Features:

• Overview: The Rockford Fosgate Punch P1S2-12 is a 12-inch subwoofer with a single 2Ω voice coil. The sub features a StampCast steel frame, quick-release compression terminals, a Kevlar fiber reinforced paper cone, and NBR surround (Nitrile Butadiene Rubber). An anodized aluminum voice coil former and spider venting help keep the subwoofer cool.
• Steel Basket: The P1S2-12 subwoofer features a StampCast steel basket for added rigidity.
• Compression Terminals: The P1S2-12 features spring post terminals which accommodate speaker wire up to 10 gauge.
• CEA-2031 Compliant: Power handling on the P1S2-12 conforms to CEA-2031 industry standards. This means the subwoofer has the capacity to handle its rated power under continuous demand, not just instantaneously, 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 PVC 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. The trim ring increases the mounting height of the woofer to 7/8 of an inch and the frame diameter to approximately 13-3/8 inches.
• Sealed Box: Rockford recommends a sealed enclosure with an optimum internal volume of 1.02 cubic feet (from 0.7 to 1.8 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 1.79 cubic feet using one 3" diameter x 6" long port; this yields a tuning frequency of 36.3 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 32 Hz).
