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.
Aluminum Voice Coil
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
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.
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 1.25 cubic feet (0.9-1.75 cu/ft acceptable)
- A ported enclosure with an
internal volume of 2.0 cubic feet (1.5-2.75 cu/ft acceptable) with a 4" diameter x
10.75" long port
