Our Verdict
Sonos Arc
LG GX Soundbar
The Sonos Arc is better than the LG GX Soundbar. The Sonos is a 5.0.2 setup that's better built and offers better soundstage, center, surround, and Atmos performances. Unlike the LG, it has room correction and built-in voice assistant support. The 3.1 LG gets louder and has a Full HDMI In port that supports high-quality passthrough.
