JBL Professional JBL-GSB8-TN 8" In-Ground Subwoofer, Tan

Bring impactful, professional bass to outdoor landscapes and public spaces with the JBL Professional GSB8 in-ground subwoofer. Designed for hospitality, retail, parks and corporate campuses, this pro subwoofer adds low-frequency depth to JBL GSF full-range landscape speakers so music, paging and ambient audio feel full and natural even across lawns and plazas. The GSB8’s 8" woofer and 150W RMS power produce reliable bass down to 43 Hz (response to 120 Hz), while an 84 dB sensitivity and 6 Ω impedance ensure efficient, predictable performance with common amplifiers. Built to last outdoors, the IP66-rated, weather‑resistant enclosure stands up to moisture, salt air and UV exposure for minimal upkeep and long service life. For integrators and AV/security teams, the discreet in‑ground form factor provides hidden bass reinforcement that complements surveillance, security paging and monitoring systems without visual clutter. Specify the JBL GSB8 when you need durable, high‑quality outdoor low end—ideal for landscape audio installations and venue-wide sound reinforcement. Contact your JBL Professional dealer to configure and deploy.
