Our take on the Rockford Fosgate Punch P1S4-12

by Jo Greene
Rockford Fosgate

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

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 P1S4-12 12" 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 P1S4-12 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 P1S4-12 is a 12-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 P1S4-12 subwoofer features a StampCast steel basket for added rigidity.

Compression Terminals: The P1S4-12 features spring post terminals which accommodate speaker wire up to 10 gauge.

CEA-2031 Compliant: Power handling on the P1S4-12 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 13/16 of an inch.

Enclosure Compatibility

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 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).

Great sub

Written By Pat, Harrisonburg, VA on Monday, May 19, 2014
 
Love this speaker. My only complaint is that the clearance between the speaker cover and the speaker itself is tight. I worry that the speaker will rub up against the cover and produce a hole. Other than that, no complaints. Sounds amazing!!
Pros:
good build quality sounds amazing
Cons:
tolerances may be to tight?

You will not find a better sub in this price range. I have had and punished many subs since 1986 and I always go back to Rockford Fosgate.

Hits loud ;D

Written By Nathan, Leesport, PA on Wednesday, May 09, 2012
Crutchfield Customer Review (What's this?)
 
The sound is freaking loud for only spending $160 simply because they are efficient enough and big enough in the box I chose Has a nice grille available that goes between speakers and outer grille to protect speaker even though i don't need cause the box is sealed for front of speakers
Pros:
Perfect value for such loud sound, clear bass in this band pass box or whatever it's called
Cons:
I'm not really going to consider this a negative, but the trim rings are a tight fit at 13in diameter, fits great in the box tight for anyone who needs to know

small price that hits nicely

Written By Anonymous, Toronto Ontario on Thursday, February 23, 2012
 
purchased 2 12's for $100 each. I have them in a bassworx ported box with a alpine m500 amplifier wired @ 2 ohms (roughly around 250 watts per subwoofer). i wasnt expecting a whole lot from these since they're only stage 1's. but after testing it in my car, they pound pretty hard for what they are. they get loud for a cheap price.
Pros:
- looks cool - hits hard
Cons:
- sq isnt all that great
