Overview
Wireless and floor-standing, the Polk Audio REACT-SUBWOOFER pairs a 7-inch driver with 25 watts of power, built as a companion sub for Polk's React soundbar line.
Its wireless link means placement isn't tied to a cable run back to the amp, and at 8.6 x 13.7 x 16.5 inches it's sized for a floor spot in a corner or beside furniture rather than a shelf.
- 7-inch driver
- 25 watts rated power
- Wireless connectivity
- Floor-standing black enclosure
Who it's for
Suits owners of a Polk React soundbar looking to add bass without running a wire across the room. Not intended as a standalone sub for a separate amplifier setup, since the wireless pairing is built around Polk's own ecosystem.
Pros and cons
- Wireless connection, no cable run to the soundbar
- Floor-standing design fits corner placement
- 25W power is modest next to standalone subwoofers
- Pairing appears built around Polk's own React ecosystem
Performance notes
With a 7-inch driver and 25 watts of power, it's built to add low-end fill for a soundbar system rather than compete with larger standalone subs, and its floor-standing design keeps the wireless receiver and driver in one enclosure.
