For anyone who likes to crank it up in the car, the new JBL® 305mm (12 inch) 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.
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.
With 250 watts RMS and 1100 watts of peak power handling, the GT5-12 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.
Woofer motor structures heat up during use, causing distortion, or power compression that reduces music’s dynamic range, robbing the sound of realism. JBL uses vented motor structures and polepieces that get rid of more heat to deliver more serious bang.
It’s built to the same exacting standards as JBL professional audio boxes with 3/4" medium-density fiberboard construction, and high-quality binding-post terminals. Wide-bandwidth design provides more output between 20Hz and 40Hz. You get all the bass you’ve paid for.
With a frequency response of 23Hz – 450Hz, the GT5-12 reproduces deep, teeth-rattling bass tones without distortion.
