One low-frequency roar from the RFD2212 and those inferior subwoofers will be scrambling for cover. This Punch HX2 12" subwoofer is built with the famous Rockford Fosgate attitude — a no-compromises commitment to deep, powerful, and realistic bass.

The FIBERlock cone of treated cured paper is strong and light for high performance and excellent transient response. Those bass notes go down smooth, too, thanks to a durable Santoprene rubber surround that controls the cone's path for maximum excursion.

The cast aluminum frame basket reduces flex and resonance for greater accuracy, while aluminum formers allow the voice coils to dissipate heat quickly. The dual 4-ohm voice coils can be wired as a 2-, 4-, or 8-ohm load, giving you more options when hooking up your system.

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.

Found in storage in boxes an I forgot. Put them in my roadmaster wagon and listen up. Great quality after 2years in storage.

plain and simple this sub can bump. been my favorite for the two years i've had
it and still going. can handle the punch and long trips with no problems at all.

Product Research



Dual Voice Coils: For increased system flexibility, the woofer has two 3" 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 Santoprene Rubber 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. Santoprene is a durable and temperature tolerant rubber material that provides the consistent support needed for linear speaker cone motion. In addition, the damping capabilities of santoprene eliminate the transmission of sonic disturbances between the cone and the frame of the speaker, improving the accuracy of the woofer's low frequency response.

Punch LX Cast Basket: The woofer uses a cast aluminum frame that reduces frame flex and offers increased stability over a stamped steel frame. This frame offers the lowest coloration of sound due to the added strength. To help prevent the spider from hitting the bottom of the basket ("soft bottoming"), the LX Cast 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.

Aluminum Formers: The aluminum formers allow the voice coils to efficiently dissipate heat, resulting in improved power handling.

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.

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.

Punch LX Long Xmax Voice Coils:  The L-xtended winding coils allow the voice coil to stay in the magnetic gap longer, resulting in less distortion and more control. Combine the L-xtended coil with the hyper-extended pole piece and the result is a huge magnetic sweet spot and deeper, louder, cleaner bass.

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.

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.

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.

Spring Posts: The woofer has two sets of spring posts, one set for each voice coil. The spring posts will accept pin connectors and bare wire.

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


Recommended Sealed Box Volume: The sealed box volume range recommended by Rockford Fosgate is 0.8 cu/ft to 4.0 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 250 watts RMS (500 watts peak).
