JBL Professional JBL-GSB12-GN 12" In-Ground Outdoor Landscape Subwoofer, Green

Bring powerful, professional bass to outdoor environments with the JBL Professional GSB12 12-inch in-ground landscape subwoofer. Designed for hospitality, retail, corporate and public spaces, the GSB12 extends low-frequency response down to 30 Hz and handles 450W continuous power, delivering the deep, authoritative low end that completes full-range landscape speaker systems. The passive 12" driver and built-in multiple-slope lowpass filter provide tight, accurate bass that translates to better music, paging and ambient sound without muddying midrange clarity.

Installers benefit from a weather-resistant, ultra-low-profile in-ground enclosure with a chamber oriented beneath the audio port to avoid landscaping damage, plus grab handles and anchor points for fast, secure mounting. The premium subwoofer-band transformer supports 70V/100V networks or low-impedance direct connection, making the GSB12 simple to integrate with outdoor PA, security audio and monitoring systems. Compatible with JBL GSF full-range landscape speakers, it helps create cohesive audio zones across lawns, plazas and walkways.

For durable, high-performance outdoor bass—ideal for hotels, shopping centers, theme parks and public venues—add the JBL GSB12 to your next installation. Contact sales or order now to upgrade your landscape audio.
