The Polk Audio Atrium SUB100 is a heavy-duty, weather-resistant outdoor passive subwoofer designed for year-round use in patios and gardens.

The subwoofer's IP66-rated junction box supports in-ground installation, and its paintable finish allows it to blend seamlessly with landscape design. An included aluminum grille protects the driver, while the robust cabinet can double as a plant stand or pedestal table.
