The Rockustics OneSub is a rugged, weather-resistant outdoor subwoofer designed to deliver deep, powerful bass in any environment. Built with a durable rock enclosure, it withstands rain, frost, snow, and ice, making it ideal for residential and commercial outdoor spaces. The OneSub is a stand-alone, passive subwoofer requiring a sub amplifier with an active crossover. For larger systems, pair it with DubSub subwoofers to create a Sub/Sat configuration—simply wire two additional full-range speakers to the DubSub for a three-speaker system powered by any traditional amplifier without the need for a sub amp or external crossover.
