The GO12SW features a woofer with low-heat design is vented through the “chimney,” providing a constant flow of fresh air while always protecting the system from harsh weather and water. The flared chimney port system, combined with our polypropylene cone woofer with a high-intensity magnet structure, delivers deep, musical bass without chuffing or extraneous vibration. Bury the subwoofer nearby, or install it under your decking, and rock the very ground beneath your feet!
