Let Rockford Fosgate throw a "Punch" and lesser subwoofers will throw in the towel! That's because the redesigned Rockford Fosgate Punch HE2 RFP4212 12" subwoofer produces the kind of bass that's a pure knockout. The thump comes from a cone made from rugged yet responsive polypropylene. The result — the kind of bass extension, definition, and power that you expect from Rockford Fosgate.

A large roll treated foam surround guarantees more cone travel for more bass, while a stepped basket makes sure that the cone doesn't "bottom out." Choose the hook-up option that's right for you with dual 2-1/2" 4-ohm voice coils.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.

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.

Features

Dual Voice Coils: For increased system flexibility, the woofer has two 2-1/2 inch 4-ohm voice coils. When the voice coils are wired in parallel, the woofer presents a 2-ohm load. When the voice coils are wired in series, the woofer presents an 8-ohm load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 4-ohm load.

BART Foam Surround: The BART surround has a large roll to assure maximum cone travel. By increasing cone travel, the BART surround allows the woofer to produce more bass.

Aluminum Voice Coil Formers: The voice coil formers are aluminum for highly efficient heat transfer. This allows the use of multiple layers of high temperature copper windings for improved efficiency, and it improves power handling by effectively dissipating heat away from the voice coil windings.

LXcursion Stamped Basket: The Punch woofers use a durable and lightweight stamped cold rolled steel basket. To help prevent the spider from hitting the bottom of the basket ("soft bottoming"), the LXcursion basket features a deep step that moves the physical boundaries of the basket further away from the spider; this allows the cone far greater travel and, therefore more bass, without soft bottoming.

Hyper-Extended Pole Piece: The pole piece is extended in length to lower distortion and provide better low frequency response by operating the voice coil in a linear fashion throughout its travel in the magnetic field.

Vented Bumped Back Plate: The back plate has been bumped to allow the woofer more room for excursion without bottoming out. Additionally, "Aerovent" cooling efficiently and quietly circulates cool air around the voice coil. By keeping the voice coil cooler, power handling is improved.

CONsealer Gasket: A newly designed front gasket conceals mounting screws and provides an airtight seal between the woofer frame and the mounting surface. A better seal increases the amount of bass due to the elimination of air leaks.

Rubber Magnet Boot: A black rubber boot covers the exposed edge of the magnet structure to improve the cosmetics of the woofer and protect the magnet during installation. The rubber boot looks great when the woofer is mounted in an enclosure with a window that allows you to see the back of the woofer.

Binding Posts: The speaker terminals are spring loaded binding posts. The binding posts will accept pin connectors or bare wire up to 10 gauge.

Specifications

Recommended Sealed Box Volume: The sealed box volume range recommended by Rockford Fosgate is 0.9 cu/ft to 2.79 cu/ft. Within this range, the ideal size recommended by Rockford Fosgate is 1.25 cu/ft, so this is the enclosure recommended by Crutchfield.

Recommended Ported Box Volume: The ported box volume range recommended by Rockford Fosgate is 1.75 cu/ft to 4.0 cu/ft. Within this range, the ideal size recommended by Rockford Fosgate is 2.0 cu/ft, so this is the enclosure recommended by Crutchfield. One 4" diameter x 10.75" long port should be used with a 2.0 cu/ft enclosure. This tunes the box to 35 Hz.

Power Handling: The woofer has two 4-ohm voice coils, and each coil can handle up to 200 watts RMS (400 watts peak).
