Features

Woofers: This enclosure is loaded with two 8 ohm Rockford Fosgate Punch HE RFP3812 12" woofers and has a separate terminal cup for each woofer. When the terminal cups are wired in a stereo configuration, each channel of the connected amplifier will see an 8 ohm load. When the terminal cups are wired together in a parallel configuration and connected to a bridged amplifier, the amplifier will see a 4 ohm load. The power specs in the Crutchfield database are for 4-ohm mono operation. When wired in the 8-ohm stereo configuration, power handling is 200 watts RMS/400 watts peak per woofer.

Small Sealed Enclosure: The design of the enclosure is a small acoustic suspension system, which offers great low frequency reproduction while occupying minimal space.

Angled Back Panel: The enclosure's back panel is angled, resulting in a greater depth at the bottom of the enclosure than at the top. The angled back reduces standing waves in the enclosure and allows the enclosure to fit nicely against the back of the angled rear seat of most cars.

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.

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.

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.

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 it's travel in the magnetic field.

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.

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. 

5-way Binding Posts: The binding posts will accept pin connectors, spade connectors, banana plugs, dual banana plugs, and bare wire.

Crossover Recommendation: For the best result, a low-pass crossover with a cutoff frequency of 400Hz or less should be used with this enclosure.

Portability: The enclosure does not have handles, but the sides are recessed for easy portability.

Warranty Note

Warranty Note: The warranty only applies to the speaker, not the enclosure.
