    Exclusive design

The GT5-12 features a single 4-ohm voice coil and a vented motor structure, and offers 1100 watts of peak power handling. With its fully vented motor structure and rubber-coated tinsel leads, the GT5-12 can withstand even the most intense bass assault. And unlike competing entry-level subwoofers, the GT5-12 is based on a solid motor structure featuring two large magnets covered by the classic JBL® rubber ring.
