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.
A JBL-proprietary frame, broad installation options
The proprietary die-cast frame design allows maximum cone excursion while reducing overall mounting depth. The die-cast structure maintains precise alignment tolerances over years of blasting music and rough roads. You get all the bass you’ve paid for.
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.
Outstanding audio output, low distortion
With 350 watts RMS and 1400 watts of peak power handling, the GTO1214 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.
Designed for sealed, vented, and bandpass enclosures
Different people have different opinions on what makes the best subwoofer box. Have it your way with the GTO1214, it can handle anything.
