The Vizio SB36312-G6 is a 3.1.2 setup with a slim subwoofer that can be placed upright or on its side. On its standard 'Direct' mode, it has a boomy sound that some may find a little overwhelming for most audio content. It also lacks a dialogue enhancement feature, and it doesn't get too loud. While its volume level shouldn't be too problematic for most listeners, it has compression artifacts and pumping at max volume. On the upside, it has a full set of inputs so you can connect most devices to it, and you can stream audio to it using Bluetooth, Wi-Fi, or Chromecast built-in. There are also three EQ presets as well as bass and treble adjustment. It supports Atmos and DTS content too, but it has to downmix this content to stereo in order to play it.
The Vizio SB36312-G6 is disappointing for mixed use. It has a very boomy sound profile that can be overwhelming for movies and music.

On the upside, there's a couple of EQ presets as well as bass and treble adjustment available. It can also support Atmos and DTS content, which is nice.

Just like other 3.1.2 setups such as the LG SN8YG or Samsung HW-Q70R, it supports Dolby Atmos content by downmixing it into stereo, but its height performance isn't as good as soundbars with rear satellites.

The front and top of the bar are covered in fabric while the back and bottom of the bar are covered in good quality plastic. The silver ends of the bar give it a little more pizazz, but they're also made of plastic, which ends up making it look a little cheap.
This subwoofer has a very unique look. Its slim and tall body is made from MDF and there's a vinyl covering on top of it.

This sub can also be placed horizontally or vertically to better fit your space, which is nice.
The Vizio SB36312-G6 isn't very wide but you may still have difficulties placing it between the legs of a 55" TV, depending on its stand. However, it's not too tall, so unless your TV is flush to the table, it shouldn't obscure your view of the screen.
This subwoofer is extremely thin and is designed to fit into smaller spaces. You can also place it on its side if you find it's too tall for places like under shelves. You shouldn't have a problem placing it anywhere in the room, as it connects to the bar wirelessly.

The bar of the bar has two openings. The first one on the left is for its power cable, AUX, and Optical Audio inputs. The second opening on the right side houses the other inputs.

These two materials make the total setup feel solid and robust. Fabric covers the front and top sides of the bar while the sub only has a square of fabric covering the woofer. However, it feels like this fabric can be easily ripped or get dirty in either place. For a better-built soundbar, check out the LG SP7Y.

On its standard 'Direct' mode, it has a very boomy bass that overwhelms the mid and treble range which may be too much, even for fans of bass-heavy content like EDM or action films. Luckily, you can adjust its subwoofer level, and there are two other EQ presets to try out if you're looking for a different sound.
