Rockford Fosgate Punch HE RFP3406
Our take on the Rockford Fosgate Punch HE RFP3406 by Crutchfield's Steven Johnson
If you drive a sports car, compact pickup, or any smaller ride (or if you don't want bass that takes up lots of space), here's a sub that can deliver impressive performance from a very small enclosure. Rockford Fosgate weighs in with the Punch HE RFP3406, a 6-3/4" woofer designed for use in tight locations where a larger sub just won't fit. Its FIBERlock cone made from a high-performance, industrial-strength paper stock is light and super-tough for superior sound quality and resiliency.
The RFP3406's power handling is excellent, thanks to its 1-3/4" voice coil and 25-ounce magnet. The heavy-duty treated foam surround has a large roll to ensure maximum cone travel, while the LXcursion stamped steel basket features a deep step that allows more bass without bottoming out. The CONsealer front gasket hides the mounting screws and provides a tight seal between the frame and mounting surface. Leave to Rockford Fosgate to build a small sub that really kicks!Details:

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.
This woofer is designed to work best in the following enclosures:
- A small, sealed enclosure with an internal volume of 0.25 cubic feet (0.1-0.32 cu/ft acceptable)
- A ported enclosure with an internal volume of 0.35 cubic feet (0.3-0.5 cu/ft acceptable) with a 2" diameter x 8.625" long port
