How to Connect a Wireless Subwoofer to a Vizio Sound Bar

The Sound Bar from Vizio is a compact speaker unit that can be mounted to a wall or placed on a TV stand. It can be purchased with or without a compatible wireless subwoofer. The method you use to connect a wireless subwoofer to the Sound Bar depends on the Sound Bar you purchased. If you purchased a Sound Bar that comes with a Vizio wireless subwoofer, link the devices by pressing the appropriate buttons. If you purchased a Sound Bar that doesn't come with a wireless subwoofer, connect a wireless subwoofer by connecting its transmitter to the Sound Bar.
