The Sonos Arc Ultra is the best soundbar for an LG TV overall in 2026. It decodes 9.1.4-channel Dolby Atmos, sets up over a single HDMI eARC cable, and earns the highest owner rating in our comparison at 4.6 stars from 721 reviews. Every pick below was checked against LG-specific issues: eARC support, HDMI input scarcity, WOW Orchestra pairing, and dialogue clarity.
LG TVs are thin by design, and the speakers bolted to a 65-inch or 77-inch panel cannot produce real bass or a soundstage that reaches past the couch. Almost any soundbar is a meaningful upgrade, but the wrong one wastes your money: bars that lack a proper eARC path, sit too tall and block the IR sensor, or force you into an app that fights you at every step.
We compared eight soundbars against the things LG owners actually complain about. The line-up spans the flagship LG S95TR and S90TR, the compact S70TY and the 4.1-channel S40TR, plus the third-party options that keep showing up in owner threads: the Sonos Arc Ultra, the Polk Audio Signa S4, the ULTIMEA Poseidon M60, and the Bose TV Speaker. If you have not settled on a TV yet, start with our smart TV picks and our broader soundbar roundup first.

1. Sonos Arc Ultra – Best Overall for an LG TV
Sonos Arc Ultra Soundbar with Dolby Atmos – Black
★★★★★★★★★★Channels: 9.1.4
Dolby Atmos
Weight: 12.7 lb
Width: 46.18 inch
- Excellent 9.1.4-channel Atmos with precise height effects
- AI speech enhancement for clear dialogue
- Single-cable HDMI eARC setup
- Trueplay room tuning and night mode
- No physical remote included
- Trueplay results vary with the phone used
- No true surround until you add Sonos rears
The Arc Ultra is the bar we would put under any LG set, flagship or budget, because it makes almost none of the mistakes the LG bars make. It decodes 9.1.4-channel Dolby Atmos, it does not depend on a phone app for basic control, and it takes over volume and power from the TV remote over HDMI-CEC the first time you plug it in.
Dialogue is where it earns its rating. AI-powered Speech Enhancement lifts voices out of the mix without pushing the whole soundtrack louder, which is the exact problem most LG owners describe in the first month with a new OLED. The soundstage is wide enough that a 65-inch C-series and a 77-inch G5 both get filled, and the 3.13-inch-tall body clears the bottom edge of most LG panels.
Reviewers note one integration quirk worth knowing before you unbox it. If you are swapping an older soundbar, the first few days can sound flat until the LG TV is re-paired so it recognises the Arc Ultra as the output device. Unplug the old bar, reconnect the HDMI eARC cable, and let the TV re-scan before you judge the sound.
What to check before you buy the Arc Ultra for an LG TV?
It ships without a physical remote, so plan on controlling it with the LG remote, the Sonos app, or the touch controls on the top of the cabinet. That is not a problem if your LG TV is modern, because HDMI-CEC passes volume, mute and power through cleanly.
Trueplay room tuning measures your room with a phone, and owners report the accuracy shifts depending on which phone you use. Run it with the phone you actually own, and re-run it after you move furniture. The subwoofer is a separate purchase, so budget for the full system rather than the bar alone if you want real low end.
Where the Arc Ultra falls short?
It cannot produce genuine rear separation on its own. Adding Sonos Sub and Era rears turns it into a real surround system, but that is a second and third purchase, and the total cost climbs well past what an LG complete package delivers.
Music playback is described by some owners as good rather than excellent, and there is no included HDMI cable in the box. For a pure film and TV bar on an LG TV, those are acceptable trade-offs. For a system that also has to carry a record player or a turntable, read our 4K TV guide context and weigh the alternatives below.

2. LG S95TR – Best for Full Cinema on a Large LG OLED
LG S95TR 9.1.5 ch Home Theater Soundbar with Dolby Atmos and Rear Speakers
★★★★★★★★★★Channels: 9.1.5
Dolby Atmos and DTS:X
Weight: 34.6 lb
Width: 49.2 inch
- Genuine 9.1.5 Atmos with true wireless rears
- Up-firing center channel sharpens dialogue
- Room calibration with built-in microphone
- VRR and ALLM with 120Hz passthrough
- Setup and tuning depend on the ThinQ app
- Written instructions are thin
- Deep bass needs manual effort to dial in
The S95TR is the most technically complete bar LG ships, and the only one here with 9.1.5 channels driven by genuinely wireless rear speakers plus an 8-inch subwoofer. The carton contains the bar, sub, two rears, a remote, an HDMI cable, batteries and a wall mount bracket, so you are not hunting for accessories after delivery.
What stands out in owner feedback is the up-firing center channel. LG routes dialogue through a dedicated upward-firing driver aimed at the seating position, and on an OLED with a wide panel that keeps voices anchored to the screen instead of drifting across the room. WOW Orchestra and WOWCAST are both built in, so the bar can also work wirelessly with a compatible LG TV.
The 49.2-inch-wide body is the practical catch. On a 48-inch or 55-inch TV it overhangs noticeably, and at 34.6 pounds the whole package is a two-person lift. Room calibration uses a built-in microphone, but the results are not displayed anywhere, so you are trusting the algorithm rather than seeing it.
Gamers get something the other LG bars handle less completely. VRR and ALLM pass through at up to 120Hz, which matters on LG HDMI 2.1 boards where a console competing for bandwidth with 4K 120Hz output is a real negotiation.
Is the S95TR worth the LG app?
Owners who pair this bar with an LG OLED frequently call it a cinematic upgrade for dialogue intelligibility, and the wireless pairing between sub, rears and bar is reported as stable by most reviewers. The recurring complaint is the software layer, not the sound: the ThinQ app fails for some people at the device-add step, and recovery usually means a hard reset.
That friction is worth weighing if you dislike phone-based setup. The written documentation is also thin, so expect to search for a walkthrough before the first evening. If your TV is an LG and you plan to use WOW Orchestra, the app is unavoidable here.
When to skip the S95TR?
Skip it for screens smaller than 65 inches, where the 49.2-inch bar dominates the picture and the extra channels go mostly unused. Owners upgrading from an older component system also describe the sound as good rather than exceptional, so if you have a reference setup already, this is not a step change.
Deep bass is another reason to pass. Because the system leans on automated processing, getting low end to the level you want takes manual effort that many owners skip. The S90TR below covers most of the same ground at a lower channel count and a smaller footprint.

3. LG S90TR – Best Match for an LG C-Series OLED
LG S90TR 7.1.3-Channel OLED evo TV Matching Home Theater Soundbar with Rear Surround Speakers and Wireless Subwoofer, Wow Orchestra, Dolby Atmos, WOWCAST Built-in
★★★★★★★★★★Channels: 7.1.3
Dolby Atmos and DTS:X
Weight: 44.8 lb
Width: 49.2 inch
- Crisp 7.1.3 Atmos with up-firing center for dialogue
- Wireless sub and rears pair quickly
- WOW Orchestra and WOWCAST built in
- Advanced room calibration
- App EQ limited to three blended tone bands
- Calibration shows no read-out
- 49.2 inch body is bulky for smaller screens
The S90TR is the model most C-series owners end up with, and the reason is simple: 7.1.3 channels with wireless rears, a wireless subwoofer, WOW Orchestra and built-in WOWCAST in one package. At 4.5 stars across 118 reviews, satisfaction is high, with 76% of owners handing over five stars.
Dialogue clarity is the recurring theme in positive reviews, credited to the up-firing center channel. Owners pairing a 70-inch to 77-inch TV report a soundstage wide enough to fill the seating area, and the wireless subwoofer and rear satellites are described as pairing quickly without a long troubleshooting session.
Where enthusiast owners push back is tuning flexibility. The equaliser in the app offers blended high, mid and low tone channels rather than a real parametric curve, and the room calibration gives no numbers back, so you cannot tell whether it did anything. A smaller group reports intermittent disconnections that are hard to restore without a full re-pair.
It is also a wide bar. At 49.2 inches it matches the S95TR footprint, so the same screen-size caveat applies, and 44.8 pounds covers the full package including the sub and rears.
How the S90TR pairs with an LG C-series?
WOW Orchestra lets the TV’s own speakers join the soundbar for a taller front stage, and WOW Interface means the TV remote handles soundbar volume and mode selection. Both features depend on a compatible LG TV and a working app setup, so check your model before buying on the strength of the feature.
Multiple international reviews call out the value of the package relative to buying a sub and rears separately. The 49.2-inch width suits a 70-inch or larger screen, and the Smart Up-Mixer converts 2-channel sources into multi-channel output, which helps with broadcast TV and older streaming services.
Where the S90TR disappoints?
If you like to tune by ear with a real equaliser, this is the wrong bar. The three-band app control is the most substantive complaint in the reviews, and the calibration process is a black box rather than a tool. It also passes through VRR and ALLM at up to 120Hz, so keep the console wired rather than routing through an intermediate device.
For a bedroom TV or a 55-inch panel in a small apartment, the flagship S90TR is overbuilt. The S70TY and the Polk Signa S4 below cover those rooms properly.

4. Polk Audio Signa S4 – Best Value Soundbar for an LG TV
Polk Audio Signa S4 Dolby Atmos 3D Sound Bar System with 5.9″ Wireless Sub
★★★★★★★★★★Channels: 3.1.2
Dolby Atmos
Output: 410 watts
Width: 41.2 inch
- 7-driver array with up-firing height drivers
- VoiceAdjust keeps dialogue clear
- 5.9 inch wireless sub adds real bass
- 2.36 inch body clears the TV sensor
- No front display only LED indicators
- No Wi-Fi or streaming apps
- No path to add rear speakers
With 1430 reviews at 4.3 stars, the Signa S4 has the kind of long, settled review history most soundbar buyers never see. It is not an LG product and it does not do WOW Orchestra, but it does two things that matter on an LG TV: it decodes real Dolby Atmos, and its 2.36-inch body will not block the bottom edge of the panel or the infrared sensor.
The array is genuinely seven drivers, including a dedicated full-range center channel and up-firing elevation speakers that use Atmos height channels. Polk VoiceAdjust lifts dialogue without drowning out the rest of the mix, and the 5.9-inch wireless subwoofer adds bass that owners consistently describe as room-filling rather than decorative.
Setup is the easiest in this group. HDMI, optical and USB cables are all in the box, HDMI-CEC gives you TV remote volume control, and Polk rates it as compatible with any TV including 8K sets over a single cable. Nothing to download, nothing to sign into.
The 410-watt figure is peak output rather than a measure of sound quality, but the system has real physical drivers behind it, which is more than most bars at this level offer. The 3.1.2 configuration is honest Atmos: a center channel for speech plus two upward-firing height channels, with no rear separation behind you.
Owners frame it as the best value in the Atmos soundbar-plus-sub category, and 68% of reviews are five stars. A recurring note is that it performs identically on an LG set, a Samsung set or a smaller LED TV, because nothing about it depends on the brand of the panel.
Why the Signa S4 fits an LG TV so well?
The 41.2-inch width is the sweet spot for a 55-inch or 65-inch LG screen, and the 2.36-inch profile sits below most LG bezels without hiding content. The wireless subwoofer means one cable from the bar to the TV and one power lead, which matters in apartments where every socket is contested.
For dialogue-heavy viewing, the dedicated center channel plus VoiceAdjust is the reason this bar keeps coming up in owner recommendations. News, reality television and dense film mixes stay intelligible without turning the whole mix up.
Where the Signa S4 falls short?
There is no Wi-Fi, no AirPlay, no Chromecast and no voice assistant, so Bluetooth is your only wireless streaming path. There is also no expansion route to rear speakers, so if you later want true surround you are replacing the system rather than adding to it.
The front panel has no display, only coloured LED indicators, and a minority of owners report HDMI-ARC handshake cycling where audio drops until a full power reset. The height effect is present but subtle rather than dramatic, and there is no game or sports sound mode. For a music-first household, the tuning leans toward movies.

5. ULTIMEA Poseidon M60 – Budget Pick for Bedrooms and Small Rooms
ULTIMEA 5.1CH Surround Sound Bar System with Dolby Atmos, Poseidon M60
★★★★★★★★★★Channels: 5.1
Dolby Atmos
Output: 300 watts
Width: 31.5 inch
- Real 5.1 channels with side-firing drivers
- VoiceMX keeps voices clear over action
- Wired 5.25 inch sub with tight bass
- App EQ with 10 bands and 121 presets
- Surround is virtual not true rear separation
- Music playback sounds thin
- Subwoofer is wired with an RCA cable
With 2687 reviews at 4.5 stars, the Poseidon M60 has the largest review base in this comparison and 75% five-star ratings. It is the pick when the TV is in a bedroom, a study or a small apartment living room and you want genuine multi-channel output plus a subwoofer from a single carton.
Unlike most budget bars, it has real side-firing drivers rather than a purely simulated surround stage, so 5.1 channels with Dolby Atmos come from six drivers at 300 watts peak. VoiceMX isolates vocals in real time, which is why owners describe dialogue staying easy to follow even during loud action sequences.
The Ultimea app is a genuine advantage here, offering a 10-band graphic equaliser, 121 presets and 13 adjustable surround levels. That is more control than the LG S90TR gives you. Setup takes under a minute over HDMI eARC, and CEC means the TV remote handles power and volume on Roku, TCL and older Sony sets as well as LG.
The subwoofer is a 5.25-inch wooden cabinet with BassMX tuning, connected to the bar by an RCA cable. That wired link is a downgrade from the wireless subs in the LG packages, but it is also more reliable and keeps latency down, and the low end is described as tight and controlled rather than boomy.
Frequency response runs from 45 Hz to 18 kHz with a 99 dB maximum output, and Bluetooth 5.4 handles phone streaming. The enclosure is wood rather than metal, which is unusual at this level and helps avoid the thin, plasticky character owners complain about in entry-level bars.
What you get in a small apartment setup?
The 31.5-inch depth and low profile mean the bar sits in front of the TV without blocking the screen at low viewing angles, and at 12.6 pounds the whole system is easy to reposition. One HDMI cable to the LG TV, one power lead for the bar, one for the sub.
Owners repeatedly describe it as delivering dialogue clarity comparable to far more expensive bars in a bedroom, which is the single most common soundbar complaint from LG OLED owners. Virtual surround bounced off the front walls is a fair description of what you are hearing behind the soundstage, but the width is real.
What to know before buying?
Music playback lacks warmth compared with a dedicated hi-fi system, and the default music equaliser is flat unless you open the app and adjust it. The surround is virtual rather than true rear separation, so do not expect the effect the LG S95TR or S90TR wireless rears produce.
One long-term owner who bought three units reported optical port failures and Bluetooth failures on two of them, though the manufacturer resolved it with an upgrade to a higher-tier model. Bass is good rather than room-shaking, and the subwoofer connection is a cable rather than wireless. If you want a permanent living room system, look at the LG packages instead.

6. Bose TV Speaker – Best for Compact TVs and Secondary Rooms
Bose TV Speaker – Soundbar for TV with Bluetooth and HDMI-ARC Connectivity, All-in-One Compact Soundbar, Includes Remote Control, Black
★★★★★★★★★★Channels: stereo 2.0
Output: 35 watts
Width: 23.38 inch
- Dialogue mode keeps speech clear over music
- Compact 2.21 inch body fits small rooms
- Single-cable optical or HDMI setup
- Adds a Bose Bass Module for low end
- Only 35 watts with attenuated bass
- No HDMI cable in the box
- Sub expansion locked to Bose modules
At 14271 reviews, the Bose TV Speaker has by far the largest owner base in this comparison. That matters, because the pattern is consistent: buyers treat it as the just-works option, especially for a bedroom or secondary TV where the built-in LG speakers are the only alternative.
The 23.38-inch body and 2.21-inch height fit in front of almost any TV, including a 32-inch or 43-inch LG panel, and 4.3 pounds means you can move it between rooms yourself. Two angled full-range drivers deliver wider sound than the enclosure suggests, and dialogue mode reliably keeps speech clear over background music.
Setup is a single optical or HDMI cable, and HDMI-CEC means the LG remote handles volume and power. Owners report getting it running within minutes, including on older sets. If your LG TV predates HDMI ARC, note that you need an extractor dongle first.
This is not a Dolby Atmos bar. It is a stereo system with an optical or HDMI-ARC input, so there is no height channel, no object-based audio and no surround processing to speak of. What it fixes reliably is the thin, tinny quality of small TV speakers, particularly on speech.
At 35 watts the ceiling is low, and the bass is deliberately attenuated so the unit stays coherent at lower volumes. That restraint is exactly right for a bedroom at night and exactly wrong for a 77-inch OLED in an open-plan living room.
When the Bose TV Speaker is the right answer?
This is the bar to buy when the screen is 43 inches or smaller, the room is small, and you watch news, talk shows and streaming series more than you watch action films. Dialogue mode is the primary buying reason for most owners, and it is the feature that actually delivers.
It also works as a second system for a kitchen or office TV, and the compact body mounts to a wall or sits on a narrow shelf. Our TV stand picks cover furniture that leaves room for a bar this shallow.
What you give up with a Bose TV Speaker?
The 35-watt output is the headline limitation, and the 8% of reviews that are one star concentrate on value and on locked subwoofer expansion. Bass is only available through the Bose Bass Module 500 or 700, and third-party subs rarely work with it.
Other small annoyances: no HDMI cable is bundled, the power cable is short and enters at the back rather than the centre, the only feedback is a single small LED with no menu, and the remote takes a coin cell battery. Bluetooth is version 4.2, which is old. It remains the easiest way to fix thin TV dialogue, but it is not a cinematic upgrade.

7. LG S70TY – Best for LG QNED Sets and Mid-Size Screens
LG S70TY 3.1.1 ch QNED TV Matching Soundbar with Wireless Subwoofer – Black
★★★★★★★★★★Channels: 3.1.1
Dolby Atmos
Weight: 8.7 kg
Width: 37.4 inch
- Compact 37.4 inch width suits mid-size LG TVs
- Up-firing center channel for voice
- WOW Orchestra and WOW Interface
- 4K 120Hz passthrough for consoles
- No display only LED indicators
- WOW Orchestra drops out for some owners
- Bass slightly light against mids and treble
The S70TY is the LG bar for anyone who does not want a 49-inch flagship in the room. At 37.4 inches wide it nests neatly under a QNED or a mid-size C-series OLED without overhanging the panel, which is the single most common reason owners recommend it.
Underneath you get 3.1.1 channels with an up-firing center channel for voice, Dolby Atmos decoding, a wireless subwoofer, and both WOW Orchestra and WOW Interface for one-remote control with an LG TV. Dolby Atmos plus 4K 120Hz passthrough means a single cable also carries a console signal. Owners rate the bass as plentiful for the class, and 71% give five stars.
Reviews also recommend a specific TV setting: switch off AI Sound and use Cinema mode, then turn on Auto Volume. Several owners say that single change removes most of the complaints about the sound profile, and it costs nothing to try before you return the bar.
Expansion is possible but awkward. The bar supports LG 2.0-channel wireless rear speakers, and owners report that the SPT8-S kit is hard to source in the US, so treat rears as a bonus rather than a plan.
How the S70TY behaves with an LG QNED or C-series?
WOW Orchestra is the reason to stay in-brand here, and it works best when the TV is a supported model and the app connection holds. WOW Interface also lets the TV remote change sound modes, so you are not juggling a second remote for everyday use.
The Smart Up-Mixer converts 2-channel broadcast audio into multi-channel output, which makes daytime television noticeably better than the TV speakers alone. VRR and ALLM pass through at up to 120Hz, so a PS5 or Xbox on an LG HDMI 2.1 board gets a clean signal.
Known problems to plan around
There is no front display, only LED indicators, and some owners needed LG support to confirm that behaviour was normal. More seriously, installation can fail to hand over TV remote volume control if other HDMI devices are already connected, so plug the soundbar in first, confirm control, then add your console and streaming devices.
WOW Orchestra repeatedly disconnects for a subset of owners and needs a full reinstall, and the bar has no standalone Wi-Fi or Ethernet, so there is no direct media-server casting. Bass is slightly light compared with the midrange and treble. None of these are fatal, but they are worth knowing before you commit.

8. LG S40TR – Best Complete 4.1-Channel Package on a Budget
LG S40TR 4.1 ch. Home Theater Soundbar with Rear Surround Speakers and Wireless Subwoofer, Wow Interface, Dolby Audio, AI Sound Pro, Amazon Exclusive – Black
★★★★★★★★★★Channels: 4.1
Dolby Audio
Weight: 12.9 lb
Width: 28.4 inch
- Sub plus two rear speakers in one package
- Clear Voice Plus for conversation
- Smart Up-Mixer widens stereo sources
- App EQ with 3 bands
- No mounting points on the bar itself
- Rear speakers stay silent until enabled in the app
- No display so settings need the app
The S40TR is the most complete package per box in this comparison. You get a 4.1-channel bar, a wireless subwoofer and two wireless rear surround speakers, with 640 reviews at 4.3 stars behind it. For a 55-inch LG TV in a bedroom or a smaller living room, that is a lot of hardware for the money.
Clear Voice Plus improves conversation intelligibility in films and shows, and the Smart Up-Mixer widens the soundstage by converting 2-channel audio into multi-channel output, which is a real upgrade for broadcast TV. Cinema mode is widely recommended by owners and delivers punchier results than the default profile.
The rear satellites create a convincing surround effect from the optimal centre seating position, with sound tracking between them. A detailed owner review in this set argues the system delivers genuine object movement provided you sit between the rears, which is worth remembering before you place the speakers.
Setup has three gotchas that catch nearly everyone. The rear speakers produce no sound until you enable them in the LG Soundbar app. They each need their own power outlet, which the instructions do not mention. And the two rears are joined by a short speaker wire, so the system is not fully wireless behind the bar.
There is also no mounting point on the bar itself, so it cannot be wall-mounted even though brackets appear in related packages. At 28.4 inches wide and 2.5 inches tall it is compact, and 12.9 pounds covers the bar alone rather than the full set.
What the S40TR does well with an LG TV?
WOW Orchestra and WOW Interface let the TV remote run the soundbar and the TV together, and the LG Soundbar app offers three-band equaliser control for bass, treble and midrange. That is enough to correct a bright room without a measurement microphone.
Because the rears are separate boxes, you can place them behind the seating rather than bouncing sound off a wall. That is the difference between this package and the virtual surround in cheaper single-bar systems, and it is why it suits a rectangular living room.
Where the S40TR falls short?
Control friction is the dominant theme. Owners report the app periodically reporting no soundbar connected, audio occasionally lagging behind picture, and the absence of any display on the bar meaning remote changes are invisible until you check the phone. Dolby Audio is supported but this is not a full Atmos decoder with height channels.
Some owners also consider it simply a louder version of TV speakers rather than a theatre experience, which is fair if your main content is dialogue. If you want a genuine cinematic soundstage with height effects, the S90TR is the step up.

WOW Orchestra Explained: Which LG TVs and Soundbars Pair Up?
WOW Orchestra is the feature that makes an LG soundbar an LG soundbar. Instead of muting the TV’s speakers when a soundbar takes over, WOW Orchestra lets the TV rejoin the mix, so the panel’s top-firing drivers add height and width to whatever the bar is playing.
It needs two compatible devices: a supported LG TV and a supported LG soundbar. One device alone does nothing. Among the LG bars in this comparison, the S95TR, S90TR, S70TY and S40TR all support WOW Orchestra, while the third-party picks do not.
LG’s current compatibility list covers its 2026 OLED range, including the C-series models in 65-inch, 77-inch and 83-inch, and the G-series in 55-inch, 65-inch, 77-inch, 83-inch and 97-inch sizes. Check your exact model number against LG’s support page before you buy on the strength of the feature, because the list changes with each lineup.
Enabling it is not obvious. Open the LG SoundBar app, tap the settings gear, go to Sound Settings, and switch WOW Orchestra on. Owners report the toggle being buried exactly where people do not look, which is why so many buyers never try it.
Not everyone likes the result. In an r/LGOLED thread titled around the feature being disable-able, owners describe turning WOW Orchestra off because the combined output was worse for them than the soundbar alone, particularly on content where the TV speakers added a delayed or boxy layer. Treat it as an experiment: run a film both ways for ten minutes and keep whichever sounds better.
WOWCAST is different and easier to explain. It sends audio from the TV to a compatible soundbar over Wi-Fi with no visible cable, and it is built into the S95TR and S90TR. WOW Orchestra uses the TV’s speakers; WOWCAST moves audio across the room. You can use either without the other.
How to Connect a Soundbar to Your LG TV in 5 Steps?
Every bar in this comparison connects the same way, and the order matters more than most guides admit. Do these in order and you avoid most of the ownership complaints we read.
Use the eARC port. On most LG sets it is HDMI port 2, and it is labelled eARC or ARC. That is the port that sends audio back from the TV to the bar, which is what carries Dolby Atmos and DTS:X. Optical works as a fallback but loses those formats.
Plug the bar in before anything else. Connect only the soundbar first and confirm the LG TV remote controls its volume and power over HDMI-CEC. Adding a console and a streaming device first is the most common cause of the control handoff failing.
Set the TV sound output. On webOS, go to Settings, then All Settings, then Sound, then Sound Output, and choose the HDMI ARC or eARC device. Set TV Speaker to Off unless you are enabling WOW Orchestra.
Turn off competing processing. Switch off LG Sound Optimization, AI Sound Pro and any similar feature on the TV, then use the soundbar’s own Cinema or Movie mode. Owners on the S70TY report the difference is immediate.
Run calibration last. If the bar has a microphone-based room calibration, run it in the evening with the room in normal use, and re-run it if you move furniture.
Bluetooth is a last resort. It adds compression, it introduces lip-sync delay and it removes the ability to control volume from the TV remote. Use it for music from your phone, not for the TV.
If your LG TV has only four HDMI inputs, work outwards from the soundbar. Keep one input free at all times for a streaming device and route everything else you own through the bar’s own HDMI inputs, if the bar has them, or add an inexpensive HDMI switch. Owner threads on 4-input boards describe exactly this frustration with a console, an Apple TV and a soundbar competing for ports on a newer panel.
LG Soundbar vs Third-Party Soundbar for an LG TV
This is the most common question in LG owner threads, and the honest answer is that same-brand pairing is optional, not required. The TV and the soundbar communicate over standard HDMI and optical regardless of logo. What WOW Orchestra adds is a feature, not basic compatibility.
Owner experience in the forums splits on taste rather than facts. One poster who owned two different LG soundbars before trying Sonos reported the Sonos was the better of the three, while other posters in the same discussion found Sennheiser Ambeo far superior. An AVForums thread on an older LG B9 recommended the Sony HT-G700 for value and the Dali Katch for sound quality at that tier.
The practical differences come down to integration and app behaviour. LG bars give you WOW Orchestra, WOW Interface and a single LG remote, and the LG Soundbar app handles updates and tuning. Sonos gives you a mature app, AirPlay 2, Spotify Connect, multi-room and reliable Trueplay calibration, but no TV speaker integration and no included remote.
Bose and Polk, in the two non-LG budget picks here, do the least and win the most. Neither depends on a phone app for basic function, both hand you every cable in the box, and both work identically on an LG, Samsung or Sony panel. If you want fewer boxes to configure and a TV that controls everything with the remote you already hold, either is a defensible choice.
Our rule of thumb: buy an LG bar if you own a recent LG TV and want WOW Orchestra or a single-remote setup. Buy a third-party bar if you want the best sound per pound, a more reliable app, or a system that works across brands when you replace the TV.
How to Choose the Best Soundbars for LG TV?
Check the channel count against your room. Numbers like 3.1.3, 5.1.3 and 9.1.5 describe left, centre, right, subwoofer, height and rear channels. A 3.1.1 or 3.1.2 bar suits a bedroom and a 55-inch TV. Genuine wireless rear speakers matter once you are past 65 inches in a room where you sit well back from the screen.
Prioritise eARC over everything else. Without eARC you lose Dolby Atmos and DTS:X, and optical is the fallback. Every bar in this comparison has an eARC-capable HDMI path except the Bose TV Speaker, which offers HDMI-ARC and optical only.
Treat dialogue modes as the deciding feature. Every LG owner complaint in our research centred on speech intelligibility, not channel count. VoiceAdjust on the Polk Signa S4, VoiceMX on the ULTIMEA and Clear Voice Plus on the S40TR all exist for the same reason.
Check the height of the bar against your TV. A 2.2-inch body like the Bose TV Speaker or the 2.36-inch Polk will sit under almost any LG panel. A 2.5-inch bar is usually fine. Above 3 inches you should measure, because blocking the bottom bezel or the infrared sensor is a common return reason.
Match the system to the screen size. A 48-inch or 55-inch TV is served by a compact bar plus a subwoofer. A 65-inch or 77-inch screen wants height channels and rears. An 83-inch or 97-inch panel in an open-plan room needs real rear speakers and calibration, which is where the S95TR earns its place.
Plan the HDMI ports before you buy. Newer LG boards ship with four HDMI inputs, and a soundbar, console and streaming device already use three. Plug the bar in first, keep one port free, and never route your only 4K 120Hz source through a switch that cannot pass it.
Check gaming features if you own an LG HDMI 2.1 TV. VRR and ALLM passthrough at up to 120Hz appear on the S95TR, S90TR and S70TY. The Polk Signa S4 reports 16 ms of audio latency, and the third-party bars do not advertise gaming modes at all.
Decide on app dependence. LG bars and the Sonos Arc Ultra lean on their apps for tuning and updates. The Polk Signa S4 and the Bose TV Speaker work from the remote alone. If you dislike configuring anything on a phone, that difference matters more than any spec line.
Frequently Asked Questions
Which soundbar is suitable for an LG TV?
Any soundbar with an HDMI eARC or ARC output will work with an LG TV. The Sonos Arc Ultra is our best overall pick, the LG S90TR suits C-series OLED owners who want WOW Orchestra, and the Polk Audio Signa S4 is the best value option. All of them connect over a single HDMI cable and let the TV remote control volume.
Which LG soundbar is considered the best?
Among LG’s own bars, the LG S95TR is the most capable with 9.1.5 channels, true wireless rear speakers, room calibration and 120Hz passthrough. If you want less hardware, the LG S90TR gives you 7.1.3 channels with wireless rears and WOWCAST at 4.5 stars across 118 reviews.
Is LG soundbar better than Sonos?
It depends on what you value. LG bars win on TV integration through WOW Orchestra and WOW Interface, plus bundled wireless rear speakers. Sonos wins on app reliability, AirPlay 2, multi-room and Trueplay calibration. Owner threads on Reddit and Audiogon are split, with some preferring Sonos after trying both and others finding Sennheiser Ambeo superior to either.
Are Bose soundbars better than LG?
The Bose TV Speaker in this guide is a stereo system with 35 watts of output and no height channels, so it is not better for films. It is better for one specific job: making dialogue clear on a small TV in a small room. For a large LG OLED, the Atmos-equipped LG and third-party bars here produce a much wider and deeper soundstage.
Can I use WOW Orchestra on my LG soundbar?
Yes, but only when you have a supported LG TV and a supported LG soundbar. The S95TR, S90TR, S70TY and S40TR all support it. Enable it in the LG SoundBar app under the settings gear, then Sound Settings, then WOW Orchestra. Some owners disable it again because the TV speakers make the result worse for them.
How do I make my LG TV sound better?
Connect a soundbar to the eARC HDMI port, set the TV sound output to that device, turn off LG Sound Optimization and AI Sound Pro, then use the soundbar’s Cinema or Movie mode. Turning off the TV’s own processing and running the soundbar’s room calibration are the two changes owners report mattering most.
Final Verdict for LG TV Owners in 2026
After comparing all eight against the same criteria, the Sonos Arc Ultra is our best soundbar for an LG TV in 2026. It pairs over one HDMI eARC cable, needs no app to control the basics, handles 9.1.4-channel Dolby Atmos cleanly and holds the highest owner rating in the group at 4.6 stars from 721 reviews.
If you own a recent LG TV and want the TV’s own speakers in the mix, the LG S90TR is the pick, with the LG S95TR for 77-inch and larger screens where real rears and height channels fill the room. For value, the Polk Audio Signa S4 gives you Atmos and a real subwoofer with no app required, and the ULTIMEA Poseidon M60 covers small rooms with a wired sub and a 10-band equaliser.
Check your HDMI port count, plug the soundbar in first, and turn off the TV’s own sound processing before you judge anything. That single setup order fixes most of the frustrations LG owners report. Model names and pricing change often, so confirm current details on the listing before you buy.
