Our Verdict
LG SN9YG
Sonos Beam (Gen 2)
The LG SN9YG is better than the Sonos Beam (Gen 2). The LG is a 5.1.2 setup with a dedicated subwoofer that can reproduce a more extended low-bass. It has less compression at max volume, and more sound enhancement features are available. However, the Sonos is still a solid choice for listeners who want a small, standalone setup. It's better built with better soundstage, center, and surround performances.
