The LG S75Q is a 3.1.2 setup released in 2022. It's one of the manufacturer's high-end models for the year with Dolby Atmos support, alongside the LG S80QY and the LG S90QY. It uses built-in Meridian Technology to improve audio reproduction, and you can connect it to compatible LG TVs for TV Sound Mode Share. However, it only has two up-firing Atmos drivers compared to the 3.1.3 S80QY and the 5.1.3 S90QY, and it doesn't offer more premium features like AI Room Calibration to optimize the bar's sound based on your room's acoustics.

Our Verdict

7.3 Mixed Usage

The LG S75Q is decent for mixed usage. It's a pretty versatile bar with Dolby Atmos support, though its height performance is just okay overall. Out-of-the-box, it reproduces pretty clear and accurate dialogue, and its discrete center channel enhances the quality of voices in TV shows. It lacks low bass, though, so you don't feel the rumble in bass-heavy music or action-heavy movies. Surround sound isn't the best, either.

Pros
  • Dolby Atmos support.
Cons
  • Some compression at max volume.
7.6 Dialogue/TV Shows

The LG S75Q is good for dialogue-centric content like TV shows. It's a 3.1.2 setup, so it has a discrete center channel that helps reproduce dialogue clearly and accurately. You can use its 'Clear Voice' dialogue enhancement feature if you want, and there's also a Night Mode feature to balance out the volume level when you watch shows at night. Out-of-the-box, its balanced mid-range means voices are clear in the mix, though they're also a bit dark due to the recessed treble.

Pros
  • Good center channel performance.
  • Dialogue enhancement feature.
Cons
  • Some compression at max volume.
7.2 Music

The LG S75Q is decent for music. Out-of-the-box, it has balanced mids that reproduce clear and accurate voices and lead instruments. There's a little extra boom in the high bass, and its recessed treble adds a slight darkness to the sound. You have lots of customization features on hand, including bass and treble adjustments and EQ presets. It can't reproduce the deep thump and rumble in the low-bass found with bass-heavy music like hip-hop and EDM.

Pros
  • Bass and treble adjustments.
  • EQ presets.
Cons
  • Some compression at max volume.
  • Lacks low-bass.
7.1 Movies

The LG S75Q is decent for movies. It supports Dolby Atmos content, which is often found on streaming services. The bar's height performance is decent, but it doesn't provide the same immersive experience as more premium models. There's also support for surround sound like Dolby Digital and DTS, though it has to downmix this content into stereo in order to play it. Its lack of low-bass means that you don't feel the deep rumble in action-packed scenes.

Pros
  • Bass and treble adjustments.
  • Dolby Atmos support.
Cons
  • Some compression at max volume.
  • Lacks low-bass.
  • 7.3 Mixed Usage
  • 7.6 Dialogue/TV Shows

Differences Between Sizes And Variants

The LG S75Q is available in 'Black', and the label for our model is here.

If you come across another version of this soundbar, let us know in the discussions.

Compared To Other Soundbars

The LG S75Q is a 3.1.2 setup with Dolby Atmos support. It's a fairly versatile bar, but it's best suited for listening to dialogue-centric content like TV shows and podcasts. It lacks low-bass, and its surround sound isn't that great on its own, especially compared to more premium setups like the LG S90QY.

See also our recommendations for the best soundbars, the best Dolby Atmos soundbars, and the best LG soundbars.

LG S80QY

The LG S80QY is better than the LG S75Q for most uses. The S80QY comes with more sound enhancement features, like room correction, as well as more wireless playback options. It can also reproduce a more extended low-bass, so you feel more thump and rumble in your audio. The S75Q also supports Dolby Atmos content, and it's a more affordable alternative.

LG SP8YA

The LG SP8YA is better than the LG S75Q. The SP8YA is a 3.1.2 setup that reproduces a more extended low-bass, so you feel more thump and rumble in your audio. It comes with more sound enhancement features, like room correction, and it supports more wireless playback options.

LG S65Q

The LG S75Q is better than the LG S65Q. The S75Q is a 3.1.2 setup, and it supports Dolby Atmos content found on lots of streaming platforms, unlike the S65Q. The 3.1 S65Q is still a solid pick for you if you just watch TV shows and music.

Samsung HW-Q600C/Q60CC

The Samsung HW-Q600C/Q60CC and the LG S75Q are both 3.1.2 soundbars, and the Samsung is better overall. The Samsung can reproduce more low-bass, so you feel more rumble in the mix. Plus, it has a better performance on its height channels with Dolby Atmos content. There are some more sound customization tools, like a graphic EQ.

Sonos Arc

The Sonos Arc is better than the LG S75Q. The Sonos is a 5.0.2 standalone bar with a premium design. It has better soundstage, surround, and Atmos performances and supports more premium features like room correction. While the LG comes with a dedicated sub, it doesn't reproduce as much low-bass compared to the Sonos.

LG SC9S

The LG SC9S is better than the LG S75Q. The SC9S comes with more features, including a room correction tool to calibrate its sound based on your room's acoustics, as well as Wi-Fi, Chromecast, and Apple AirPlay capabilities. It has a better stereo soundstage, too, and it has a better low-frequency extension to bring more thump and rumble to the mix. Plus, there's an additional up-firing center channel, designed to improve vocal reproduction in the mix.

Sonos Beam (Gen 2)

The Sonos Beam (Gen 2) is a small, standalone soundbar with a slightly different design than the LG S75Q. The Sonos is more versatile overall, as it's a 5.0 setup with better soundstage and surround performances. That said, the LG comes with a dedicated sub and reproduces more low-bass than the Sonos. You can add a sub to the Sonos if you want, though.

LG S75QR

The LG S75QR is better than the LG S75Q. They're the same bar and sub, but the S75QR adds rear speakers for an improved surround sound. You notice a more clear and real feel with content like Dolby Digital and Dolby Atmos, which are common on streaming platforms and Blu-rays.

LG S77S

The LG S77S is a Costco-exclusive alternative to the LG S75Q. The S77S has a different design with more rounded edges that may appeal to some users over others. Its sound performance is pretty similar, though its soundstage isn't quite as good with stereo content. On the upside, the S77S adds more video passthrough support, including for 4k content at 120Hz.

LG SP7Y

Depending on your listening habits, you may prefer either the LG SP7Y or the LG S75Q. The SP7Y is a 5.1 setup with better soundstage and surround performances. However, it doesn't support Dolby Atmos content like the 3.1.2 S75Q. If you watch a lot of surround content, the SP7Y is better, but you can always add rear speakers to the S75Q if you want Atmos support.

LG SG10TY

The LG SG10TY has the edge over the LG S75Q, though the largest differences come down to size. The SG10TY is a 3.1 soundbar, which is meant to be mounted onto the wall. It can get louder with fewer compression artifacts, ensuring your audio sounds clear, even at high volumes. There are also more customization features available to help you make the most out of the bar. It also supports more wireless connectivity options like Wi-Fi. That said, you may still prefer the better-built S57Q if you're low on space since it's a lot smaller. 

Samsung HW-Q800A

The Samsung HW-Q800A is better than the LG S75Q. They're both 3.1.2 bars with Dolby Atmos support, but the Samsung is able to reproduce a more extended low-bass, so you feel more thump and rumble in bass-heavy music and movies. It has a better soundstage, too. 

Samsung HW-Q60B

The Samsung HW-Q60B is better than the LG S75Q for most uses. The Samsung is a 3.1 setup, and it has a more neutral sound out-of-the-box, especially in the treble range. As a result, higher-pitched sounds like cymbals are more detailed in the mix. It has a graphic EQ for customization, too. However, the LG's better for Dolby Atmos content since it offers up-firing height drivers, while the Samsung's advertised up-firing drivers aren't for height content.

Bowers & Wilkins Panorama 3

The LG S75Q is a better 3.1.2 setup than the Bowers & Wilkins Panorama 3. These bars have slightly different designs, as the LG comes with a dedicated subwoofer, whereas the B&W's sub is integrated into the bar. The LG reproduces a more extended low-bass, and it also has a better soundstage. There are also more sound enhancement features on hand.

Design
Style - Bar

The LG S75Q is a simple soundbar with a similar design to the LG SP8YA. It's mostly plastic, and there are two metal grilles on top of the bar where the up-firing drivers are located. While the SP8YA has rounded corners, the S75Q's corners are square.

This setup doesn't come with satellites. We purchased the SPQ8-S Rear Speaker Kit separately, but when we tried to connect it to the bar, it didn't work. It doesn't seem to be an issue with the speakers themselves, as they connected to the LG S80QY without issue. If you've tried this setup yourself, we'd love to hear about your experience in the discussion section below.

The LG S75Q is fairly wide, and it likely won't fit between the legs of a 55" TV stand. That said, it's not very tall, so it doesn't obscure your TV screen.

Build Quality

The LG S75Q has a good build quality and feels more sturdy than the sleek, wall-mountable LG SG10TY. The bar is mostly plastic, which feels solid and durable. The sub is also plastic. There's fabric on the front, and it's tight, so it isn't likely to rip. It can collect dust over time, though.

The LG S75Q has a decent stereo frequency response out-of-the-box. It has a fairly balanced mid-range that reproduces clear vocals and lead instruments. The treble range is slightly recessed, so instruments are pushed towards the back of the mix with certain tracks. It doesn't reproduce a lot of low-bass, either, especially compared to other 3.1.2 Atmos models like the Samsung HW-Q600C/Q60CC, so you don't feel as much thump in bass-heavy music.

With its bass set to '0' and its treble set to '5', the LG S75Q has a satisfactory stereo frequency response. It has a more neutral, balanced sound profile with balanced mid and treble ranges, so voices and lead instruments are clear and detailed. That said, bass adjustment features can't make up for the lack of low-bass, so you still don't feel the rumble in bass-heavy genres like EDM.

Stereo Soundstage

The LG S75Q has a decent stereo soundstage. The soundstage is perceived to be a touch wider than the bar, but it doesn't have any tricks to make it seem wider than that. The focus is decent, and sound effects seem to come from a more general area as opposed to an accurate, pinpoint location.

The LG S75Q has a great stereo dynamics performance. The bar gets loud, filling up larger, open living rooms with sound. Updating the bar to firmware version B230411A improved its performance quite a bit, especially regarding compression. There's a bit when the bar is pushed to max volume, but it's not very noticeable.

The LG S75Q has a decent stereo THD performance. At a normal listening volume, distortion falls within good limits, so audio reproduction is clean and pure. There's a jump in distortion at max volume, which audiophiles are more likely to notice. That said, casual listeners who rarely crank up the volume aren't likely to notice any issues.

The LG S75Q has a good center channel performance. With its discrete center channel, dialogue reproduces with clarity and accuracy, and voices are localized to pinpoint locations within the soundstage. Its frequency response on this channel is quite balanced in the mids, so voices are clear, but the dip in the mid-treble means they lack some detail.

The LG S75Q has a poor surrounds performance. It's a 3.1.2 setup, so it has to downmix surround sound into stereo to play it. As a result, it doesn't seem like the action is taking place all around youโ€”it just seems like your movie is playing from a speaker in front of you. The LG S75QR has satellite speakers, offering better performance with surround sound.

The LG S75Q has two up-firing drivers built into the bar to simulate height with Atmos content. The frequency response of these channels is quite uneven, though, especially in the low-mids and the treble. Some details are less clear in the mix as a result. Also, we subjectively evaluated the bar's Atmos performance to get a sense of its overall soundstage and immersive feel. The results were okay, but nothing special. Most of the sound seems like it's coming from the space in front of you, but it doesn't do much to spread the effects to the space around you, which is typical for a bar without satellites. You don't notice a lot of height, either, or sound behind your couch.

The LG S75Q has a satisfactory selection of sound enhancement features. You can customize its sound using features like its bass and treble adjustments or its EQ presets: 'Standard', 'Bass Blast', 'AI Sound Pro', 'Cinema', 'Sports', 'Game', 'Clear Voice', and 'Music'. The 'Cinema' preset doubles as a virtual surround mode that creates a more three-dimensional sound, and the 'Clear Voice' preset enhances dialogue. If you choose to add on rear satellites, you can adjust the rear levels. Most of these features are accessible in the LG Sound Bar app. Unlike the Samsung HW-Q60B, there's no graphic EQ available, though, and you won't find a room correction mode unless you upgrade to the LG S80QY.

Like many other soundbar manufacturers, LG offers a feature that lets you pair the bar with compatible LG TVs - it's called TV Sound Mode Share. Check your TV's Sound Menu to make sure you're in 'Enjoy Soundbar Sound Mode' instead of 'Enjoy TV Sound Mode' to get the feature to work - otherwise, it might downmix higher-quality formats like Dolby Atmos into PCM content. The manufacturer says that this feature enhances the sound quality, but like most of these features, there isn't much of a difference in the sound with it turned on.
