Polk Audio Atrium Sub100 Outdoor Subwoofer
Description
The Polk Audio Atrium Sub100 is a premium outdoor passive subwoofer engineered to bring deep, powerful bass to gardens, patios, poolside entertainment areas, and outdoor living spaces. Designed specifically to complement Polk's Atrium outdoor speaker range, the Sub100 delivers impactful low-frequency performance that transforms outdoor music and entertainment experiences. Its innovative landscape-friendly design allows it to blend naturally into outdoor environments while providing the rich bass response typically associated with indoor audio systems.
At the heart of the Atrium Sub100 is a 10-inch long-throw Dynamic Balance® driver with dual voice coils, housed within a rugged all-weather enclosure. The downward-firing design ensures smooth and even bass dispersion, while Polk's Capacitive Coupling Technology enhances low-frequency output for greater impact and depth. Built to withstand harsh outdoor conditions, the IPX66-rated enclosure, aluminum grille, and weatherproof construction provide years of reliable performance in any climate. The Sub100 is acoustically matched with the Atrium Sat300 speakers, making it the perfect foundation for a premium outdoor audio system.
