Features
Overview: The Polk Atrium Sub100 delivers heavy-duty bass performance and all-weather durability with indoor level bass performance. Designed for outdoor use, the Sub100 passive subwoofer features a 10" downward firing subwoofer in a weatherproof sealed enclosure that's ideal for patios, walkways, pool areas, parks, and other outdoor venues. The Atrium Sub100 is a perfect match for the Polk Atrium Sat300 satellite speakers for a 3-way system.
Driver: The Sub100 features a 10" long-throw Dynamic Balance driver for deeper, cleaner bass while eliminating driver distortion. It's dual 2" voice-coils (8Ω each) include separate wire inputs for each, allowing the sub to be driven from a stereo amplifier (sold separately). The downward-firing sub can handle up to 200 watts of power and is protected by a weather-proof aluminum grill.
Enclosure: The 10" subwoofer driver is housed in a molded and sealed resin enclosure that's acoustically optimized and carries an IPX66 weather-proof rating, giving it year-round outdoor performance. The color-impregnated resin housing will never fade and is designed to naturally blend with the outdoor environment. It can be painted to match the surroundings and can even be used as a plant stand or pedestal table. The underside of the Sub100 features 4 screw-down keyhole slots and an eye-bolt security anchor for added stability and security.
Crossover: The Sub100 includes a built-in high performance low-pass crossover at 150 Hz, allowing the sub to be powered from a full-range amplifier (sold separately).
Junction Box: Included with the Sub100 is a waterproof junction box for connecting other outdoor speakers along with the subwoofer. The junction box has an IP68 waterproof rating and is approved for in-ground use.
Wiring: Connection to the subwoofer is done through a 39" 4-conductor set of wires that's rated for direct burial. Four waterproof wire-nuts are included for in-ground connections. The sub's bare ended wires are color coded and labeled:
