The LG SN9YG is a well-built 5.1.2 setup from 2020. Thanks to its wireless subwoofer, this soundbar has a bass-heavy but slightly boxy sound profile. It's still suitable for most audio content, and if you prefer a different sound profile, it has an outstanding amount of sound enhancement features to help tweak and customize it to your liking. Room correction is only available via the companion app, though. That said, it can get quite loud, and it supports Atmos content as well. It also has a wide array of physical inputs and wireless connectivity options, so it's easy to play your favorite content from the bar. You can even use it as a hub between your TV and another device like a gaming console. On the downside, there's distortion at max volume, but luckily, this can be hard to hear with real-life content.
The LG SN9YG is good for mixed use. Its bass-heavy sound profile is well-suited for action films and there are also several other EQ presets available to better suit your audio content if you prefer.

If you're using it for TV shows, it can reproduce dialogue clearly, and there are other features like room correction and dialogue enhancement available.

The LG SN9YG is a high-end 5.1.2 model from 2020. Just like other soundbars in the SN lineup, it has Meridian Technology built-in. It also uses up-firing speakers and a sub to produce a more immersive sound experience. The LG SN9YG's main competitors are the LG SL10YG, the Vizio SB36512-F6, and the Samsung HW-Q80R.
Just like the LG SL10YG, the LG SN9YG is a wide soundbar that looks sleek and sharp. It has a metal grille to protect its front and sides while there are two round metal grilles on its top to cover its up-firing speakers.
This sub has a fabric covering that protects its three sides which can get dirty or rip easily. The rest of the sub is made from hard plastic. The port is located on the back.
The LG SN9YG is a long soundbar and it won't fit between the legs of a 55" TV. Luckily, it shouldn't obscure your view if you place it in front of your TV unless the screen sits flush on the table.
The subwoofer is around the same size as an average desktop PC and it pairs wirelessly to the bar. You can place it anywhere in the room as long as you connect it to a power source.
There are no satellites in this setup.
The back of the soundbar has one opening for all of its inputs. There's also a power cable attached to the bar, but it can't be removed.
The back of the subwoofer is pretty plain. The port is found towards the bottom and it has a power cord right above it, which tends to stick out a bit.
The LG SN9YG has a great build quality. It's made from solid plastic and its metal grilles help to protect the speakers. However, the power cable is integrated into the bar and can't be removed. The subwoofer, in comparison, is mostly made from plastic. It has fabric covering three of its sides, which can collect dust or easily rip.
The LG SN9YG has a very good stereo frequency response. On 'Standard' mode, it has a bass-heavy sound that's a little boxy. That being said, it's still balanced enough for you to enjoy your favorite podcasts or albums. If you prefer a different sound, this soundbar has five EQ presets available as well. There's also a room correction feature that can further improve audio reproduction depending on the acoustics of your room, but this feature is only available via its companion app.
The stereo soundstage of the LG SN9YG is decent. While the bar is quite large, its soundstage is only about the size of the bar itself. That being said, it sounds focused, so objects come from accurate pinpoint locations rather than from a general area.
Update 09/21/2020: We've discovered a value input bug that would cause the Dynamics box results to be slightly off. All soundbars reviewed since January 30th, 2020 have been updated.
This soundbar has good stereo dynamics and it gets loud enough to fill a large or crowded room. It also performs well at max volume, so you won't get a lot of compression artifacts or thumping.
The LG SN9YG's THD performance is fair. It falls within good limits at a normal listening volume, resulting in a clear and pure sound. However, when you push the bar to its max volume, there's a big jump in THD, particularly in the bass and mid-range. That said, it may not be as audible with real-life content.
The LG SN9YG's center channel performance is great. Thanks to its 5.1.2 configuration, it has a dedicated center channel which results in clearer and more accurate audio reproduction of dialogue in movies. It doesn't get very loud, though, and it also sounds a little bass-heavy, but it shouldn't matter too much as there usually isn't a lot of bass on center channels.
The surround performance of the LG SN9YG soundbar is acceptable. It uses side-firing speakers to bounce sound off the walls, giving the impression of a wider surround sound. However, this setup won't provide the most accurate and clear representation of surround objects in its soundstage. It also won't feel as real as discrete surround produced by home theatre speakers.
The LG SN9YG supports Atmos, but its performance is poor. It uses up-firing speakers to bounce sound off of the ceiling, which helps to give the impression of height. That said, the localization of objects is diffused and it doesn't sound as real as discrete localization produced by down-firing speakers.
This soundbar has superb sound enhancement features. You can basically tweak everything and although it lacks a more comprehensive EQ, there are five EQ presets available to better customize your sound instead: AI Sound Pro, Bass Blast, Standard, Movie, and Music mode. There's also a room correction feature, but it's only available through the app. It should be noted that the dialogue enhancement feature only works on DTS-enabled content.
The LG SN9YG has a wide array of inputs, and it can even serve as a hub between your devices and your TV. However, it doesn't have an AUX port, so you won't be able to play audio from older devices.
The LG SN9YG has full audio format support via its HDMI ARC port. It also supports eARC, so it can play object-based surround signals and lossless formats.
The LG SN9YG has outstanding audio format support via its full HDMI In port. It supports all common audio formats including Dolby Atmos and DTS. You can also use it as a hub between external devices like a Blu-ray disc player and your TV.
This soundbar supports Dolby Digital and DTS content via its optical port. These formats are usually found on streaming platforms as well as on Blu-ray discs.
The LG SN9YG has outstanding wireless playback options. You can easily stream your favorite tunes or podcasts to it using Bluetooth or Wi-Fi. However, if you're using something with an iOS system, you won't be able to use Apple AirPlay.
The LG SN9YG can be connected between your TV and another source like your PC or gaming console to play 4k @ 60Hz. Text on your screen looks crisp and clear.
As this sub connects to the bar wirelessly, it only has an input for its power cable.
The interface is behind the front-facing metal grille towards the right-hand side of the bar. It displays the volume level using the four dots located under the screen, and it lets you know what current input you're on using text.
The LG SN9YG has touch-sensitive controls located towards the top of the bar. You can turn the bar on/off, change inputs, adjust volume, mic mute, and activate Google Assistant.
The LG SN9YG has a small and easy-to-use remote. You can control most of the bar's functions and settings when using the remote. However, you can only access the room correction feature by using the companion app.
The LG Wi-Fi Speaker is a simple app. You can turn on/off the room correction feature and control some things like volume. You can also access a sleep timer and control the bar's dynamic range. However, you can only adjust the bass and treble when using the remote.
