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 pole pieces provide additional cooling to the motor structure, resulting in an increase in the subwoofer’s thermal power handling capability.
