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 2.0" high temperature voice coil increases reliability and longetivity.

Radial Ribbed T-Yoke
The specially designed backplate on the S65 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 S65 subwoofer plays with lower distortion for extended periods.

Creative Audio employs Mobile Electronics Certified Professionals, and we support customers before and after the sale.
