Our Verdict

LG GX Soundbar

Samsung HW-Q950A

The Samsung HW-Q950A is better than the LG GX Soundbar. The Samsung is a better built 11.1.4 setup with dedicated satellites. It has better center, surround, and Atmos performances. It also offers more sound enhancement features, like room correction, and more wireless playback options. Unlike the LG, it has built-in voice assistant support. Also, it can reproduce a more extended low-bass.
