Soundtube XT850-SUB-GN 8in Outdoor Subwoofer / Sealed In-Ground / IP55 Weatherproof / 80W RMS / 25/70.7/100V

Description

The XT850-SUB is an 8in outdoor subwoofer engineered to reproduce low frequencies for outdoor installations. It uses a sealed in-ground enclosure design to deliver controlled low-end response and consistent on-axis performance. The enclosure and components are treated for UV, chlorine, scratch, and weather resistance to ensure long-term outdoor durability.

Key features include an 8in polypropylene cone woofer with butyl rubber surround, an integrated SuperT transformer for low-frequency handling, and a weatherproof 2-position tap switch for 25/70.7/100V operation plus transformer bypass. The speaker is IP55 rated and includes theft-resistant mounting hardware and a powder-coated stainless steel grille. These features provide reliable SPL and low-frequency extension in exposed environments.

Technically the XT850-SUB offers a frequency response of 30 Hz – 150 Hz (±10 dB) and 46 Hz – 150 Hz (±3 dB), 80 W continuous RMS power handling and 160 W program power. Nominal impedance is 8 Ohm and sensitivity is 86 dB at 1W/1M, allowing integration with a variety of amplifiers. The sealed design helps maintain consistent low-frequency performance while protecting internal components from moisture and contaminants.

Connectivity is delivered via wire leads and a weatherproof tap switch that supports 25 / 70.7 / 100 V distributed systems or direct 8 Ohm operation when the transformer is bypassed. The included anti-theft bracket and weatherproof strain relief simplify secure and durable cable termination. The grille and enclosure materials are selected for long outdoor service life and minimal maintenance.

Typical applications include landscape audio systems, resort and poolside installations, theme parks, and municipal outdoor areas where robust low-frequency reproduction is required. The subwoofer excels where a concealed in-ground installation is preferred while maintaining serviceable access for wiring and secure mounting. Its performance profile supports both music playback and reinforcement of outdoor paging and ambiance systems.

Installation is straightforward for experienced AV technicians – the unit ships with anti-theft mounting hardware, wire nuts, and a weatherproof strain relief to aid secure terminations. The construction emphasizes corrosion-resistant finishes and a powder-coated stainless steel grille to limit visible wear over time. Overall the XT850-SUB provides a durable, weatherproof subwoofer solution that balances low-end output, transformer flexibility, and long-term outdoor reliability.
