About the Rockford Fosgate P2D4-15

Standout performance

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.

Bulletproof bass

Engineers at Rockford Fosgate designed the P2D4-15 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.

Made for heavy excursion

This P2 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." Special venting keeps the copper-clad aluminum voice coils cool through heavy use for consistent bass performance over time.

The dual 4-ohm voice coils allow you to wire the sub for 2-ohm impedance to work with a mono sub amp, or for 8-ohm impedance if you're using multiple subs. The P2D4-15 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 P2D4-15 is a 15-inch subwoofer with dual 4Ω 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 4Ω Voice Coils: The dual 4Ω voice coils offer wiring flexibility; when wired in parallel the woofer presents a 2Ω load, when wired in series the woofer presents an 8Ω load.

Steel Basket: The P2D4-15 subwoofer features a StampCast steel basket for added rigidity.

Compression Terminals: The P2D4-15 features spring post terminals which accommodate speaker wire up to 10 gauge.

CEA-2031 Compliant: Power handling on the P2D4-15 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 15/16 of an inch, with the trim ring it's approximately 1-1/16 inches. The diameter of the trim ring is 16-3/8 inches.

Enclosure Compatibility

Sealed Box: Rockford recommends a sealed enclosure with an optimum internal volume of 1.58 cubic feet (from 1.3 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 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 32 Hz).

Q
Will this fit in a 14'' diameter box?

As far as the face where the sub is mounted, I wouldn't go any less than 16" or 17" for the length and width. The sub itself has a diameter of 15" and some room would be needed for mounting hardware. Hope this helps :)
