Our Verdict

Vizio V Series V51-H6

Samsung HW-A650

The Vizio V Series V51-H6 is better than the Samsung HW-A650. The Vizio is a 5.1 setup that reproduces a more extended low-bass. It also gets louder with less compression at max volume, and it has a better surround performance. However, the 3.1 Samsung is better built with a graphic EQ for sound customization.
