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.
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.
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.
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.
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.
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.
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.
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.
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.
This woofer is designed to work
best in the following enclosures:
- A small, sealed
enclosure with an internal volume of 0.25 cubic feet (0.1-0.32 cu/ft
- A ported
enclosure with an internal volume of 0.35 cubic feet (0.3-0.5 cu/ft
acceptable) with a 2" diameter x 8.625" long port
