Weather resistance is maximized by coating the woofer cone in polypropylene and terminating its circumference in JBL’s WeatherEdge™, a seamless, rubberized extension of the woofer surround that provides added protection to critical transducer elements. The PEI tweeter diaphragm features liquid cooling. Zinc plated grilles resist rusting in the harshest conditions.
