Our Verdict

LG GX Soundbar

LG SP8YA

The LG SP8YA is a better soundbar than the LG GX Soundbar. The SP8YA is better-built with a more extended low-bass. It offers room correction and more wireless playback options. Unlike the GX, it doesn't have to downmix Atmos content to play it. However, the GX gets louder, and it has a better soundstage performance.
