About the React Sub
The Polk Audio React Sub is a compact wireless powered subwoofer designed specifically to pair with the Polk React sound bar (and compatible React surround system configurations). It uses a 7-inch long-throw, high-excursion woofer in a bass-reflex enclosure with a flared port to extend low-frequency response. It connects wirelessly to the compatible React sound bar, allowing placement up to approximately 30 ft (10 m) from the bar, while requiring AC mains power at the subwoofer location. Polk specifies bass response down to 24 Hz; a separately published system-frequency figure is 20–150 Hz. The official product page remains listed, including an outlet listing, so it is not treated as no longer manufactured; availability may vary by region.
