Explore more about the VIZIO M-Series here to see if it’s the right fit for your entertainment space.

Overview of the VIZIO M213AD-K8

The VIZIO M-Series aims to deliver immersive audio with its integrated speakers and built-in subwoofers. This model, the M213AD-K8, also known as the M Series All-in-One (AiO) Sound Bar, includes Dolby Atmos and DTS Virtual:X technologies, which can create a sense of depth and a layered sound environment without the need for speakers to be physically placed across the room.

It offers excellent sound quality for movies and music, with impressive bass response and dialogue clarity. Key features of the soundbar include:

  • Dolby Atmos Support: The soundbar supports Dolby Atmos, but it is limited in its capabilities.
  • Integrated Subwoofers: Two integrated subwoofers improve the bass reproduction.
  • Design: The soundbar has a simple and sleek design, but it is considered drab and unattractive by some users.
  • Connectivity: It offers two HDMI inputs, one HDMI eARC/ARC, one digital optical input, one 3.5mm auxiliary input, one 3.5mm stereo input, and one USB input.
  • Bluetooth 5.2: The soundbar supports wireless connection via Bluetooth 5.2.

However, the soundbar has some limitations, such as no Wi-Fi streaming and no real Dolby Atmos effects. Overall, it is a great option for those looking for an affordable soundbar with good sound quality, but it may not be the best choice for those who prioritize Dolby Atmos support.

Design and Build Quality

Vizio took a balanced approach to design with this soundbar. The minimalist and discreet aesthetic is designed to blend seamlessly into a variety of living spaces. With integrated dual subwoofers, the unit eliminates the need for external speakers, maintaining a clean look.

The build quality is good, despite Vizio’s reputation as an affordable brand. The choice of materials is no worse than the competition, and at 36 inches in width, the sound bar is compact enough for easy placement under most televisions. Its fabric-wrapped exterior contributes to an upscale look while also serving a functional purpose by protecting the speakers.

Installation is designed to be user-friendly. The sound bar’s low-profile design, just over two inches in height, ensures it doesn’t obstruct the TV screen—ideal for viewers who prefer an unobtrusive setup. While we have no personal experience in setting up this particular model, it seems the brand has considered ease of use in its all-in-one design.

Sound Quality

The M213AD-K8 delivers a well-balanced stereo frequency response. While it may not rival the experience provided by high-end home theater systems, the M-Series holds its own in its category, offering an immersive listening environment. This is credited to the 2.1 setup, which, though modest, performs well for the average living room.

When it comes to bass response, the built-in subwoofers pack a punch. The low-frequency sounds are robust without overwhelming the mid and high tones, enhancing action scenes in movies or the beat in music genres that rely heavily on bass. They won’t, however, be capable of reproducing the lower frequencies that even fairly basic external subwoofers produce, so keep that in mind if you plan to watch a lot of movies with it.

Dialogue clarity is very good. The sound bar manages to bring out speech and vocals clearly, ensuring that conversations in films or vocal performances in music can be heard distinctly. This is particularly important in dialogue-heavy content where audio fidelity can greatly affect the viewing experience.

Overall, the sound quality strikes a fine balance—powerful enough to enrich a casual viewer’s auditory experience without the complexity that might accompany more elaborate setups.

Features and Connectivity

The AIO soundbar’s emphasis on audio technologies like Dolby Atmos and DTS to be a significant draw. These features aim to envelop listeners with sounds that seem to come from all directions, enhancing the immersive experience. There’s also the added benefit of DTS Virtual:X which, even without physical height or rear speakers, attempts to simulate an enveloping soundscape.

However, it’s important to note that the Vizio M Series M213ad-K8 soundbar’s Dolby Atmos support is limited in the following ways:

  1. Downmixing: The soundbar has to downmix Dolby Atmos content into stereo to play it, which means it cannot fully reproduce the immersive, multi-dimensional sound experience that Dolby Atmos is designed for.
  2. No Up-firing Speakers: The M213ad-K8 does not have up-firing Dolby Atmos speakers, which are typically used to bounce sound off the ceiling and create a more immersive audio experience.
  3. Limited Expansion: The soundbar cannot be expanded with additional speakers, which would further enhance the Dolby Atmos experience.

Despite these limitations, the Vizio M213ad-K8 still offers excellent sound for movies and music, especially considering its budget-friendly price.

Another standout feature is the HDMI eARC support. This allows high-quality audio signals to be sent back to the sound bar from the TV, simplifying the setup and reducing the number of cables needed. The unit’s Bluetooth connectivity is handy for streaming music from mobile devices, adding to its versatility.

However, it’s worth mentioning that the connectivity options are limited compared to some other models, with no mention of multiple HDMI input ports. This could be a drawback if you have several devices to connect. As far as connectivity goes, it seems the focus here is on simplicity and ease of use, potentially at the expense of expandability.


Overall, the VIZIO M-Series 2.1 sound bar offers a balanced profile for those seeking an upgrade to their audio experience. Its 6 high-performance speakers, coupled with Dolby Atmos and DTS, contribute to an immersive listening environment that many users find enhances their viewing sessions. The integrated subwoofers deliver a satisfactory bass response, which only feels lacking when watching movies with rumbling bass.
