GSB12 Green [Open Box]

The JBL GSB12 is a 12-inch in-ground landscape subwoofer built to add real low end to lawn and garden sound systems at hotels, restaurants, shopping complexes, and theme parks. It extends bass response down to 30 Hz using a steep, multiple-slope lowpass filter, and a premium 200-watt subwoofer-band transformer supports 70V or 100V distributed systems as well as low-impedance direct operation.

The cabinet installs entirely underground, leaving only the audio port visible above the lawn, and its internal chamber sits directly below that opening rather than to the side, reducing the risk of damage from landscaping equipment. Grab handles make the subwoofer easier to lower into place, and anchor tabs secure it to blocks or ground anchors so it stays put through mowing and yard work.

Handling up to 900W continuous program power at up to 118 dB peak, the GSB12 pairs naturally with JBL GSF full-range landscape speakers to round out an outdoor sound system. It ships in a hunter green finish that blends into most garden and lawn settings.
