The Vizio M Series M512a-H6 is a 5.1.2 setup released in 2021. It's a mid-range offering from the manufacturer that's one of the few bars in its price range to include rear satellites for a more immersive surround sound. As with many Vizio bars, you have to wire the satellites to the sub, which isn't ideal for every living room setup. Without up-firing drivers on its satellites, it doesn't sound quite as immersive as the more premium Vizio Elevate.
Note: We bought and tested another unit in compliance with our out-of-spec policy. We've tested the new unit and have updated the review accordingly.
Our Verdict
The Vizio M512a-H6 is very good for mixed usage. It's a versatile 5.1.2 bar that stands out from other bars at its wallet-friendly price point. Plug it into your TV, and voices and lead instruments are clear right out of the box, thanks to its balanced sound. The sub brings rumble in the bass to bring bass-heavy genres and action-packed scenes to life, and its satellites can add to the immersive feeling of movies, although they produce a lot of distortion at high volumes. Compared to more premium offerings, it doesn't bring the same cinematic feeling, especially with Atmos content, but if you're on a tighter budget, it's a solid pick.

- Gets loud.
- Clear vocal reproduction.
- No graphic EQ.
The Vizio M512a-H6 is great for vocal-centric TV shows and podcasts. It's a 5.1.2 setup, so there's a discrete center channel to improve vocal reproduction. With its balanced mids, dialogue is clear and detailed, and you don't have trouble following the action on screen. If you want voices to sound even more clear and crisp, there's a dialogue enhancement feature on hand. You can easily stream podcasts from your mobile devices over Bluetooth, though unfortunately, you can't do so over Wi-Fi, AirPlay, or Chromecast.

- Dialogue enhancement feature.
- Bluetooth-enabled.
- No graphic EQ.
The Vizio M512a-H6 is very good for music. Its sound profile is fairly balanced out of the box, especially in the mids, where most voices and lead instruments reproduce. Thanks to its dedicated subwoofer, you get plenty of rumble in the bass. As a result, it's suitable for most music genres. A few customization tools are on hand to switch up its sound, including bass and treble adjustments. Unfortunately, you don't get a full graphic EQ to customize across the range.

- Gets loud.
- No graphic EQ.
The Vizio M512a-H6 is good for movies. Especially compared to other bars at its price point, it performs well. You can watch common surround sound formats like Dolby Digital as well as object-based formats like Dolby Atmos, which are found on most streaming services. Its satellites offer a fairly immersive listening experience, too, so sound effects seem to come from all around you as if you're right in the middle of your favorite movie. However, it doesn't reproduce the same feeling of height as more premium setups, and the surround performance is uneven, resulting in a bit less of a dimensional sound.
- Gets loud.
- Supports Dolby Atmos.
- No graphic EQ.

Popular Soundbar Comparisons
The Vizio M512a-H6 is a mid-range 5.1.2 soundbar with satellites and a subwoofer included. It's pretty versatile, especially compared to other bars at its price point, like the LG SP8YA. You won't find as many customization tools as with more premium bars, and there's not as much of a cinematic feel with Atmos content. Still, if you don't want to spend a lot on a bar, it's a solid value pick.
