Channels
3.1

The LG SN6Y is a fairly ordinary 3.1 channel soundbar setup. Its standard sound profile is fairly bass-heavy, although it lacks the deep rumble you find in action movie sound effects or electronic music. It has a dedicated center channel for clearer voices and dialogue, but it can also sound a bit harsh. It also does a poor job downmixing surround content, making the surround channels overly bass-heavy, and doesn't support Dolby Atmos. On the upside, it gets quite loud without compressing very much. It also has a number of sound customization features so you can tweak the way it sounds a bit to better suit your needs. You can also purchase a rear speaker kit to transform it into a 5.1 setup, though we haven't tested this.

Our Verdict

6.6 Mixed Usage

The LG SN6Y is okay for mixed usage. Its standard sound profile isn't the best-balanced - it sounds quite bass-heavy, but also a bit harsh at times. The subwoofer also struggles to produce the deep rumble of action film effects as well. That said, it has a decent number of sound customization options to help its sound better fit your needs. It also has excellent center channel performance that helps make dialogue in movies and TV shows clearer.

Pros
  • Excellent center channel performance.
  • Good stereo dynamics.
  • Premium design.
Cons
  • Surround downmixing is overly bass-heavy.
  • Wireless playback options limited to Bluetooth.
  • Companion app, including certain features, only functional on Android.
6.9 Dialogue/TV Shows

The LG SN6Y is alright for dialogue and TV shows. While its standard sound signature is rather bass-heavy, it has a dedicated center channel that helps make dialogue sound clearer. This channel doesn't get as loud as the rest of the bar, but it does overemphasize certain frequencies, which makes voices sound more present, but also a bit harsh.

6.8 Music

The LG SN6Y is decent for music. It has a fairly bass-heavy sound profile with lots of kick and punch that fans of EDM or hip-hop often enjoy. It does make some instruments and vocals sound rather harsh, though. On the upside, there are both bass and treble level adjustment options for you to tweak the sound profile a bit. It can also get quite loud without compressing too much, which makes it suitable for parties.

6.3 Movies

The LG SN6Y is passable for movies. Since it comes as a 3.1 soundbar setup by default, 5.1 surround sound content is downmixed to stereo, so you don't get a very immersive listening experience. It doesn't support Dolby Atmos, either. Action films lack rumble with the standard sound setting, but there are some customization options to better suit your tastes. You can also purchase a rear speaker kit to transform it into a 5.1 setup, but it still doesn't support Atmos.

The LG SN6Y is a mid-range 3.1 soundbar from LG's 2020 lineup that replaces the LG SL6Y. Like its predecessor, the SN6Y setup only comes with a soundbar and wireless subwoofer. It's not as feature-packed as LG's more premium models, but it's their most affordable option for those who want a dedicated center channel. You can also upgrade it to a 5.1 setup with LG's SPK8-S rear wireless speaker kit, which is sold separately. Its main competitors are the Samsung HW-T650 and the Sony HT-G700.

Design
Design
Style - Bar

The LG SN6Y is virtually identical to its predecessor, the LG SL6Y. It has a simple, straightforward design with a classic, traditional soundbar style that doesn't stand out in any particular way. It has a metal grill covering the front of the bar while the rest is made of plastic. The top is embossed to give it a faux-leather look and feel, and the LG logo is visibly printed in white near the right-hand corner.

Design
Style - Subwoofer

The LG SN6Y's subwoofer remains similar in design to that of the LG SL6Y, but with a few differences. The front of the sub is still covered in fabric, but the top is now coated in plastic. The LG logo is also now on the top of the subwoofer.

Dimensions - Bar
Bar Width 41.7" (106.0 cm)
Bar Height 2.2" (5.6 cm)
Bar Depth 3.4" (8.6 cm)

The LG SN6Y is a fairly wide soundbar, so it's unlikely to fit between the legs of most 55" TVs. On the upside, the bar isn't very tall, so it shouldn't obstruct the view of your screen if it's placed in front, unless you have a TV that sits flush on the table.

Design
Dimensions - Subwoofer
Sub Width 7.1" (18.1 cm)
Sub Height 15.4" (39.2 cm)
Sub Depth 11.5" (29.2 cm)

The LG SN6Y's subwoofer is a bit larger than the LG SL6Y's, but it's still not too large overall. It's around the same size as a large desktop PC, but it shouldn't be too difficult to find a spot for in your TV room.

The back of the LG SN6Y soundbar has an opening on the side for you to access the inputs. The power connection is on the other side. The universal wall-mounting holes are on the underside of the soundbar.

Ported

The back of the LG SN6Y's subwoofer is markedly different than that of the older LG SL6Y. The port is more pronounced and the pairing button is more evident. The power cable also uses a right-angle connector, which helps keep the cable from bending if the back of the sub is placed next to a wall.

Build Quality

The LG SN6Y is a well-built subwoofer. Nothing seems to have changed from the previous year's model, the LG SL6Y. The bar is still made of plastic, with a metal grill covering the front that gives a nice look and feel. The front of the subwoofer is covered in fabric, which tends to collect dust and is prone to rips or tears.

The LG SN6Y has an acceptable stereo frequency response. Compared to the older LG SL6Y, it's quite a bit more bass-heavy. Although it still struggles to produce the deepest rumbles of explosions or electronic music, it has a lot more thump and punch. The mid-range is decently neutral, but the over-emphasis in mid-mid and low-treble make instruments and vocals it sound a bit forward and harsh. It also sounds a bit too bass-heavy on some songs, so overall, its sound profile isn't the best-balanced.

The LG SN6Y has a decent stereo soundstage. It has good focus, which makes it easy to pinpoint the location of objects in the sound image. However, it only feels about as wide as the bar itself, so there isn't a noticeable improvement over the older LG SL6Y's soundstage.

This soundbar has good stereo dynamics. It can get even louder than its predecessor, the LG SL6Y, which is great when you're throwing a party. However, it also compresses more audibly, especially in the bass range.

This soundbar's stereo total harmonic distortion performance is decent. At normal listening volumes, there's little distortion. However, when you push this soundbar to max volume, it distorts quite a bit more. However, distortion isn't noticeable to everyone, especially when it's most prominent in the bass range, like with this soundbar.

This soundbar's center channel performance is remarkable. Since it's a 3.1 soundbar, it has a discrete center channel, which helps dialogue in movies and TV shows sound clearer. While it doesn't get as loud as some other options like the Klipsch Bar 48, the extra boost in the low-treble helps make voices still sound adequately present. However, this can also sound a bit harsh to some.

The LG SN6Y is a 3.1 soundbar, so it doesn't have surround channels. Surround content is downmixed to stereo and distributed between the front three speakers. This means you don't get the effect of real surround sound; instead, you feel like the sound just comes from out in front of you. This soundbar's downmix is also particularly bass-heavy, resulting in a poor surround experience.

The LG SN6Y has a decent number of sound enhancement features. There are a few different sound effect options, like LG's AI Sound Pro feature and DTS Virtual:X surround.

The LG SN6Y has the same input options as the older LG SL6Y. There's an HDMI ARC port to connect to your TV and a full HDMI-IN for your gaming console or Blu-ray player. You can also connect to your TV via optical and play music off a USB flash drive. It doesn't have a 3.5mm aux port, though, which makes playing music off a turntable or older MP3 player more complicated.

Compared to other soundbars

The LG SN6Y is a mid-range 3.1 soundbar, replacing the LG SL6Y. It's a passable soundbar overall, but doesn't stand out much among the competition. It sounds alright overall, but isn't as well-balanced as the Samsung HW-R650. While it supports the major surround sound formats, it doesn't support Atmos like the Sony HT-Z9F. That said, it does 4k passthrough, and has a number of sound customization features, which many other 3.1 soundbars lack. If you want to consider more options, check out our recommendations for the best soundbars, the best soundbars with a subwoofer, and the best soundbars for music.

Yamaha YAS-209
SEE PRICE
Amazon.com

The Yamaha YAS-209 is a better overall soundbar setup than the LG SN6Y, even though it has fewer channels. The 2.1 Yamaha has a much more neutral, balanced, default sound profile. Although the 3.1 LG has a discreet center channel for clearer dialogue, its subwoofer doesn't rumble very much, making it less versatile for movies and music. The Yamaha can also play music wirelessly over a Wi-Fi connection, unlike the LG which is limited to Bluetooth wireless playback.

LG SN8YG
SEE PRICE
BestBuy.com

The LG SN6Y and the LG SN8YG are similarly well-built soundbars but the LG SN8YG performs slightly better overall. The SN8YG's wireless subwoofer can produce a more thumpy bass, it can support Dolby Atmos as well as eARC content, and it has a room correction feature. You can also use Chromecast built-in or your Wi-Fi to connect to the bar, and it has Google Assistant integrated into its design so you can use vocal commands to control your soundbar. The SN6Y, on the other hand, has slightly less distortion at max volume, and if you're limited on space, its subwoofer isn't as wide.

Sony HT-Z9F
SEE PRICE
Amazon.com

The Sony HT-Z9F is a better 3.1 soundbar setup than the LG SN6Y. The Sony has a more neutral default sound profile, supports more surround sound formats, including Dolby Atmos, and has more wireless playback options like Chromecast and AirPlay. It has less sound customization options than the LG, however. If you don't care as much about surround support and prefer being able to customize the way your soundbar sounds, the LG may be a better option.

Samsung HW-Q90R
SEE PRICE
Amazon.com

The Samsung HW-Q90R is a much better, more complete soundbar setup than the LG SN6Y. The Samsung uses a 7.1.4 channel configuration, which results in a much more immersive listening experience than the 3.1-channel Sony. The Samsung also supports Atmos, and its subwoofer produces more bass for action movies or electronic music. The LG is much more compact, though, which makes it a better choice if you're tight on space.

Samsung HW-R650
SEE PRICE
Amazon.com

The Samsung HW-R650 is a better 3.1 channel soundbar setup than the LG SN6Y for most people. The Samsung has a better-balanced default sound profile, more sound enhancement features including a full graphic EQ, and better stereo dynamics. However, it can't passthrough 4k video, so the LG is a better option if you'd like to use your soundbar as a hub between your TV and 4k content sources, like a Blu-ray player or gaming console.

Klipsch Bar 48
SEE PRICE
Amazon.com

The LG SN6Y is a more versatile 3.1 channel soundbar than the Klipsch Bar 48. The LG produces more bass, has more sound enhancement features, and has a full HDMI-in port so you can use it as a hub between your TV and home media devices. However, the Klipsch gets much louder, which makes it worth considering if you need something for parties or a very large room.
