JBL GC2 dual 18" high performance subwoofer is specially designed for bars, clubs and music restaurants that require sound reinforcement, live sound amplification and advanced low-frequency response.

JBL GC2 features two innovative 18-inch dual voice coil woofer drivers, which possess long excursion capabilities and high-power handling, resulting in extended and powerful lower frequencies with minimal distortion. The utilization of Differential Drive® technology and magnetic gap neodymium magnet cone enables improved heat dissipation, lightweight construction, extended excursion capabilities, and enhanced low-frequency performance, thereby meeting the requirements of demanding applications.

JBL GC2 redefines the internal structure of cabinet, which uses "Baltic" birch wood panels to maintain lower low frequency performance and sustain large dynamic and high intensity output, making it ideal for top venues requiring advanced low-frequency response. For added convenience and versatility, JBL GC2 is equipped with removable double-layer feet (rubber + plastic), catering to fixed installations and supporting stacking applications in both horizontal and vertical orientations. The tilting connector box allows for a close fit to the wall without requiring additional space for cable installation. The NL4 Neutrik Speakon® connectors allow loop-thru connection of multiple speakers and system extension can be accomplished with minimum effort.

Presently available in China only.
