgate P2D2-8 replaces these items:
- Dual 2-ohm voice coils
- polypropylene cone with poly-foam surround
- 50-200 watts RMS power range

First set of 8's I've ever owned. Their so cute!Lol! I'm a big bass head so I wasn't sure what to expect, but not disappointed. These lil' subs hit some incredible low notes. Highly recommend these subs for anyone wanting a clean bass sound,but not to over powering.
