New proprietary frame, unique in-board motor structure and new cone design deliver a woofer that is a full inch shallower than equivelent sized models from competing brands. This approach alllows for fit into more vehicles without a sacrafice in performance.Progressive spider provides better control at excursion limits and reduces woofer distortion.Hi-roll rubber surrounds provide exceptional cone edge suspension and long-throw linearity with the proper amount of control and stability at excursion limits.Vented polepieces provide additional cooling to the motor structure, resulting in an increase in the subwoofer's thermal power handling capability.
