12″ (300mm) Bandpass Subwoofer

A subwoofer designed to be seen and heard. Some car audio fans love the clarity of sealed subwoofer enclosures. Others crave the added power of vented enclosures. The GT-12BP bandpass
subwoofer offers both. It delivers accurate bass response and thundering power—as well as a bold look. The stylish box features a look-in acrylic window shaped like the JBL exclamation point, making the GT-12BP as appealing to the eyes as it is to the ears. And the sturdy enclosure shields the 12-inch polypropylene woofer from items that might shift in your trunk. The great value GT-12BP proves you don’t have to spend a fortune to enjoy legendary JBL bass.

Features and Benefits
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.
