Product Features
Big bass with Polypropylene woofer cone
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.
Outstanding audio output, low distortion
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.
Exceptional venting for increased power handling
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.
Enclosure up to JBL Professional standards
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.
Accurate frequency response
With a frequency response of 23Hz – 450Hz, the GT5-12 reproduces deep, teeth-rattling bass tones without distortion.
