Our Verdict
Vizio M Series M51a-H6
Samsung HW-A650
The Vizio M Series M51a-H6 is better than the Samsung HW-A650. The Vizio is a 5.1 setup that supports Dolby Atmos content and comes with discrete satellites, unlike the Samsung soundbar. It also reproduces a more extended low bass and has a better surround performance. However, the 3.1 Samsung is better built, and some users may prefer its graphic EQ for sound customization.
