3" Black Aluminum Former
Extended Pole Piece
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 provides the
sub with improved power handling by efficiently 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 Immortal Series subs come in quad 2 ohm
coil configurations.
