Features
Injection-molded polypropylene cone
The polypropylene woofer cone in the GT-12BP is engineered for superior rigidity, reliability and sensitivity. The result is increased low-frequency output and powerful, natural-sounding bass.
Slot vent
The GT-12BP’s enclosure is vented, which enables the subwoofer to deliver ultra-low bass at higher sound pressure levels than a sealed enclosure.
Acrylic window
Some subwoofers are meant to be seen as well as heard. The GT-12BP features an acrylic window shaped like the JBL exclamation point and orange illumination, so you can look into the enclosure and see what legendary bass looks like.
Durable construction
The GT-12BP bandpass enclosure doesn’t just produce signature JBL bass performance, it protects it. The rigid box keeps the woofer safe from anything that might slide around in your trunk.
