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. However, the two up-firing drivers in the bar make a real difference with Dolby Atmos content, especially compared to budget selections like the Vizio M Series M51a-H6.
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 great for mixed usage. It's a versatile 5.1.2 bar that stands out compared to 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 add to the immersive feeling with movies. 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.

There are a few customization tools 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.

The Vizio M512a-H6 is great 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, which reduces its overall cinematic feel.

Test Results
The Vizio M512a-H6 has a simple design. It's mostly made of plastic draped with fabric. In the middle of the bar, there's a metal grille protecting the two up-firing speakers.
The sub is mostly made of melamine, and the top is made of plastic. It sits on four plastic pegs with rubber grips.
The satellites are mostly made of plastic. There's fabric covering the front and the sides. They need to be wired to the sub to work. If you don't have space in your setup for satellite speakers, you may prefer a different Atmos setup like the Polk Audio Signa S4.
Due to its width, the Vizio M512a-H6 doesn't fit between the legs of most 55" TV stands. That said, it isn't very tall, so it doesn't block your TV screen unless your TV sits flush on the table.
The sub is the same size as the sub for the Vizio M Series M51a-H6. It's a bit shorter than the average desktop PC.
The satellites are fairly small. They need to be wired to the sub to get them to work, but they don't require a power cable, which is handy.
The Vizio M512a-H6 has a good build quality. The bar is mostly made of plastic, which feels solid and durable, and there's a metal grille on the top middle of the bar to help protect the up-firing speakers.

The Vizio M Series 5.1.2 has a great stereo frequency response. Out-of-the-box, the sound profile is quite balanced, especially in the mids, which is where most voices and lead instruments reproduce. As a result, you get an accurate, detailed reproduction of audio, making the bar suitable for listening to lots of different content. While the dedicated sub is small, it still brings plenty of rumble in the bass, so bass-heavy music and action-packed scenes have thump and power. Updating it to firmware version 2.1.0.4 makes little overall difference in the sound. You can customize its sound a bit thanks to its bass and treble adjustments.
The Vizio M Series 5.1.2 comes with bass and treble adjustments so you can customize its sound profile. However, if you prefer a more neutral sound profile, its default settings already have a slope within the ideal range.
The Vizio M Series 5.1.2 Soundbar has an impressive stereo soundstage performance. Its soundstage is perceived to be a bit wider than the bar itself, and its focus is very good. It's easy to pinpoint sound objects like voices and footsteps to an accurate location in the sound image.
The Vizio M Series 5.1.2 has an impressive stereo dynamics performance. The bar gets pretty loud, and there isn't a lot of compression when you push it to max volume. As a result, it's suitable for listeners who like to crank up the volume to fill up large spaces and crowded parties since your audio remains clean at loud volumes.
The Vizio M Series 5.1.2 Soundbar has a good stereo THD performance. At normal listening volumes, the amount of THD falls within good limits, resulting in clean and pure audio reproduction. There's a small jump in THD when the bar is pushed to max volume; however, this is hard to hear with real-life content.
The Vizio M Series 5.1.2 Soundbar has an excellent center channel performance. It comes with a discrete center channel which helps to more accurately localize voices within the sound image. It also has a neutral frequency response that's balanced in the mid-range, so vocal-heavy content like dialogue reproduces clearly and accurately. Updating the bar to firmware version 2.1.0.4 makes little difference in its center channel performance.
The Vizio M Series 5.1.2 Soundbar has a good surrounds performance. It has discrete surround speakers, so sound effects are clearly and accurately represented in the soundstage. Audio seems to be coming from all around you rather than just from speakers placed in front of you. Its frequency response is also slightly bass-heavy, so your audio content packs a little extra thump and punch. Updating the bar to firmware version 2.1.0.4 makes little difference in its surround channel performance.
The Vizio M Series Soundbar comes with two up-firing speakers built into the bar itself, which bounce sound off the ceiling and back down towards you to create the illusion of height. It's not quite as immersive as home theater setups with down-firing speakers on the ceiling, but it does better than soundbars without up-firing drivers, like the Vizio M Series M51a-H6. Sound effects are fairly clear in the mix, thanks to its balanced mids. You notice a little less rumble in the bass, especially with action-focused scenes like explosions and car chases. Updating the bar to firmware version 2.1.0.4 makes little difference in its Atmos performance.
Subjectively, the Vizio M Series 5.1.2 Soundbar performs well for its price, offering a fairly immersive sound, especially for average-sized living rooms. You don't have any trouble following the action on your screen, and the satellites add a nice touch, as sound effects seem to stretch the space around you. Compared to more premium setups like the Vizio Elevate, the bar doesn't achieve as much height. It doesn't seem like helicopters fly right over your head, for example. Instead, these sound effects just seem to come from the space in front of you. If you're willing to pay a little more, you can check out the Vizio M Series Elevate M512E-K6, which has rotating drivers to enhance the listening experience with Dolby Atmos content.
The Vizio M Series Soundbar has a decent selection of sound enhancement features. You can customize its sound using its EQ presets: 'Direct', 'Movie', 'Music', and 'Game'. Stereo files play from the bar and the subwoofer on all four EQ modes. When you play surround files on 'Direct' mode, audio plays from the subwoofer and the satellites. When you play surround files on 'Movie, 'Music', or 'Game' mode, audio plays from both the bar, the subwoofer, and the satellites.
The Vizio M Series 5.1.2 has a dialogue enhancement feature to make voices more clear and crisp and a night mode feature that helps balance the volume level across different programs. Unfortunately, compared to the Samsung HW-Q800B, it lacks more premium sound enhancement features like room correction, so it sounds different depending on the room you're listening in. You can still use its bass and treble adjustments to make up for this a bit, though.
The Vizio M512a-H6 comes with several physical inputs. There's a Full HDMI In port, meaning you can use it as a hub between different devices. However, even though the bar comes with a 3.5mm to RCA cable, there isn't an RCA In port, which can be disappointing if you want to use that connection to link your bar to your TV.
The Vizio M Series Sound Bar has incredible audio format support via ARC. It supports many different formats, including Dolby Digital, which is the most common surround sound format. It also supports lossless and object-based formats like DTS:X and Dolby Atmos.
The Vizio M512a-H6 also has fantastic audio format support via Full HDMI In. It supports Dolby Digital and DTS, which are commonly found on Blu-ray discs and streaming platforms. Also, it supports more premium object-based formats like DTS:X.
The Vizio M512a-H6 supports both Dolby Digital and DTS via Optical, which is handy for listeners who watch lots of Blu-ray discs and content from streaming platforms.
The Vizio M Series M512a-H6 has great latency performance. While its latency was fairly high at launch, updating the bar to firmware version 1.3.0.7 improves the latency over ARC, Optical, and HDMI In connections. The audio you hear is in sync with the video you see, so it's a solid choice for watching videos over these connections. Latency can vary based on different factors, including the apps and TV you use, so your experience may vary.
The Vizio M Series Sound Bar lets you wirelessly stream audio from your mobile devices to the bar via Bluetooth.
The Vizio M Series Sound Bar can passthrough the highest bandwidth signals. When connected between your PC and your TV, text on the screen appears clear and crisp.
This soundbar doesn't have an interface. Instead, a series of vertical lights on the left side of the bar flash different patterns depending on the settings you control. There's also some voice audio feedback when you change between one of the preset modes or change the input.
On top of the Vizio M Series Soundbar, there are physical controls that let you power the bar on/off, change the input, activate Bluetooth pairing, and adjust the volume.
The remote is fairly simple and lets you control all of the bar's functions. It even comes with a display screen.
The Vizio M Series Sound Bar has an AUX VA In port that lets you connect voice assistant-enabled devices like an Amazon Echo to the bar. However, this isn't considered built-in support since it requires that you purchase a third-party device.
