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.

Acrylic Coated Spruce
Pulp Paper Cone: The
cone is made with spruce pulp paper. This provides the necessary combination of
weight and strength for high levels of output without cone breakup. The cone is
treated with a thermally cured acrylic emulsion that seals the cone body,
resulting in increased cone rigidity and lower distortion.
BART Foam Surround:
The large roll of the BART foam surround ensures maximum cone travel, resulting
in more bass.
The new Punch LXcursion basket features a deep step in the basket that allows
the cone to travel further without the spider hitting the bottom of the basket,
resulting in more boom.
Bumped Back Plate: The back plate has been stepped deeper to
allow the woofer more room for excursion without bottoming out. This enables the
speaker to be used in a smaller enclosure. Additionally, the back plate is
vented with a radiused aerodynamic back vent which efficiently and quietly
circulates cool air around the voice coil. By keeping the voice coil cooler,
power handling is improved.
Pole Piece: The pole piece has been extended to
provide a more linear magnetic field for woofer operation. This lowers
distortion and provides the woofer with better low frequency response.
L-xtended Voice Coil:
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.
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 improves power handling by effectively
dissipating heat away from the voice coil windings.
Diameter: The woofer is made with a 2.5" voice coil.
Progressive Dual Laminated Spider: A flat progressive dual
laminated spider is used to provide a stronger 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.
Concealer 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 elimination of air leaks. When the gasket is used the following dimensions change:
- Top Mount: 5.675"
- Frame Width/Length:
- Flange Height: 0.445"
Handling: The RMS and peak power specs listed under the specs
tab are for both voice coils combined. Each voice coil is rated to handle 200
watts RMS and 400 watts peak.
Type/Volume: The woofer is designed to work best in a small,
sealed enclosure with an internal volume of 0.75 cubic feet, or a ported box of
1.0 cubic feet (port dia 3", port length 13.25", tuned at 35Hz).
