Description
JBL JBL-GSB8-GN 8" In-Ground Subwoofer, Green
The JBL-GSB8-GN is a purpose-built in-ground subwoofer engineered for permanent outdoor installations where weather resistance and consistent low-frequency performance are non-negotiable. Its compact footprint and integrated grab handles make deployment straightforward, while the robust construction delivers reliable bass reinforcement in fixed landscape and architectural audio applications.
Design & Durability
Built to withstand outdoor exposure, this subwoofer carries an IP66 weather rating and measures 768 mm height × 311 mm diameter (30.1 × 12.2 inches), fitting flush into ground installations without protruding visual clutter. Integrated grab handles and anchor points simplify both installation and future maintenance in field conditions.
Audio Performance
The 8-inch polypropylene woofer with 38 mm (1.5") voice coil on Kapton former delivers low-frequency extension down to 35 Hz, providing the depth needed for outdoor events and venue reinforcement. The built-in steep, multiple-slope lowpass filter integrates cleanly with line-level feeds from your console or processor. A 100W subwoofer-band transformer offers flexible operation in 6-ohm direct mode or 70V/100V multitap configurations—essential for distributed audio systems where you need synchronized bass across multiple zones.
