Our Verdict
LG SN8YG
LG GX Soundbar
The LG SN8YG is a better soundbar for movies than the LG GX Soundbar. The SN8YG is a 3.1.2 setup that feels better built, it has a better performing center channel, and since it has up-firing speakers on the bar, its height performance is more immersive than the GX. The SN8YG has a room correction feature too. However, the GX is a 3.1 setup with a better balanced and neutral sound profile. The GX also has a better surround performance, even though it downmixes this content into stereo in order to play it. The GX can also get louder and there are less thumping and compression artifacts present at max volume.
