Features

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.

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, the back plate is vented to circulate cool air around the voice coil. 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.

Binding Posts: The speaker terminals are spring loaded binding posts. The binding posts will accept pin connectors or bare wire up to 10 gauge.

Enclosure

Recommended Sealed Box Volume: The sealed box volume range recommended by Rockford Fosgate is 0.625 cu/ft to 1.5 cu/ft. Within this range, the ideal size recommended by Rockford Fosgate is 0.75 cu/ft, so this is the enclosure recommended by Crutchfield.

Recommended Ported Box Volume: The ported box volume range recommended by Rockford Fosgate is 0.75 cu/ft to 1.75 cu/ft. Within this range, the ideal size recommended by Rockford Fosgate is 1.0 cu/ft, so this is the enclosure recommended by Crutchfield. One 3" diameter x 13.25" long port should be used with a 1.0 cu/ft enclosure. This tunes the box to 35 Hz.
