For our review, we are going to look at the design and features in detail for the SB3820-C6 soundbar.


The Vizio 38 sound bar measures at 38 inches, making it great for larger TVs. Almost all Vizio sound bars have one thing in common, and that’s the sleek and modern design that fits into any living room. 

The sleek design almost makes it difficult to tell this high quality piece of equipment is a soundbar. It blends in with your TV and can be mounted on the wall or placed on a cabinet or entertainment unit. Since it’s sleek and slim, it takes up less space than other bulkier soundbars.

The mounting kit comes with the package and for larger sound bars, the Vizio SB3820-C6 is relatively lightweight, coming in at just 2.61kg.


Sound Quality

There is a reason why this sound bar receives a rating of 5 stars in our Vizio SB3820-C6 review, and that is the most important quality of all – great sound. The addition of the DTS TruVolume in the Vizio SB3820-C6 can give a cinematic experience to your own home theater.

Just like other amazing soundbars, this model is capable of pumping out 100 dB of clear sound with minimal distortion (total harmonic distortion is less than 1%) even at high volumes. 

Although you may not always turn up the content to reach 100 dB and most people keep them at save decibel levels [1], it’s useful to know that this particular sound bar can balance all audio sounds in the mid and upper ranges.

Full Range Drivers

The drivers, or speakers, are full range capable of reaching the entire scale of notes a human voice can emit and our ears can detect. The speakers give audiences a great realistic take on the sound that vibrates through the room.


As for how to pair your soundbar to your TV, the SB3820-C6 sound bar offers quite a few choices.

It features a whopping 7 options to connect that include: the subwoofer output (this is meant for the external subwoofer output), the digital optical cable input, the coaxial cable digital audio input, auxiliary cable 3.5mm, the  stereo RCA, power input and the USB port.

This gives users the versatility to connect different devices they want with different inputs, which also makes this Vizio sound bar the most diverse.


The sound bar itself is already capable of producing superb bass tones (equipped with deep bass modules), which renders an extra wireless subwoofer unnecessary. 

In our review, we found that you’ll already receive a dynamic audio experience with the Vizio soundbar alone, but for those audiophiles who love to tweak the sound and are looking for that deep bass performance, you can use a top external subwoofer.

Bluetooth Connection

The sound bar works with any device that supports Bluetooth. If you want to stream music from your mobile device, just pair it with the Vizio SB3820-C6 sound bar and let the audio fill the room.

Bluetooth connection is also useful if your TV can pair with your Vizio sound bar via Bluetooth as well. This will minimize the mess and clutter of wires that are easy to get tangled. 

If you’re looking for deep bass and require an external subwoofer, then Bluetooth connection is also your best bet. A subwoofer will improve your home theater and will only require Bluetooth to pair. 

An external subwoofer can be quite large and take up a lot of space than you’d like. If you are able to place the subwoofer where it suits you and out of the way and not have it wired to your stationery TV, it will provide you with the placement flexibility you want for the sound system.

Surround Sound

One prevailing comment in many customer reviews is the surround sound that the sound bar has in place.

The sound bar operates at a 60 Hz to 19 kHz frequency. Complete with top Dolby Digital technology (Dolby Digital, DTS Studio Sound ™, DTS TruVolume ™, DTS TruSurround ™, which is the industry-leading standard in surround sound, you can hear all the different levels of sound as each note is more defined each time.

The DTS TruSurround allows the Vizio soundbar to recreate realistic sound effects that bring the content played on your screen to life. You will feel like you are not only an audience member watching events unfold, but it will almost seem like you are a part of the performance through the speaker.

TruVolume ensures you get great sound all the time in this 38-inch 2.0 channel sound bar. As a part of the best home theater system experience, you’ll get to enjoy consistent audio volumes and well-balanced audio performance. You’ll find the True Volume makes sure you only get to set your volume once. 

Easy to Set Up and Install

It’s difficult to install a piece of technology as it is extremely time consuming and can be disheartening.

The Vizio SB3820-C6 soundbar doesn’t pose this problem. It’s very easy to set up under your TV or on your wall. It features everything you need right out of the box, which makes it great for the price. That’s also one comment we see in many customer reviews.

If you happen to encounter any problems while using your soundbar, the simple to understand user manual is ready for troubleshooting.

Other contents of the box include the remote, one power adapter, one coaxial power cable type, one digital optical cable type, and the RCA and 3.5 mm cable plus all that you need to use for wall mounting.


This is the Vizio SB3820-C6 38-inch 2.0 channel sound bar. For those that aren’t familiar, 2.0 sound bars are ones with two channels. 2 channel soundbars mean you have two points of sound emission on your soundbar.

The Vizio SB3820-C6 soundbar is a great 2 channel soundbar equipped with two full range speakers that will boost existing audio.

A 2 channel soundbar will emit penetrating sound from the left and right speakers. In order to simulate immersive and expansive audio, the industry standard to achieve this would require a soundbar to have 5 or more channels or speakers.

However, since your Vizio SB3820-C6 38-inch 2.0 channel sound bar is using the most advanced sound system of all, (Dolby Digital DTS), the 2 channels would suffice for room-filling sound experience from the wall.

Remote and Controls

The Vizio SB3860-C6 comes with a remote control in the package, but if you already use a universal one, it could pair with the system as well. Aside from the remote control that allows you to input speaker settings without having to get up, there is also a control panel built right onto the soundbar.

On the control panel of the audio system, you can find the on/off power button, the two-volume controls for increasing and decreasing your speaker sound levels (which can also be used to control the external subwoofer), input control, and the Bluetooth input button.


The warranty is a feature that comes with the speaker product. The manufacturer offers a 1-year warranty that comes with your sound bar. One great thing about having a warranty, guarantee, or both is the peace of mind it provides.

Just in case you find a faulty product or something else undesirable in the speakers, it does give you the option to exchange and replace the existing one for another. So aside from considering the price and reading reviews, it’s best to search or look for a warranty when you buy a product.

Vizio SB3820-C6 Review Conclusion

The Vizio SB3820-C6 38-inch 2.0 channel sound bar is a top device that provides 100 dB of high-powered, high quality, and virtually distortion-free sound. For people looking for a soundbar that pairs well with a TV larger than 38 inches that fit in with any interior decor, this is the one to get for your system.

It offers the highest standard for surround sound in the industry with Dolby DTS. You will be able to experience the height of cinematic sound with this amazing soundbar. Overall, it’s great for the price.
