LG SN9YG vs LG SP8YA: Which Soundbar is Better?

design small Reviews

After realizing how fun and didactic it would be to express my opinion on the two amazing LG products: SN9YG and SP8YA, I found it irresistible to assess each of them to show which one is the better soundbar solution. To be candid, I found both to be highly functional with great features.

I was a little bit surprised when I discovered that just as SP9YA happens to be the next generation of LG SN9YG, so is LG SP8YA. The most difference between SN9YG and SP8YA is that the former features a 5.1.2 setup with a rated power of 520 watts, whereas the setup of SP8YA is 440 watts. I fell in love with both soundbar solutions when I tested each of them and see how amazing their features really are, in particular, their Bass Enhancements (I really enjoyed all my action films), EQ Presets, Treble Enhancements, and lots more.

Furthermore, before I move into the subject matter in detail, I discovered that listening habits could influence preference as far as the 5.1.2 LG SN9YG and the 3.1.2 LG SP8YA are concerned.  Looking at the former, I saw it to be better built and playing surround content and not downmix it to stereo.  Nonetheless, I discovered that SP8YA comes with more wireless playback options. Besides, it can get louder, but with more compression at maximum volume.

Here are the major differences between these two soundbars:



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 soundbar doesn’t have satellites.


The LG SP8YA is a simple soundbar with a similar design to the LG SN8YG. It’s mostly made of plastic, with metal grilles covering the front of the bar and the up-firing speakers on top of the bar

This setup doesn’t come with satellites, but you can purchase LG SPK8 rear speakers separately.

Dimensions Bar and Subwoofer:


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.

  • Width: 48.0″ (121.9 cm)
  • Height: 2.2″ (5.6 cm)
  • Depth: 5.7″ (14.4 cm)

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.

  • Width: 7″ (22.1 cm)
  • Height: 4″ (39.0 cm)
  • Depth: 3″ (31.2 cm)


The LG SP8YA soundbar is fairly wide, so it likely won’t fit between the legs of a 55″ TV. However, it isn’t very tall, so it shouldn’t block your TV screen unless your TV sits flush on your table.

  •  Width: 7″ (106.0 cm)
  • Height: 2.2″ (5.6 cm)
  • Depth: 7″ (12.0 cm)

The sub is about the size of an average desktop computer. It connects wirelessly to the bar, so you have some flexibility in where you place it in your room.

  • Width: 7″ (22.1 cm)
  • Height: 4″ (39.0 cm)
  • Depth: 3″ (31.2 cm)

Back Bar and Subwoofer:


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 back of the bar has an input for the power cable as well as an opening for the inputs. There are also universal holes on the underside, so you can wall-mount the bar.

The back of the sub has a plastic port. There’s also an input for the power cable.

Build Quality and in the Box:


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 soundbar 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.

  • Tested Present: Standard
  • Slope: -0.71
  • Err.: 3.30 dB
  • Low-Frequency Extension: 29.5 Hz
  • High-Frequency Extension: 19.9 kHz

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.

  • Crosstalk Error: 2.53 dB

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.

  • SPL @ Max Volume: 89.5 dB SPL
  • DRC @ Max Volume: 0.95 Db

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 THAT, particularly in the bass and mid-range. That said, it may not be as audible with real-life content.

  • Weighted THD @ 80dB: 0.67
  • Weighted THD @ Max Volume: 3.62

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.

  • Localization: Discrete
  • Slope: -0.53
  • Err.: 4.37 dB
  • SPL @ Max Volume: 87.4 dB SPL
  • Weighted THD @ 80dB: 3.73
  • Weighted THD @ Max Volume: 6.56

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.

  • Localization: Phantom (Side Firing, Bar)
  • Slope: 0.13
  • Err.: 5.99 dB
  • SPL @ Max Volume: 92.8 dB SPL
  • Weighted THD @ 80dB: 1.58
  • Weighted THD @ Max Volume: 3.32
  • 1 Rears: No


The LG SP8YA soundbar has a great stereo frequency response. It comes with a room correction feature called AI Room Calibration that automatically optimizes audio reproduction based on the room you’re listening in. With this feature turned on, it has a bass-heavy sound profile that adds extra thump and punch to your audio, so you feel the rumbles in action-packed movies and bass-heavy music.

The rest of the range is fairly balanced, making it suitable for dialogue-centric content like podcasts and TV shows. However, since room correction relies on the acoustic capacities of your room, our results may be unique to our testing room. There are also bass and treble adjustments as well as some EQ presets to help you customize its sound.

  • Tested Present: Standard
  • Slope: -0.58
  • Err.: 3.43 dB
  • Low-Frequency Extension: 31.3 Hz
  • High-Frequency Extension: 19.9 kHz

The LG SP8YA soundbar has a decent stereo soundstage performance. The soundstage is perceived to be a little bit wider than the bar itself, but it doesn’t have any tricks to make it sound wider than that. The focus, however, is just decent. Objects like voices and footsteps seem to come from a more general area rather than from an accurate, pinpoint location.

  • Crosstalk Error: 2.15 dB

The LG SP8YA has a great stereo dynamics performance. It gets pretty loud, and there isn’t a lot of compression when you play it at max volume. As a result, it’s suitable for turning up the volume for parties or listening in large rooms.

  • SPL @ Max Volume: 93.0 dB SPL
  • DRC @ Max Volume: 1.19 dB

The LG SP8YA has a satisfactory THD performance. At normal listening volumes, the amount of distortion falls within good limits, resulting in clean and pure audio reproduction. At max volume, there’s a jump in THD, especially in the bass to mid-range. This may not be noticeable with real-life content, though.

  • Weighted THD @ 80dB: 0.53
  • Weighted THD @ Max Volume: 2.59

The LG SP8YA soundbar has an amazing center channel performance. This 3.1.2 setup comes with a dedicated center channel, which helps to reproduce dialogue more clearly and accurately in movies and TV shows. Its frequency response is quite balanced, too, especially in the mid-range, so voices are reproduced clearly and with detail.

  • Localization: Discrete
  • Slope: -0.13
  • Err.: 2.11 dB
  • SPL @ Max Volume: 89.6 dB SPL
  • Weighted THD @ 80dB: 0.53
  • Weighted THD @ Max Volume: 2.59

The LG SP8YA has a poor surrounds performance. It has to downmix surround content into stereo to play it, so sound objects like voices and footsteps aren’t as accurately localized in the soundstage. Audio seems like it’s coming from in front of you rather than from speakers placed all around you.

  • Localization: Stereo (Downmix)
  • Slope: -0.64
  • Err.: 3.44 dB
  • SPL @ Max Volume: 93.2 dB SPL
  • Weighted THD @ 80dB: 0.47
  • Weighted THD @ Max Volume: 2.53
  • 1 Rears: No
