About the Atrium Sub100
The Polk Audio Atrium Sub100 delivers powerful, indoor-level bass performance outdoors with its marine-certified, weatherproof design (IP66/IPX66 rating). Featuring a 10-inch Dynamic Balance composite cone driver with dual 2-inch voice coils and butyl rubber surround, it uses capacitive coupling technology to reproduce bass from both stereo channels for enhanced low-frequency impact. The sealed acoustic suspension enclosure withstands seasonal elements, includes a waterproof IP68 junction box for easy connections, aluminum grille, eye-bolt security anchor, and 4-conductor direct burial pigtail cable. Paintable to blend with decor, it complements Atrium Sat300 satellites perfectly. Built-in low-pass crossover at 150 Hz allows direct amplifier connection with independent volume control. Ideal for patios, walkways, pools, and parks.
