LG S90QY Soundbar Review: Is This 5.1.3 Dolby Atmos System Worth Your Living Room?

1. Quick Verdict: Who Should Buy the LG S90QY?

The LG S90QY is for people who want a genuine surround sound experience from a package that takes about an hour to set up and never requires an AV receiver. If you have a medium to large living room, a good TV, and a taste for big cinematic soundtracks, this system gives you something most single-bar solutions cannot: real sound coming from behind you.

It earns its place because of three things. First, the 570 watt, 5.1.3 channel design gives it the headroom to fill a room without strain. Second, the wireless rear speakers deliver true surround effects rather than virtual tricks. Third, the feature list is deep, with eARC, Dolby Vision passthrough, Wi-Fi streaming, and room calibration all included.

It is not for everyone. If you live in a small apartment where neighbors are close, the subwoofer and rear speakers may be more than you need. If you want to hand-pick every speaker and tweak every crossover, a receiver-based setup will serve you better, and our roundup of the best home audio systems covers that route.

The short version

• Best for: Movie lovers, Atmos fans, and anyone upgrading from TV speakers.
• Standout strength: Wide, enveloping surround and strong dialogue clarity.
• Main trade-off: Limited HDMI inputs and a large footprint.

How it fits into a modern living room

Most buyers considering this system are coming from one of two places. Some are upgrading from the tiny speakers built into a thin television, and the jump is dramatic. Others are moving up from an entry-level bar and want to know whether the extra investment is justified. In both cases the deciding factor is usually the rear speakers. Once you have experienced sound from behind you in a movie, it is hard to go back to a front-only presentation.

It also helps that the S90QY avoids the biggest annoyance of traditional surround: a tangle of speaker wire. You get most of the benefit of a multi-speaker room with a fraction of the installation effort, which is a major reason people who would never buy a receiver are comfortable with this system.

2. Design, Build Quality, and What Is in the Box

Unboxing the S90QY feels like opening a small home theater. You get the main soundbar, a wireless subwoofer, two wireless rear speakers, a remote, an HDMI cable, power cords, and mounting accessories. Everything is finished in a dark, matte look that blends into most living rooms without drawing attention.

The main bar

The bar is long, roughly in line with a 55 to 65 inch television, and it is slim enough to sit in front of most TVs without blocking the screen or the infrared sensor. A small display on the front shows volume, input, and sound mode in a clean, readable way. The fabric and metal grille feels sturdy rather than plasticky, which matters in a product that sits in the middle of your room every day.

Because the bar houses up-firing drivers for height effects, it is a little taller than a basic bar. If your TV sits low on a stand, check the clearance before buying. Wall mounting is supported, and the bundled template makes alignment easier than it usually is.

The subwoofer and rear speakers

The subwoofer is a tall, slim cabinet designed to fit beside furniture. It connects wirelessly, so you only need to find an outlet. The rear speakers are compact and also wireless, but note that wireless here means no audio cable. Each rear speaker still needs a power cable, so plan your outlet locations before you commit to a seating layout.

That detail matters. A lot of people assume wireless means placing speakers anywhere, but you will want power outlets near the back of your seating area. A cheap extension cord run along the baseboard solves this for most homes.

Living with it day to day

Design is not only about looks. It is about how a product behaves when you use it every evening. The remote is simple and logically laid out, with dedicated buttons for volume, input, and sound mode. The front display dims after a few seconds so it does not distract during movies. The subwoofer runs quietly when idle, and the rear speakers wake automatically when audio starts.

Build quality feels consistent across all components. Nothing rattles, the grille cloth is tightly fitted, and the cabinets feel dense. That solid feel is part of why bass sounds tight rather than flabby, since resonant cabinets are a common source of muddy low end in cheaper systems.

3. LG S90QY Specs at a Glance

Before we dig into how it sounds, here is a clear snapshot of the features that matter most. Specs never tell the whole story, but they explain why the S90QY behaves the way it does.

The headline number is 570 watts, but what really counts is how those watts are distributed. Each channel has its own amplification, which means dialogue, effects, and bass do not compete for the same power. That is a big reason the S90QY holds composure during loud scenes.

Specifications can change between regions and firmware updates, so always check the current listing before purchase to confirm what is included.

What the numbers mean in real life

A 5.1.3 layout means you effectively get five ear-level channels, one low-frequency channel, and three overhead channels. In practice, that gives the system enough separate voices to place sounds around you, and it lets the processor decide which speaker handles which part of a mix. Watts matter less than distribution, but 570 watts of total power gives you generous headroom, so the system rarely sounds strained at normal listening levels.

Support for IMAX Enhanced and DTS:X is a bonus that many competing bars skip. If your streaming library or disc collection includes content in those formats, the S90QY decodes it natively, which keeps you from having to rely on generic upmixing.

4. Setup and Connectivity: How Easy Is It?

Setup is where many surround soundbars lose points, and it is where the S90QY quietly impresses. Plug in the bar, plug in the subwoofer, plug in both rear speakers, and the system pairs automatically in most cases. A few minutes later you are listening to demo content.

Connecting to your TV

The recommended connection is HDMI eARC. Run the included cable from the soundbar to your TV’s eARC port, turn on HDMI-CEC, and your TV remote will control volume. This is the only way to pass Dolby Atmos from your TV’s built-in apps to the bar in full quality. If you are unsure which port to use, our walkthrough on how to connect a receiver to a TV explains the eARC concept in plain language, and the same logic applies here.

Wireless and network connectivity

Wi-Fi support is a real advantage. You can stream from Chromecast, AirPlay 2, Spotify Connect, and similar services directly to the bar without involving your TV. Bluetooth is available as a fallback for quick phone playback, though Wi-Fi sounds better for music.

Placement tips

• Place the rear speakers slightly behind and to the side of your main seat, at or just above ear level.
• Keep the subwoofer within reasonable range of the bar, ideally near a wall or corner for stronger bass.
• Avoid hiding the bar inside a cabinet, because the up-firing drivers need open space above them.

If you want to go deeper into general room layout principles, our guide on how to set up a home audio system offers tips that carry over to soundbar setups.

First-time setup walkthrough

Start by placing the soundbar below your TV and connecting the HDMI cable to the eARC port. Power on the TV and the bar, then confirm that the TV’s audio output is set to the external device. Next, place the subwoofer and rear speakers and plug them in. Wait for the indicator lights to confirm pairing, then open the LG Soundbar app on your phone to connect to Wi-Fi and run the room calibration.

Most people complete this in under thirty minutes. The slowest part is usually routing the rear speaker power cables neatly. If you are renting, adhesive cable clips along the baseboard keep things tidy without damaging walls.

Troubleshooting common issues

If you hear no sound from the rear speakers, check that they are powered on and that their volume is not zeroed in the app. If Atmos does not light up, confirm that your TV app is set to output bitstream audio over eARC rather than PCM. A firmware update resolves many odd behaviors, so run one early.

Do you need a subwoofer or rear speaker placement trick?

If you cannot place the rear speakers at ideal positions, aim for symmetry. Equal distance from the main seat on each side matters more than perfect height. The calibration process compensates for modest differences, but it cannot fix a speaker that is blocked behind furniture. Keep sight lines open where possible, and you will get cleaner, more precise surround effects.

5. Dolby Atmos and Surround Performance

This is the section that decides whether the S90QY is worth its place in your home. Dolby Atmos is meant to add height to a soundtrack, so rain falls above you and helicopters pass overhead. A soundbar with up-firing drivers bounces sound off your ceiling to simulate that effect. If you are new to the format, our explainer on what Dolby Atmos means covers the fundamentals.

With the S90QY, the height effect is noticeable and believable, particularly in rooms with standard eight foot flat ceilings. The three height channels give a more convincing dome of sound than bars that only have two. Add the rear speakers, and the experience moves from impressive for a soundbar to genuinely immersive.

Why the rear speakers matter

Rear channels are the difference between sound in front of you and sound around you. When a spaceship flies from the screen toward the back of the room, a bar-only system must fake it with processing. The S90QY actually sends the audio to physical speakers behind you. That produces clearer separation and a stronger sense of space during action scenes.

Ceiling considerations

Atmos from up-firing speakers depends heavily on your ceiling. Flat, reflective ceilings work best. Vaulted, sloped, or very high ceilings reduce the effect. Acoustic tile or heavy textures can also soften it. If your room has a tricky ceiling, the system will still sound good, but you will get less benefit from the height channels.

Understanding the channel layout

The 5.1.3 label can be confusing. The first number is the ear-level channels, the second is the subwoofer, and the third is the height channels. For a deeper look at how these numbers work, our receiver channels explained article breaks it down simply.

What it feels like in a real scene

Think about a rainstorm scene in a film. With a basic soundbar, rain sounds like a hiss from the front. With the S90QY, the rain gains a sense of space above and around you, and thunder rolls across the room. In sci-fi, ships pass overhead, and in war films, bullets whiz past from different directions. These details do not just add spectacle. They add realism, and they pull you deeper into a story.

It is worth being honest about limits. A soundbar cannot reproduce the precision of a ceiling-mounted speaker array, and listeners with larger rooms or very high ceilings may find the height effect subtler. But for typical living rooms, the effect is clearly audible and enjoyable, and it makes a bigger difference than most people expect.

6. Dialogue Clarity and Movie Performance

If a soundbar cannot make speech clear, nothing else matters. This is where the S90QY justifies its dedicated center channel. Voices come out focused and anchored to the screen, even at lower volumes, which is great for late-night viewing.

Action movies

Big blockbusters are the system’s natural habitat. Explosions hit with weight thanks to the subwoofer, and the rear speakers add depth during chaotic scenes. Importantly, the bar keeps dialogue intact while effects pile up, a common weak point in cheaper systems. You will not find yourself reaching for the remote every time the music swells.

Dramas and dialogue-heavy content

Quiet scenes reveal how natural a system sounds. The S90QY avoids the hollow, boxed-in character that plagues many soundbars. Voices sound warm and clear, with a pleasing balance between chest weight and crisp consonants. Adaptive Sound Control can adjust the sound mode based on the content, which is handy for casual viewing.

Streaming and TV shows

Netflix, Disney+, and other streaming services deliver Atmos content in compressed form, but the S90QY decodes it well. Even standard stereo content gets enhanced through the AI Sound Pro mode, which upmixes to take advantage of all speakers.

For comparison, lighter-weight options like the Sony HT-S2000 offer a taste of Atmos in a more compact package, but they cannot match the surround separation of a full 5.1.3 system.

Night listening and volume control

One underrated strength is how the system behaves at low volume. Many soundbars lose bass and clarity when turned down, which forces you to choose between waking the household and understanding the dialogue. The S90QY includes night-friendly options that compress dynamics so whispers remain intelligible and explosions stay civilized. If you often watch after the kids are asleep, you will appreciate that.

Sports and live broadcasts

Live sports are an easy way to test a soundbar. Crowd noise should feel like it surrounds you, while the commentary stays clear and centered. The S90QY handles this well in Sports mode, which lifts speech slightly and spreads ambience wide. Watching a big match or a race on this system feels noticeably more like being in the stadium than watching through TV speakers ever could.

Streaming news and talk shows also benefit from the center channel, since voices remain consistent whether you sit directly in front or off to the side. That consistency makes it a good fit for families who rarely sit in the same spot twice.

7. Music Performance: Is It Good for Listening?

Many soundbars are movie machines first and music players second. The S90QY leans toward cinema, but it handles music respectably. LG partners with Meridian Audio on tuning, and you can hear it in the smooth midrange and controlled treble.

Stereo and Hi-Res playback

Switch to the dedicated Music mode and the system relaxes into a more balanced presentation. Vocals sit front and center, acoustic instruments sound natural, and the subwoofer supports rather than overwhelms. Streaming over Wi-Fi at higher quality noticeably improves detail compared with Bluetooth.

Bass behavior

Bass is deep and punchy but can be boomy in small rooms. The app lets you reduce the subwoofer level, and the Bass Blast mode provides a more aggressive low end if you want it. Electronic and hip-hop tracks sound energetic, while jazz and classical material stay clean at moderate levels.

Where it falls short for audiophiles

If music is your priority, a dedicated stereo system will outperform it. Our guide to the best home stereo system under $500 shows how much music performance you can buy for modest money. For critical listening, pairing quality speakers with a receiver is still the stronger path, and our best home audio receiver list is a good starting point.

For casual playlists, background music, and weekend entertaining, the S90QY is more than good enough. Many owners use it as their everyday music system without complaint.

Choosing the right mode for music

Stick with Music mode for most listening, and try Standard if you find the presentation too spacious. If you stream over Wi-Fi, experiment with the equalizer to match your room. Smaller rooms often benefit from a slight bass trim, while larger rooms can handle the default balance. With a little tuning, the system becomes a surprisingly capable everyday speaker for podcasts, playlists, and background listening.

8. Gaming and HDMI Features

Gamers have different priorities than movie watchers: low latency, passthrough support, and positional audio. The S90QY includes a dedicated Game mode that tunes the sound for effects and directionality. With the rear speakers active, footsteps and gunfire have a convincing sense of position that gives you a competitive edge in shooters and a richer atmosphere in story-driven titles.

HDMI passthrough

The soundbar offers one HDMI input with passthrough alongside the eARC output. That is useful if you want to plug a console directly into the bar, though it also means you only get one extra source. If you own multiple devices, you will likely connect most of them to the TV and rely on eARC to send audio to the bar. Always confirm the latest supported passthrough resolutions and refresh rates on the current spec sheet, since HDMI details vary and can be updated.

Practical gaming tips

• Enable Game mode on both the TV and the soundbar to minimize lag.
• Use eARC for the lowest complexity and best Atmos support.
• Check the sync setting if you notice any audio delay.

For hardcore players with multiple consoles, a receiver gives more inputs, a point we explore in our comparison of best home theater system under $10,000 options that scale far beyond soundbars.

Competitive versus cinematic gaming

For fast shooters, directional accuracy and low delay matter most, and Game mode sharpens effects so footsteps and reloads are easy to locate. For cinematic adventure titles, Cinema mode or Standard with Atmos enabled brings out the score and ambience. Switching between the two is easy through the remote or the app, so you can match the mode to the game.

9. Smart Features, App Control, and Room Calibration

Smart features are where the S90QY separates itself from basic soundbars. It is a connected device, not just a speaker. With Wi-Fi, you get firmware updates, multi-service streaming, and app control.

Streaming support

You can cast audio using Chromecast built-in, AirPlay 2 for Apple devices, and Spotify Connect. This means you can start a song on your phone and let the bar handle playback independently, saving your phone battery and delivering better audio quality than Bluetooth.

AI Room Calibration Pro

The built-in microphone measures how sound behaves in your room and adjusts levels, delays, and tuning accordingly. It is the same idea behind more advanced systems, and our article on how to calibrate receiver speakers explains why this matters. Running it once after placement produces noticeably better balance, particularly with rear speaker distances and subwoofer integration.

Sound modes and the app

The LG Soundbar app gives you control over equalizer settings, sound modes, rear speaker volume, and firmware updates. Modes include Standard, Music, Cinema, Sports, Game, and Adaptive Sound Control. Most people will settle on one or two, but it is nice to have the flexibility.

Voice assistants

Voice control is available through compatible smart devices, though the soundbar’s strengths lie in audio, not in being a full smart speaker. If voice control is a priority, take a look at our Amazon Echo Studio review for a different approach.

Everyday convenience

Small touches add up. The bar remembers your preferred settings per input, wakes automatically when the TV turns on, and installs firmware updates through the app. Multi-room streaming through Chromecast and AirPlay also lets you send the same music to other compatible speakers around the house, which is handy for parties or when you want continuous audio while moving between rooms.

10. Pairing the S90QY With an LG TV

LG designed the S90QY to work especially well with its own televisions, and the pairing unlocks extra features. The most notable is WOW Orchestra, which lets the TV’s built-in speakers work together with the soundbar to add additional channels. Instead of replacing the TV audio, the two cooperate.

WOW Interface and WOW Orchestra

The WOW Interface places soundbar controls inside your TV’s menus, so you can adjust sound settings without picking up another remote. WOW Orchestra then blends the TV drivers with the bar for a wider, taller soundstage. The result is more spacious, and dialogue can feel even more anchored to the screen.

WOWCAST wireless connection

With compatible LG TVs, WOWCAST enables a wireless audio connection between the TV and soundbar. It reduces cable clutter and simplifies setup. You still get the best flexibility with HDMI eARC, but wireless is a nice option for cleaner installations.

Using it with non-LG TVs

You do not need an LG TV. The S90QY works well with Samsung, Sony, TCL, Hisense, and other brands through eARC. You simply lose the LG-specific extras. The core performance, including Atmos and room calibration, stays the same.

If you are weighing it against rivals aimed at other TV brands, our reviews of the Samsung B-Series soundbar and Bose Smart Soundbar provide useful context.

Is the pairing worth it?

If you already own a compatible LG TV, the extra integration is a genuine bonus, and it is one of the few ecosystem advantages in the soundbar world that actually improves sound rather than just convenience. If you do not, you are not missing core performance, only some added polish. In other words, the LG pairing is a perk, not a requirement.

11. Pros, Cons, and Common Complaints

No product is perfect, and the S90QY is no exception. Here is a balanced look at what you gain and what you give up.

Common owner complaints

The most frequently mentioned issues are practical rather than sonic. People wish for more HDMI inputs, find the rear speaker power requirement annoying, and sometimes need a firmware update to resolve occasional connection quirks. Keeping the software current helps, and the app makes it easy.

Another recurring comment is that the bass is strong out of the box. If you have thin walls or close neighbors, reduce the subwoofer level in the app and use the night mode for late viewing.

Who should avoid it

If your room is tiny, if you rent a space with thin walls, or if you only watch casual TV with little interest in surround effects, you can save money with a simpler bar. If you want to expand later with new speakers and a receiver, a component system makes more sense. The S90QY shines when you want a complete solution that works right away.

12. LG S90QY vs the Competition: Alternatives Compared

The S90QY competes in a crowded premium soundbar space. Whether it is the right pick depends on your room size, budget, and priorities. Here is how it compares to several popular alternatives.

When to pick a rival

Choose the Sonos Beam Gen 2 if your room is small and you want a simpler, more compact system. Choose the JBL Bar 1000 if you want even more channels and a larger soundstage. Choose a budget option like the Vizio if you want surround on a tighter budget, understanding that performance will be more modest. For a very compact, entry-level path, the Sonos Ray is another interesting option.

When the S90QY wins

The LG shines when you want the full package at once: Atmos height, wireless rear speakers, strong dialogue, and Wi-Fi smarts. It strikes a smart balance between simplicity and performance, which is why it remains popular with buyers who want real surround without becoming hobbyists.

Soundbar or full home theater?

The biggest comparison is not another soundbar but a traditional receiver-based system. A component setup gives you more power, more inputs, and the freedom to upgrade individual pieces over time, but it demands more space, more wiring, and more learning. The S90QY gives up some of that flexibility in exchange for convenience and a clean look. For many households, that is exactly the right trade.

Conclusion: Is the LG S90QY Worth Buying?

For anyone craving big, cinematic sound without the complexity of a full receiver setup, the LG S90QY is an excellent choice. It delivers real surround thanks to its included rear speakers, impressive Dolby Atmos height effects, clear dialogue, and a feature set that includes Wi-Fi streaming, AI room calibration, and strong HDMI passthrough support.

The trade-offs are manageable. You will want to plan for power outlets near the rear speakers, make sure your TV stand has room, and accept that music playback is very good rather than reference-grade. If you can live with those points, you get a polished, powerful system that makes everyday TV and movies far more exciting.

If you want a compact alternative, look at the Sonos Beam Gen 2. If you want bigger, look at the JBL Bar 1000. But if you want a balanced, immersive package that just works, the S90QY remains hard to beat.

Final buying advice

Before you buy, measure your TV stand, confirm that your TV has an eARC-capable HDMI port, and identify where the rear speakers will sit relative to power outlets. Those three checks prevent nearly every disappointment. Once the system is in place, run the room calibration, set the rear and subwoofer levels to taste, and give yourself a few days to adjust. Many listeners find the system gets better the more they fine-tune it.

Prices change often, so check the current listing before deciding, and compare it with the alternatives above if your budget or room size points elsewhere. With the right expectations, the S90QY is a rewarding upgrade that turns an ordinary TV into the centerpiece of a real home theater.
