About the Rockford Fosgate Punch HE2 RFP3212

"If we build it, it will thump." That's the principle Rockford Fosgate pours into their woofers. The Punch HE2 RFP3212 12" subwoofer is a prime example. The thumping comes from a cone made from FIBERLock — an industrial-strength, chemically-bonded paper stock that's treated with a special acrylic emulsion. The result is a sonically superior material that has exceptional damping and rigidity, for excellent bass extension and definition.

The result is a sonically superior material that has exceptional damping and rigidity, for excellent bass extension and definition.

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 that enable the sub to be wired from a 2- to 8-ohm load. 1-year warranty.

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.

Features

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

FIBERLock Cone: This new high performance paper stock is a combination of natural and regenerated cellulose fibers interlaced with a third, longer fiber. The three natural fibers are chemically fused together with a blend of three interactive binding agents. The extremely high fibril strength and toughness comes from the combination of all six of these component layers. FIBERLock is light, tough and it's proven to have superior sound quality and incredible durability. The cone is then treated with a Thermally Cured Acrylic Emulsion that seals the cone body for exceptional damping and even greater rigidity, resulting in industrial strength power handling.

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.

Dual Laminated Progressive Flat Spider: The dual laminated progressive flat spider provides a very strong suspension for the woofer. A secondary spider is fused to the primary spider near the critical voice coil bonding point. The combination of the two spiders, in addition to the progressive rolls in the spiders, provides the ultimate in linear control for high excursion capability.

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 using a back plate that is vented with a radiused aerodynamic back vent. 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. 

Enclosure Compatibility: This woofer can provide extended bass in sealed and ported enclosures (see the "Specifications" section for more information on enclosures).

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 10-3/4" long port, tuned at 35Hz, should be used with a 2.0 cu/ft enclosure.

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