Our Verdict

Sonos Beam

LG SN9YG

The LG SN9YG is better than the Sonos Beam. The LG is a 5.1.2 setup with a dedicated subwoofer that helps reproduce a more extended low-bass. Unlike the Sonos, it supports Dolby Atmos content and has a Full HDMI In port. It also has a better surround performance and EQ presets for sound customization. That said, the 3.0 Sonos has better soundstage and center channel performances.
