All-Weather Subterranean Subwoofers

Outdoor Living subwoofer enclosures disappear just below the surface of the ground, with only its unobtrusive “mushroom cap” port visible. The enclosure is constructed of high-density polyethylene, the same material that ensures a long life for underground water systems. This enclosure can withstand flooding rains and wild temperature extremes, and has been successfully tested underwater and in environments from -20°F to 185°F.
The woofer’s low-heat design is vented through the “mushroom cap,” providing a constant flow of fresh air while always protecting the system from harsh weather and water. The flared port system, combined with our polypropylene cone woofer and a high-intensity magnet structure, adds deep, musical bass to the whole area with no chuffing or extraneous vibration. Bury the subwoofer nearby, or install it under your decking, and add a surprisingly vibrant low end to your outdoor entertainment.
