SoundTube Rockustics OneSub Series Outdoor Subwoofer

The SoundTube Rockustics OneSub Series is a high-performance outdoor subwoofer solution, purpose-built for landscape audio systems that demand deep, powerful bass in a weather-resistant form factor. Designed to resemble natural stone, the OneSub blends seamlessly into gardens, patios, or commercial outdoor environments. With a single 8-Inch driver and passive design, it’s ideal for systems using external subwoofer amplifiers and active crossovers.

Crafted from durable, weather-resistant materials, the OneSub can withstand rain, frost, snow, and ice without compromising performance. Its wide low-frequency response down to 32 Hz adds richness and presence to any outdoor music system. Whether you’re designing an immersive landscape theater or upgrading a commercial patio zone, the OneSub delivers exceptional low-end clarity in a rugged, camouflaged enclosure.

For integrators and homeowners seeking premium outdoor audio with subtle aesthetics and reliable performance, the Rockustics OneSub series stands out as a top-tier solution. Pair it with compatible full-range landscape speakers and a dedicated subwoofer amplifier for best results.
