Our Verdict
Vizio M Series M512a-H6
Samsung HW-Q930B
The Samsung HW-Q930B is better than the Vizio M Series M512a-H6. The Samsung is a more premium Dolby Atmos soundbar and better built overall. Its surround and Atmos performances are better, so sound effects are more accurate in the mix, and it also comes with more sound enhancement features. However, the Vizio is a good option if you're looking for an immersive sound at a more affordable price. It even has a better soundstage than the Samsung soundbar.
