Hi-roll rubber surrounds provide exceptional cone edge suspension and long-throw linearity with the proper amount of control and stability at excursion limits. Vented pole pieces provide additional cooling to the motor structure, resulting in an increase in the subwoofer’s thermal power handling capability.

Road noise can destroy realistic audio that always requires true low frequencies. Polypropylene delivers rigidity with good internal damping and complete weather-resistance. You get an impossible-to-miss increase in thumping bass.
A new, JBL-proprietary frame, unique inboard motor structure and new cone design create a woofer that is a full inch shallower than competing brands’ equivalent-sized models, expanding installation options. You can drive a compact car with sound that’s anything but compact.
Woofer motor structures heat up during use, causing distortion or power compression that reduces music’s dynamic range, robbing the sound of its realism. JBL® uses vented motor structures and polepieces that get rid of more heat to deliver more serious bang.
With 200 watts RMS and 800 watts of peak power handling and a frequency response of 30Hz to 400Hz, the GTO804 changes the experience of listening to your favorite music in your car. And a progressive spider gives better control for lower distortion at excursion limits.
