Our Verdict

LG SP8YA

Vizio M Series M512a-H6

The Vizio M Series M512a-H6 and LG SP8YA are similarly performing bars, despite having different setups. The Vizio is a 5.1.2 setup with discrete satellite speakers offering a better surround performance. It also has a better stereo soundstage. That said, the 3.1.2 LG has more wireless playback options and a room correction feature.
