JBL Single 12" Car Subwoofer GT Series

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.

For anyone who likes to crank it up in the car, the new JBL® 12" (305mm) high-output GT5-12 subwoofer is the real deal. The JBL GT5-12 subwoofer features a single 4-Ohm voice coil and a vented motor structure, and offers 1100 Watts of peak power handling. The GT5-12 also features JBL’s newest design, combining classic elements with modern ones. The high-end subwoofer will replace the JBL GT4-12 model.

Plus One

Plus One Technology
Plus One carbon-injected cones provide more overall speaker-cone area than other cones in its class. The result is a better low-frequency response and a greater ability to make those important musical notes that people often associate with larger speaker sizes.
