Our Verdict

LG SN11RG

Sonos Arc

The LG SN11RG is a better overall soundbar compared to the Sonos Arc as a standalone bar. The LG has a subwoofer plus satellites to help its sound, but you can purchase these speakers separately for the Sonos Arc. The LG can also reproduce more bass, and while it can't get as loud as the Sonos, it can reach its max volume with fewer compression artifacts. It also has more sound enhancement features and connectivity options like two Full HDMI In ports. It even supports Bluetooth for a wireless connection. That said, on its own, the Sonos has a better height performance. Unlike the LG, you can also use it with Apple AirPlay.
