With a focus on fidelity and a sleek, award-winning, ultralow-profile design, the tan GSB12 In-Ground Subwoofer from JBL is the perfect complement to the GSF full-range landscape speakers, providing a powerful 12" polypropylene driver that can be mounted underground but still provides potent subwoofer performance down to 30 Hz. This subwoofer can handle up to 1800W peak power input from its bare-wire input, and with an IP66 weather rating and a chamber oriented directly below the audio port, this subwoofer is completely safe for long-term outdoor use in a range of applications, including hotels, parks, retail spaces, event spaces, and more.

The steep, built-in low-pass filter sports multiple slopes for quality sound reproduction. The GSB12 also includes a 200W subwoofer-band transformer with either direct, 6-ohm operation or multitap functionality for installed systems, supporting 70 and 100V modes. Grab handles make it quick and simple to install and anchor points are included for securing the cabinet to blocks or anchors. The GSB12 includes seven gel-filled wire nuts for aiding in connection to audio systems.
