The ST8-4 is the second in our line of mini landscape subwoofers designed for local zone bass performance. It can be configured with 1 satellite speaker as a mono channel, 2 satellite speakers as a 2.1 stereo or with multiple satellite speakers in small patio areas. James’ subterranean subwoofer’s direct burial, 8” compression band pass design creates unrivaled low end frequency response. An external hooded port, aircraft/marine grade aluminum enclosure, and stainless steel hardware provide increased protection in extreme weather conditions.
