Our Verdict
LG GX Soundbar
LG SP9YA
The 5.1.2 LG SP9YA is better than the 3.1 LG GX Soundbar. The SP9YA is better built, and it can reproduce a more extended low bass. It offers better center and Atmos performances. Also, there are more wireless playback options and sound enhancement features, including room correction. That said, some users may prefer the GX's unique design.
