The Gold Series delivers incredible musicality, utilizing a large-diameter, progressive-roll spider for increased linearity, and a large, ribbed Santoprene surround for high excursion and distortion-free, loud bass. The iconic KICKER Gold dust cap is integrated into the cone structure for incredible stability under the stress of high-powered music. This commemorative edition hoped to take you back with its ‘80s look, but you can be guaranteed the performance is all 21st century! KICKER engineers added Forced-Air Cooling to help it run more than 20 percent cooler than other subs.
