Vizio M-Series 5.1.2 Channel Sound Bar with Dolby Atmos (M512a-H6) review

Lewis Leong

The Vizio M512a-H6 is the company’s follow up to the excellent M51a-H6 with the main difference being the addition of two up-firing Dolby Atmos speakers. For the uninitiated, Dolby Atmos offers spatial audio that is more immersive by adding up-firing speakers to help aid soundstage height. More and more streaming services are adding movies mixed for Dolby Atmos to take advantage of this new audio format. 

The M512a-H6’s name hints at how the system is setup. There are five channels with one subwoofer, and an additional two up-firing Atmos speakers. The sound bar itself contains a center, left, right channels as well as the aforementioned two up-firing Atmos speakers. The subwoofer connects wireless with the sound bar but the two satellite speakers are wired and need to be plugged into the subwoofer.  

All that said, sound quality is good, and the addition of the two Atmos speakers help create a more immersive movie watching experience. While not the most detailed nor the most full featured soundbar system, at just $450 (about £325 / AU$582)*, the Vizio M512a-H6 is an excellent value for an entry-level surround soundbar system.
