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
Four-Layer Voice Coil
Multiple layers of high temperature copper wire are wound on the
Aluminum Voice Coil for efficient thermal transfer. The massive voice
coil increases XMAX and adds to the moving mass of the speaker. This
lowers the Fs of the speaker for better low frequency response and
increases the power handling.
THE RESULT: Increases XMAX and power handling
Dual Laminated Foam Surrounds
The RF Punch Woofers employ a dual laminate 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
