About the Rockford Fosgate Punch P1S4-15
Rockford Fosgate showcases their fanatical commitment to sonic excellence in the Punch Series of speakers, amps, and subs. If you like to listen to potent, powerful music — and feel it too — Punch components will give you impressive sound that'll stand out in a crowd.
Engineers at Rockford Fosgate designed the P1S4-15 15" subwoofer to dish out the kind of powerful low end you crave in your ride. Its responsive paper cone is reinforced with the same Kevlar® fibers used in bulletproof vests so you get the best of both worlds — warm bass that's exceptionally hard-hitting. 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.
The P1S4-15 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." This sub works equally well in a sealed or ported enclosure, so you can choose the kind of bass you want for your system.

Features
Overview: The Rockford Fosgate Punch P1S4-15 is a 15-inch subwoofer with a single 4Ω 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 P1S4-15 subwoofer features a StampCast steel basket for added rigidity.
Compression Terminals: The P1S4-15 features spring post terminals which accommodate speaker wire up to 10 gauge.
CEA-2031 Compliant: Power handling on the P1S4-15 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 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.
Enclosure Compatibility
Sealed Box: Rockford recommends a sealed enclosure with an optimum internal volume of 1.58 cubic feet (from 1.3 to 3.5 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 8" long port; this yields a tuning frequency of 34.4 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 34 Hz).

15 inch sub woofers deliver the deepest bass notes with the lowest distortion. The Rockford subs do this effortlessly and their power handling is great for such an economical speaker.
