Our Verdict

LG SN8YG

Samsung HW-Q800A

The Samsung HW-Q800A is a better 3.1.2 soundbar than the LG SN8YG. The Samsung is better built and gets louder with less compression at max volume. Its sound profile is more neutral out-of-the-box, which some users may prefer. It also has better soundstage and surround performances, and it comes with a graphic EQ. That said, the LG comes with a room correction feature.
