The JBL Stadium Subwoofer combines two contrasting design styles in a single product, which the manufacturer likes to call a “Jekyll and Hyde” design approach. While the installation is traditional, a fibreglass cone and a satin-finished dust cap with a black chrome logo give these subwoofers a powerful yet discreet appearance. Nonetheless, their reverse mount installation makes them distinctively eye-catching. Powerline slashes between the three fins ensure maximum cooling.
