Get to know this product.

The 101ST70 is one of several options in our line of landscape subwoofers designed for local zone bass performance. Intended for small to medium sized areas, it can be configured with any array of satellite speakers in a mono system, a 2.1 stereo system, or any combination of satellite configurations in a variety of outdoor areas.

Having mastered the mix of excellence in design, technology, and superior sound, outdoor entertainment has never been so complete. Designed with motion in mind, James Loudspeakers outdoor systems provide consistent sound levels in multiple stereo listening areas: by the pool, next to guests mingling at the barbecue, or at the surrounding tennis courts.

James subterranean subwoofer’s direct burial, 10” compression band pass design creates unrivaled low end frequency response, while the external hooded port, aircraft/marine grade aluminum enclosure, aluminum woofer, and stainless steel hardware provide superior protection in extreme weather.

All James subterranean subwoofers are designed to be buried underground leaving only the hooded port visible. With a standard verde finish as well as the availability of custom color options with an additional charge, these subwoofers are able to be completely camouflaged into the environment, leaving as little visual impact as possible.

James 70 volt speakers are equipped with an all-copper toroidal transformer, designed to eliminate distortion and frequency loss, providing high quality, crystal clear, full range audio.

This 10” subwoofer uses a 100 Watt transformer delivering powerful bass with high clarity
