Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
The cone is made with polypropylene, which provides durability while being
lightweight and rigid.
Dual Laminated Foam Surround:
This woofer is made with a dual laminate foam surround. Dual lamination improves reliability by making the woofer mechanically
Aluminum Voice Coil Former:
The voice coil former is 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
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
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.
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 sealed enclosure
with an internal volume of 1.25 cubic feet (1.25-1.75 cu/ft acceptable)
- A ported enclosure with an
internal volume of 2.0 cubic feet (1.5-2.5 cu/ft acceptable) with a 4" diameter x
10.75" long port
