Aluminum Voice Coil Former

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.
THE RESULT: Improves power handling by efficiently dissipating heat
Flat Progressive Dual Laminated Spider
A flat progressive dual laminated spider is employed to provide
stronger suspension for the woofer. A secondary spider is fused to the
primary spider near the critical voice coil bonding point. The combi-
nation of these two spiders, in addition to the progressive rolls,
provides the ultimate in linear control for high excursion capability.
THE RESULT: Strengthens suspension for higher excursion capability

Dual Laminated Foam Surrounds

The RF Punch XLC Woofers employ a dual laminated foam surround
for the front of the woofer's suspension. Dual lamination improves
reliability by making the woofer mechanically stronger.
THE RESULT: Adds mechanical strength

Hyper-Extended Pole Piece

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 RESULT: Lowers distortion and provides better low frequency
response

Vented Bumped Back Plate

The back plate has been stepped deeper to allow the woofer more
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 circu-
lates cool air around the voice coil.
THE RESULT: More excursion and increased power handling
