2 inch Treated Foam
The 2 inch treated foam surround is resilient to temperature
variations and provides the consistent support necessary for
the linear motion of the speaker cone. In addition, the
inherent damping capabilities eliminates the transmission of
sonic disturbances between the cone and the frame of the
speaker. This greatly improves the clarity of the speakers
frequency response.
Flat Spider
The speakers linear compliance is balanced through the use
of a flat spider design. A flat spider provides symmetrical
control of the voice coil through it's cone excursion. Linear
cone excursion reduces harmonic distortion for improved
sound quality. This allows for reduced mechanical distortion
for better sound quality.
Chrome Finish
Chrome has long been an industry standard in terms of
durability in protective metal finishes. We have spared no
expense in this area, and not only is it a protective finish, but it
is also a great addition to any plexi style enclosure.
Convex Dust Cap
The use of a convex dust cap is used to increase the cone
rigidity and improve power handling by forcing more air
through the voice coil. Added benefits include smooth
frequency response.
Aluminum Voice Coil
Extended Pole
Vented Oversized Back Plate
Voice Coil
The voice coil former is black, anodized aluminum for highly
efficient thermal transfer. This allows winding high temperature
copper wire in multiple layers for improved efficiency. This allows
for improved power handling by effectively dissipating heat.
The pole piece has been extended to provide a more linear magnetic
field for the operation of the woofer. This lowers distortion and
provides the woofer with better low frequency response.
The back plate has been stepped deeper to allow the woofer more
excursion without bottoming out. Additionally, the back plate is vented
with a radius aerodynamic back vent which efficiently and quickly
circulates cool air around the voice coil. This allows for more
excursion and higher power handling without damaging the sub.
The 4-layer, edge wound voice coil design of the speaker allows for
a variety of impedance loads to be configured when used individually
or matched with multiple subs. Please continue to the TECH TIPS
section of this manual for wiring diagrams and procedures. The cast
basket subs are dual 4 ohm voice coils.
