Most LG Sound Bars come paired with a wireless subwoofer. The subwoofer should pair automatically with its corresponding sound bar when powered on. If the subwoofer does not pair automatically, this can be resolved with a few troubleshooting steps.
For best performance, ensure the subwoofer is within 15 ft. of the sound bar.
The sound bar and subwoofer are designed to work together as a complete system. Using a different subwoofer may result in compatibility issues.

LED Indicator Colors:
Blinking Green: Connecting in progress
