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 compare each of them to find out which is the best soundbar. As far as I can tell, both were really functional and had some great features.

I was a little bit surprised when I found out that LG SP9YA is just the latest model of my LG SP8YA. The most difference between SN9YG and SP8YA is that the setup of SP8YA has 440 watts where as the 5.1.2 set up of PC is 520 watts. I was pleasantly surprised by the sound quality and features of both soundbars I tested. The bass enhancements were especially great for action films and the EQ presets and treble enhancements made dialogue really easy to understand.

There’s been a lot of talk lately about how listening habits can influence a person’s preference between 5.1.2 LG SN9YG and 3.1.2 LG SP8YA speakers. From my perspective the former is a better built speaker and for stereo content it’s not downmixing to mono. The SP8YA comes with a lot more wireless playback options. Plus, it can get louder but with a lot of compression when maxing out the volume.

These two soundbars are similar, but there are a few notable differences between them.

Design:

LG SN9YG

The LG soundbar was made to look sleek, sharp and unique with a metal grille on the front. It also has a metal-wrapped side with up-firing speakers that covers two smaller ones.

This speaker doesn’t have anything to blast loud music in your room with, it’s just the main soundbar.

LG SP8YA

The LG SP8YA is designed to function as a speaker for your TV. There is a similar design on the LG SN8YG, with mostly plastic and metal surfaces.

This speaker doesn’t come with satellite speakers, but you can make up the difference by purchasing LG SPK8 rear speakers separately.

Dimensions Bar and Subwoofer:

LG SN9YG

The soundbar is too long so it won’t fit between the legs of a TV. But if you put it in front of your TV, it shouldn’t be that big an issue as long as the screen doesn’t mess up your viewing angle.

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

The subwoofer is about the same size as a desk PC and it pairs with the bars wirelessly. You can put it wherever 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)

 LG SP8YA

The LG SP8YA soundbar is on the wider side, so it won’t fit between the legs of a 55″ TV. However, it isn’t very tall, so you should be able to avoid blocking your TV screen.

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

The sub is the size of an average desktop computer. It connects wirelessly to the bar, and there are so many places where you can put it to accurately achieve the best sound.

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

Back Bar and Subwoofer:

LG SN9YG

The back of the bar is where all the cords are connected. You can’t take this cable off, but it comes with its own power cord in case you don’t have any extra ones lying around.

The back of the subwoofer is pretty plain and since there’s no controls it can take some trial-and-error to adjust the settings. The port is located near the bottom, which may cause problems for taller ears.

LG SP8YA

You can plug the power cable at the back of the bar and put in inputs with universal holes on the bottom so you can mount it to a wall.

The back of the sub has a jack for the power cord and a port for your connection cable.

Build Quality and in the Box:

LG SN9YG

The LG SN9YG has a great design. It’s made from solid plastic and its metal grilles will protect the speakers. The power cable is integrated into the bar but can’t be removed. The subwoofer, on the other hand, is plastic-made with fabric covering three of its sides. It’s easy to accumulate dust or tear it.

LG SP8YA

LG’s SP8YA soundbar has a good build quality. Most of it is made out of plastic, which feels solid and durable. The metal grilles help to protect the drivers as well. The sub is also made of high-quality plastic, but the fabric covering seems like it could get ripped or dirty easily.

Sound:

LG SN9YG

The LG SN9YG soundbar has a good stereo frequency response. On the ‘Standard’ setting, it has a bass-heavy sound that’s a little boxy at times and tends to vibrate on surfaces. It’s perfect for your favorite podcasts or albums, but can also be adjusted to another sound. With five different EQs, you can choose to listen the way you want. There’s also a room correction feature that can theoretically improve your audio quality depending on the acoustics of your room, but you’ll need to download the App to use it.

  • 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 pretty good, though it is quite small. The width of the bar is just as broad as its soundscape, but it sounds pretty focused. Sounds come from accurate point sources rather than from a general area like with most bars or speakers.

  • Crosstalk Error: 2.53 dB

We found a bug where the box results were off from 30th Jan 2020. All soundbars reviewed after that date have been updated.

This soundbar has great stereo sound and gets very loud. You can fill a large/crowded room with good sound without much distortion at full volume.

  • 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 clean sound. However, if you crank it up to max volume there’s this huge boost in clarity. In particular, the bass and mid-range sounds so much more present from that point on. It might not be as noticeable with your average day-to-day content though.

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

The LG SN9YG’s center channel is pretty great. Thanks to the 5.1.2 configuration, there’s a dedicated center channel that produces clearer and more accurate dialogue reproduction in movies. It doesn’t get very loud and can sound somewhat bass-heavy, but it’s not a huge problem as there usually isn’t a lot of noise 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 sound quality of the LG SN9YG soundbar is alright. It has side-firing speakers that bounce the sound off the walls, making it seem like it’s coming from a wider angle than just in front of you. Another downside of this setup is that it won’t sound as natural as if you had discrete surround speakers installed in your living room.

  • 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

LG SP8YA

The LG SP8YA soundbar offers a wide stereo frequency range. The soundbar also features AI Room Calibration, which automatically optimizes audio reproduction depending on where you are listening. This feature activates a bass-heavy sound profile, which adds extra thump to your audio. It’s perfect for showcasing action-packed movies or listening to bass-heavy music.

The remainder of the range is quite balanced and suitable for dialogue-centric content such as podcasts or TV shows. Our results might be different because room correction depends on the acoustic capabilities of your room. You can also adjust the bass and treble of your room with some EQ presets.

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

The stereo soundstage performance of the LG SP8YA soundbar is decent. Although the soundstage may seem a bit larger than the actual bar, it doesn’t have any tricks that can make it sound wider. However, the focus is good. Voices and footsteps, for example, seem to be coming from a wider area than a precise location.

  • Crosstalk Error 2.15 dB

The LG SP8YA’s stereo dynamics performance is outstanding. The SP8YA is loud and doesn’t compress too much when played at maximum volume. It can be turned up for parties and listening in large spaces.

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

The LG SP8YA has a decent THD performance. At normal volumes, the amount of distortion within acceptable limits, leading to clean and pure audio reproduction. The THD (Total Harmonic Distortion) increases on max volume, especially in the bass to midCon 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 a great center channel, which is fantastic for dialogue. It comes with a dedicated center channel which makes movie dialogue sound clearer and more accurate- this setup is ready to go with 3 speakers and 2 subwoofers. Its frequency response is well-proportioned, too. Voices are typically reproduced accurately, and they have a lot of detail in the mid-range.

  • 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’s surround sound quality is so bad that it can’t play anything in surround mode. Even when it does, the soundstage only has stereo sound with no sound objects like voices or footsteps accurately localized. Surround sound audio makes it seem like the sounds are coming from every direction, rather than just the speakers in front of 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
