About Polk Audio Atrium Sub100

Take your outdoor entertainment to the next level with the Atrium Sub100 Outdoor Subwoofer, featuring a robust 10" Woofer in a sleek gray finish. This high-performance subwoofer delivers powerful, indoor-quality bass in an all-weather, durable design, making it an ideal choice for your patio, poolside, or any transitional area in your home.

The Sub100 is more than just a subwoofer; it's the heart of your outdoor audio system, delivering the dynamic performance of a high-end audio system. Its 200-Watt downward-firing subwoofer delivers earth-shaking bass that will make your outdoor gatherings come alive with sound.

Designed for longevity, the Sub100 is housed in a molded and sealed acoustically ideal resin enclosure. It's marine-certified with an IPX66 rating, ensuring years of weather-proof outdoor performance.

The Sub100 is equipped with a massive 10-inch long-throw Dynamic Balance driver technology. This advanced feature eliminates driver distortion, providing deeper, cleaner bass even at higher volumes. The dual 2-inch voice coil design, coupled with Capacitive Coupling Technology, reproduces bass from both stereo channels, delivering more power in the lower frequencies for a big outdoor impact.

The Sub100 comes with a waterproof IP68 rated junction box for easy connection to other outdoor speakers, and it's approved for in-ground use. The included aluminum grille not only adds to its aesthetic appeal but also protects the woofer from the elements.

The Sub100's enclosure can be painted to match your landscape design. The color-impregnated resin will never fade, allowing it to naturally blend in with your outdoor setting. It's so versatile; you can even use it as a plant stand or pedestal table.

For added safety and security, the Sub100 includes a 1-meter Cl3 rated 4 conductor direct burial pigtail cable, eliminating the risk of exposed wiring. It also features an eye-bolt security anchor and screw-down points for added stability.

With built-in high-performance crossover technology, the dual-voice-coil Sub100 offers maximum wiring flexibility. It can be connected directly to its own amplifier channels for independent volume control. Experience the power and versatility of the Atrium Sub100 Outdoor Subwoofer and transform your outdoor space into a dynamic audio haven.
