Woven Fiber/Kevlar Reinforced Pulp Cone:
This Alpine Type-E subwoofer features a two-piece parabolic woven fiber and Kevlar reinforced pulp cone. Kevlar adds
strength and tear resistance to the woofer cone while maintaining the benefits
of a pulp cone design. The lightweight cotton fiber design provides a faster and
more dynamic response from the woofer.
Santoprene Rubber Surround: The high-excursion, tapered half-roll,
injection molded Santoprene rubber surround is durable and resistant to
the elements, resulting in a very reliable performance. The surround is
specially designed to resist deformation that is common in woofers with
wide surrounds. This design gives the surround more control over the woofer cone
to reduce distortion and possible driver failure.
Progressive Nomex Spiders: This subwoofer utilizes a Progressive Nomex spider for stability and mechanical
durability. The custom progressive roll gives the woofer a longer, more linear
stroke with maximum centering and restoring force. Special edge control design
and Nomex construction provide excellent tear resistance, strength and long-term
Voice Coil: The Alpine SWE-1043 features a 4-layer single voice coil
made from 180-degree high-temperature wire on an aluminum bobbin.
Airflow Optimized Extended/Vented Pole: This SWE-1043 features an
extended pole piece which provides optimum airflow for the woofer.
Custom High Strength Steel
frame is custom stamped from high strength steel.
Speaker Terminals: This Alpine Type-E subwoofer features a pair of
heavy duty push-terminals on one side of the woofer's basket that will
accommodate up to 8-gauge speaker wire.
Tinsel Leads: The Type-E subwoofer uses insulated 16-gauge stranded
Gasket Cover: Alpine uses a
Concealed Mount Gasket System to cover the mounting screws for a clean look. The
black rubber gasket ring comes already installed on the woofer and needs to be
removed before drilling the mounting screws (not supplied). The gasket ring then
snaps back into place once the woofer is mounted.
Protective Grille: The Alpine SWE-1043 Type-E subwoofer comes supplied
with a high impact protective grille. The black plastic grille snaps onto the
woofer without the need for any additional hardware. The rubber gasket cover
must be removed when using the grille. The grill also hides the mounting screws,
as well as protects the woofer. The grille adds 0.9725" to the woofer's height

from 1.0 cu/ft to 2.0 cu/ft. The ideal recommended volume is 1.35 cu/ft with a
1-1/4" x 11" x 22-1/2" (long) slot port.
