Vizio M21D-H8R Review

The Vizio M21D-H8R is a sleek and angular soundbar that has a more understated design than most. It also comes at an affordable price. Is the understatement and the price going to cost the audio quality? 

To ensure your money goes toward a good product, our experts have conducted a thorough Vizio M21D-H8R review.



Vizio M21D-H8R Design

The Vizio M21D-H8R has a design our experts can’t stop raving about. The soundbar is slim, plain and angular, and fits minimalists’ tastes. The modern design hides some heavy duty hardware in the form of separate tweeters and woofers and built in subwoofers to fulfill your acoustic needs.


The 36-inch soundbar is also optimal for larger TVs from 40 inches and above. For a large soundbar, the weight does measure up at just over 8 pounds, but the slim profile doesn’t take up much space.

The M21D-H8R doesn’t come with a wall mounting system, but it can be wall mounted to save space. Otherwise, it’s easy to find it a home on a flat surface, thanks to its compact size.

Features of the Vizio M21D-H8R

Sound Quality

First of all, a single slim soundbar like this one often only features 2 channels or it can be a 2.1 but with an external subwoofer. The M21D-H8R is the ultimate space-saving option because it has the subwoofer built into the device.

Not only that, but the two-way soundbar has separate tweeters and woofers to project accurate highs and lows and they work together to make up for the mids. 

To help simulate the most realistic audio frequencies, the M21D-H8R has DTS Virtual:X to create a multi-dimensional soundstage to bring you dynamic sound. Once connected with HDMI, the M21D-H8R can also support Dolby 5.1 content.

Frequency Range

The frequency range of the Vizio soundbar is from 50 Hz to 20 kHz, taking care of the entire audio spectrum our ears can hear. You can also expect a lot of power and clarity from the M21D-H8R thanks to the 98 dB sensitivity and nominal impedance.

Vizio M21D-H8R Subwoofer

The Vizio M21D-H8R soundbar is a 2.1 channel device. This means it has a subwoofer. Unlike Samsung HW-KM36 with external subwoofer,  Vizio M21D-H8R’s sub is conveniently built-in. The dual 3-inch subwoofers will punctuate and enhance all the low bass notes from your woofers, as our experts have also experienced during this Vizio M21D-H8R review. You can expect low rumbles and heavy explosions from the M21D-H8R.


Our experts are happy to announce the Vizio M21D-H8R supports HDMI connection. HDMI is always our team’s first recommendation for wired connection. This is because it’s the easiest to hook up and it supports the highest quality content.

Luckily for consumers, the M21D-H8R comes with all you need to get set up in minutes. The HDMI cable comes with your package and is a plug and play design.

Wireless Connectivity

For wireless connection, the M21D-H8R supports Bluetooth [1]. Bluetooth is a ubiquitous form of wireless connection that will ensure the soundbar’s compatibility with most media devices you have.

You can stream content from your computer making it an ideal soundbar for PC, too! Or  content from your tablet or phone through the Bluetooth soundbar and enjoy high quality audio.

Voice Assistant Ready

The M21D-H8R is voice-assistant ready, which means you can configure the soundbar to work with a voice assistant device you are accustomed to using. You can control everything through the soundbar, which brings a new level of convenience to the usability of the soundbar.

Vizio M21D-H8R Price

With so many inviting features, the M21D-H8R is a very affordable soundbar for what you get. You have subwoofers already embedded in the device and advanced audio technologies from DTS to support high quality content. 

When you take into account the convenience of the voice-assistant ready soundbar and the HDMI connection, you know you are really getting your money’s worth and more. Our experts believe whole-heartedly that the M21D-H8R is an excellent soundbar for the price.

Vizio M21D-H8R Review Conclusion

After a careful Vizio M21D-H8R review, our expert team has concluded that the soundbar is an absolute find. The price is affordable and the subwoofer comes with separate tweeters, woofers and subwoofers to boost the bass. You can enjoy enhanced sound from your media devices by connecting to Bluetooth and everything can be easily controlled with your voice assistant device.

All you need to set up the M21D-H8R is included in the box and you can go from unboxing to enjoying your new soundbar in a matter of minutes.
