Inverted Apex Surround

The Inverted Apex Surround replaces the older style high roll surround. This new surround design increases effective surface area of the cone by using half the width of an older style surround without sacrificing any excursion. Couple that incredible excursion with increased surface diameter and the result is exponentially increased SPL output.

Cool Under Pressure

Spider Plateau Venting is a mechanical cooling process that circulates hot air for cool air at the voice coil as the subwoofer continuously cycles. The constant movement of hot air out and cooler air in, targeted directly at the high temperature voice coil increases reliability and longetivity.

Radial Ribbed T-Yoke

The specially designed backplate on the 75 Series not only gives it an impressive stance, but acts as an additional medium to conduct heat away from the voice coil. The increased surface area of the backplate dissipates additional heat ensuring the 75 subwoofer plays with lower distortion for extended periods.
