The Sub-Terranean series landscape subwoofers by James Loudspeaker provides the perfect solution to integrated outdoor audio. Rather than compromising the aesthetic of the landscape, these direct-burial subwoofers eliminate the need for an exposed bulky enclosure by hiding the main portion of the subwoofer underground. Using a bandpass box design, these water-tight, weather-proof speakers deliver deep powerful bass and a subdued visual effect, exposing only a small hooded port. These outdoor subwoofers come in a variety of sizes to suit the scale of any outdoor sound system and are available in both 4 ohm and 70V formats to accommodate any outdoor landscape application.
Each of these incredible subwoofers comes equipped with one of our proprietary aluminum cone woofers enclosed in a sealed aluminum enclosure with a heavy powder coat. The hooded port comes in our Standard Verde color with custom finishes options available for a small upcharge (ST15 and ST21 models come in Black standard finishes). 70V versions come with a heavy-duty, high-quality, low-distortion toroidal transformer ensuring all audio information is transferred to the subwoofer and high quality audio is achieved in any format. Upon request, a passive crossover can also be added to allow use with full range signal systems, and provide even greater versatility in system configuration. These subwoofers complete the James Loudspeaker landscape audio system package, delivering the high quality outdoor audio experience you’ve been looking for.
