SoundTube XT850-SUB-GN 8" Outdoor In‑Ground Subwoofer with SuperT Low‑Loss Transformer, Green

For outdoor venues and security-conscious installations that need authoritative low end, the SoundTube XT850-SUB is a purpose-built pro subwoofer that delivers consistent, high-impact bass where it matters most. This in-ground subwoofer uses a sealed enclosure and an 8" polypropylene cone to produce true low-frequency response without a large surface footprint, ideal for landscaped areas, plazas, and perimeter audio systems. The integrated SuperT low-loss transformer provides clean power transfer for 25/70.7/100V distributed systems while a transformer-bypass lets you run a direct 8 Ω connection for maximum output. Built to withstand the elements, the XT850-SUB carries an IP55 rating and features UV-, scratch- and chlorine-resistant construction plus a powder-coated stainless steel grille and anti-theft mounting hardware for secure, long-term outdoor use. Use it to reinforce background music, public-address announcements, or to add bass presence to security and surveillance audio zones.
