JBL GSF3-TN Landscape Speaker with Ground Spike (2-Pack)

JBL Professional GSF3-TN - Landscape Speaker with Spike (2-Pack), 3" Coaxial, IP66, 70/100 V, 8 Ω

The JBL Professional GSF3-TN is a compact, weatherproof landscape speaker designed to deliver superior fidelity and even coverage in outdoor commercial applications. Its 3" 2-way coaxial system combines a 25 mm polypropylene voice coil woofer and a 20 mm titanium dome tweeter with neodymium magnet, achieving clear and balanced sound. It incorporates a 15 W multi-tap transformer for 70/100 V distributed lines and can be switched to 8 Ω for low-impedance operation, facilitating integration into new or existing systems.

Its polycarbonate + ABS (UL94V-0) housing and aluminum grille achieve an IP66 rating against dust and powerful water jets, and pass stringent environmental tests ( salt spray , humidity, temperature, and UV). The adjustable hinged mount allows for precise beam steering, and the GSF3-TN includes a ground spike for in-ground installation and an L-bracket for surface mounting. A drain hole in the base prevents water buildup, and the tap selector is located at the bottom, protected from rain. For extended bass, it can be combined with the JBL GSB8 or GSB12 in-ground landscape subwoofers.
