JBL Professional JBL-GSB8-GN 8" In-Ground Subwoofer, Green

Bring dependable, room-filling low end to outdoor environments with the JBL Professional GSB8 8" In-Ground Subwoofer. Designed for landscape audio and commercial sound reinforcement, this pro subwoofer extends clean, controlled bass down to 35 Hz using a 209 mm (8") polypropylene driver and a steep built-in low-pass filter—so music, announcements and security paging deliver impact without boominess. The GSB8 supports low-impedance direct connection or can be integrated into 70V/100V systems with its premium-grade subwoofer-band transformer, giving AV integrators flexibility across hospitality, retail and municipal applications.

Built for the elements, the in-ground enclosure places the tuned chamber below the audio port to resist landscaping damage, while weather-resistant construction stands up to moisture, salt, UV and temperature extremes. Its ultra-low profile leaves only the audio port visible for a discreet aesthetic in gardens, promenades and theme parks. The GSB8 also integrates well with site-wide security and surveillance paging systems, providing intelligible, powerful bass for emergency notifications and public address.
