Description
JBL JBL-GSB12-GN 12" In-Ground Subwoofer
The JBL-GSB12-GN is a purpose-built landscape subwoofer engineered to disappear into outdoor installations while delivering serious low-frequency performance. Its ultra-low-profile design installs flush with or below ground level, leaving only the audio port visible—making it ideal for permanent installations where aesthetics matter alongside sonic capability.
Installation & Design
This subwoofer's revolutionary form factor requires minimal excavation and integrates seamlessly into hardscape or lawn environments. The IP-66 weather rating ensures dust and water resistance, while the durable polypropylene injection cone with thermoplastic vulcanizate surround resists UV degradation and moisture ingress over years of outdoor exposure.
Audio Performance
The 305mm (12") polypropylene driver with a 50mm voice coil delivers authoritative low-end reach down to 30 Hz, while the 200-watt transformer supports both 70V/100V distributed systems and low-impedance direct operation. Peak output reaches 118 dB with continuous ratings of 111 dB (2 hrs), ensuring this subwoofer keeps pace with serious outdoor sound systems.
