Our Verdict

Vizio M Series M213ad-K8

Vizio M Series M215aw-K6

The Vizio M Series M215aw-K6 is better than the Vizio M Series M213ad-K8. They're both 2.1 setups that support many different audio formats, including Dolby Atmos. However, the M213ad-K8 is a standalone bar. It's a better choice if you're low on space, but the M215aw-K6's added subwoofer makes a big difference in the sound quality, so you feel more rumble in action-packed movies and bass-heavy music genres. If you can find space for the sub, it's the better choice overall.
