JBL GSB12-GN 12" Landscape In-Ground Garden 70v Commercial Subwoofer Outdoor Sub

The JBL GSB12 is a 12-inch in-ground landscape subwoofer in hunter green that adds the low end JBL GSF full-range landscape speakers cannot produce on their own. Outdoor audio without a subwoofer tends to sound thin, especially across open lawn where there are no surfaces to reinforce bass. The GSB12 fixes that with true extension down to 30 Hz.

The cabinet buries in the ground with only the audio port visible above the surface. Its chamber sits directly below that port rather than off to one side, which keeps the buried volume out of the path of shovels, edgers and aeration equipment. Grab handles make the drop-in easier and anchor tabs secure the cabinet to blocks or ground anchors.

A built-in steep, multiple-slope lowpass filter keeps the subwoofer in its own range without outboard processing. A premium 200W subwoofer-band transformer serves 70V and 100V distributed lines with taps at 200W, 100W and 50W, and the driver connects directly for low-impedance operation. Power handling is 450W continuous pink noise with 1,800W peak and 118 dB peak SPL.

The 305 mm polypropylene driver rides on a 50 mm voice coil, and the LDPE polyethylene enclosure is colored throughout with a 6 mm minimum wall thickness. It suits hotels, shopping complexes, restaurants, theme parks and corporate campuses. Net weight is 35.7 lb.
