Our Verdict
LG SN9YG
LG GX Soundbar
The LG SN9YG is better than the LG GX Soundbar. The SN9YG is a 5.1.2 setup that's better-built with better center, surround, and Atmos performances. It reproduces a more extended low-bass, and it comes with room correction. It also has built-in voice assistant support. That said, the 3.1 GX Soundbar has a better stereo soundstage.
