Our take on the Rockford Fosgate Punch HX2 RFD2208
When it sounds like the drummer is banging on a piece of driftwood, it's time to add a subwoofer to your system and the RFD2208 is a great place to start. This 8" Punch HX2 sub won't take up a lot of room, but it'll get your music pounding with the fanaticism you expect from Rockford Fosgate.
It has a FIBERlock cone of specially-treated, high-performance paper stock that's tough and light, generating impressive sonic accuracy with industrial-strength durability. A Santoprene rubber surround provides maximum travel for the cone, so you're sure to get low, window-pounding bass.
You'll also appreciate the 2-1/2", 4-ohm dual voice coils they also can be wired for 2- or 8-ohm loads, depending on your system design.
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.Details:
- dual voice coil design (4-ohm impedance for each voice coil) for more flexibility in wiring your system.
- frequency response 40-200 Hz
- power range 130-400 watts RMS (200 watts RMS per voice coil)
- peak power 800 watts
- sensitivity 83 dB SPL
- top mount depth 4-13/16"
- sealed box volume 0.1-0.5 cubic feet
- ported box volume 0.1-0.75 cubic feet
- Recommended Q-Logic Box Type: 1
- 1-year warranty

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 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 0.1 cu/ft to 0.5 cu/ft. Within this range, the ideal size recommended by Rockford Fosgate is 0.33 cu/ft, so this is the enclosure recommended by Crutchfield.
Recommended Ported Box Volume: The ported box volume range recommended by Rockford Fosgate is 0.1 cu/ft to 0.75 cu/ft. Within this range, the ideal size recommended by Rockford Fosgate is 0.625 cu/ft, so this is the enclosure recommended by Crutchfield. One 2-1/2" diameter x 11-1/4" long port, tuned at 40Hz, should be used with a 0.625 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).
