JBL Professional 12" in-ground subwoofer, tan, 1 pc
The JBL GSB12 in-ground 12-inch landscape subwoofer is engineered to deliver powerful, deep bass performance for outdoor sound systems in commercial and hospitality environments. Designed as the perfect companion to JBL GSF full-range landscape speakers, the GSB12 enhances low-frequency output, ensuring a rich, full-range listening experience across large outdoor spaces such as hotels, restaurants, retail complexes, resorts, and theme parks.
Built for premium fidelity, the GSB12 provides true subwoofer performance with extension down to 30 Hz. Its steep, multiple-slope lowpass filter guarantees smooth integration with full-range systems, while the high-quality 200-watt transformer supports both 70V/100V distributed audio systems and low-impedance direct operation. This versatility makes it a flexible solution for a wide variety of professional installations.
The GSB12 is also designed with durability and installation efficiency in mind. Its award-winning industrial design places the chamber directly below the audio port, preventing accidental landscaping damage common with side-chamber enclosures. Grab handles make placement and positioning straightforward, while built-in anchor points ensure secure installation. Available in hunter green or tan, the subwoofer blends seamlessly into any outdoor environment.
Whether installed in corporate courtyards, public parks, or entertainment venues, the GSB12 delivers legendary JBL audio quality with the deep, reliable bass performance required for immersive outdoor soundscapes. With rugged materials, weather resistance, and discreet visual integration, the GSB12 is a professional-grade solution for enhancing outdoor audio systems.
