Put your Klipsch subwoofer anywhere you want with the WA-2 wireless subwoofer kit. This simple, two-piece plug-and-play kit adds wireless audio capability to select Klipsch subwoofers in seconds. Plug your sub into a nearby wall outlet, connect the small wireless receiver to the proprietary "WA Port" on the back of the sub, connect the transmitter to your receiver and power, and you're done. The transmitter sends wireless audio signals from your receiver to the sub, so you won't have to worry about running interconnect cables across your floor.
