Description
12” In-Ground Subwoofer
The JBL GSB12 in-ground 12-inch landscape subwoofer augments the low-frequency performance of JBL GSF full-range landscape speakers to provide rich, full-range sound in lawn and garden areas of hospitality, corporate and retail spaces. The GSB12 focuses on fidelity, with true subwoofer extension down to 30 Hz and a steep, multiple-slope lowpass filter for superior sound. Its premium-grade, 200-watt subwoofer-band transformer allows use in 70V/100V systems or can be connected for low-impedance direct operation. This sleek, ultra-low-profile speaker—winner of international design awards for industrial design excellence—installs underground, with only the audio port visible. It’s designed to withstand the elements: Its chamber is oriented directly below the audio port to prevent accidental damage from landscaping, which can be a problem with side-located chambers. Grab handles allow easy installation and tabs secure the subwoofer to blocks or anchors.
