Our Verdict
Vizio M Series M51ax-J6
Samsung HW-Q67CB
The Vizio M Series M51ax-J6 is a 5.1 Dolby Atmos soundbar just like the Samsung HW-Q67CB. They're similar, but the Vizio is better overall. It reproduces more bass, so you feel more thump and rumble in music and movies. There's less compression as you crank up the volume, too. It doesn't have a graphic EQ like the Samsung, but there are still bass and treble adjustments to give you some control over its sound.
