5 Top Soundbars for the LG CX

These five soundbars are ranked from solid options down to the top pick, with LG CX compatibility and room-filling features guiding the order.

5. LG S55TR 5.1-Channel Soundbar

Best for: Affordable movie nights with surround sound

The LG S55TR is a 5.1-channel soundbar system priced at $171.99. It includes the main bar, a subwoofer, and rear speakers for a fuller home theater setup than a TV’s built-in audio. Dolby Audio supports clearer dialogue and a wider sound field for movies, shows, and games. The five-channel layout also gives sound more separation around the room.

The rear speakers connect wirelessly, so you do not need a separate receiver between them and the soundbar. That can reduce cable clutter, although the system still needs careful speaker placement. LG uses a crest-style design on the bar, which gives it a cleaner look than many basic black speakers. One remote can control the soundbar and a compatible LG TV, while the LG Soundbar app lets you adjust the bar and rear-speaker settings. The feature list does not specify HDMI, optical, or Bluetooth details, so check the connection options before buying.

Pros

• Five channels and rear speakers create a more spacious movie soundtrack.
• Dolby Audio can improve dialogue clarity and overall sound separation.
• Wireless rear-speaker connectivity avoids the need for a dedicated receiver.

Cons

• A 5.1-channel setup needs more room and positioning than a compact two-speaker bar.
• Connection details are not listed, so TV compatibility should be confirmed first.

4. LG S95TR Home Theater Soundbar

Best for: LG OLED owners building surround sound

The LG S95TR is a 9.1.5-channel home theater system with a soundbar, wireless subwoofer, and two rear speakers. It supports Dolby Atmos and DTS:X for overhead and directional effects. Three up-firing channels sit in the bar, including a center channel designed to keep voices clearer. The rear speakers connect wirelessly, but each one still needs a nearby power outlet.

Its strongest feature is the way it works with compatible LG televisions. WOW Orchestra can combine the TV and soundbar speakers, while WOW Interface lets one remote adjust volume and sound modes. Built-in WOWCAST can send Dolby Atmos audio wirelessly from a compatible LG TV, reducing cable clutter. Room calibration uses a built-in microphone to measure the space and rear-speaker positions, then adjusts the sound. Gamers also get VRR and ALLM support with passthrough refresh rates up to 120Hz. Google Assistant, Alexa, Chromecast, and AirPlay 2 add useful control options.

Pros

• Three up-firing channels create a wider Dolby Atmos soundstage.
• Wireless rear speakers allow more flexible placement around the room.
• Room calibration adjusts audio for speaker position and room dimensions.

Cons

Its layout separates left, right, center, and rear audio for clearer dialogue and wider effects than most TV speakers. Dolby Audio handles compatible movie and show soundtracks, while automatic audio adjustment changes the balance for sports, music, and action scenes. At $299.99, it targets buyers who want a full surround setup without adding a separate receiver.

LG TV owners get the strongest feature set. WOW Orchestra can combine the TV’s speakers with the soundbar, and WOW Interface lets one LG TV remote adjust volume, sound modes, and connection settings. The LG Soundbar and ThinQ apps also provide treble, midrange, and bass controls from a compatible device. A metal grille protects the bar from dust and gives it a cleaner look, though LG does not list support for Dolby Atmos here.

Best for: Affordable living-room surround sound

The LG S40TR is a 4.1-channel home theater system with a soundbar, wireless subwoofer, and wireless rear speakers. Dolby Digital and DTS Digital support handle movies, shows, music, and games. Its separate subwoofer adds low-end impact, while the rear speakers spread effects beyond the TV. The system delivers more room-filling sound than a basic two-channel bar without requiring a separate AV receiver.

Several features make daily use easier. Clear Voice Plus adjusts dialogue for better speech clarity, and the smart up-mixer can expand two-channel audio across the system. LG TV owners get extra control through WOW Interface and WOW Orchestra, which let the TV and soundbar work together under one remote.

1. LG S70TY Soundbar

Best for: LG QNED living-room setups

The LG S70TY is a 3.1.1-channel soundbar made to pair with LG QNED televisions. It includes a wireless subwoofer and an up-firing center channel designed to keep dialogue clear while adding height effects. Dolby Atmos support creates a broader sense of space for films and shows. Its compact shape fits beneath a QNED on a TV stand, and wall mounting is also supported. A metal grille protects the speakers from dust and debris.

LG’s WOW Orchestra combines the TV speakers with the soundbar, so both can play together. WOW Interface also lets the LG TV remote adjust volume, sound modes, connection status, and other settings. The system can convert two-channel audio into a multi-channel presentation, which may help older shows and music feel fuller. For gaming, HDMI passthrough supports refresh rates up to 120Hz. The soundbar is also ready for LG’s wireless 2.0-channel rear speakers, but those speakers are not included in this setup.

Pros

• Up-firing center channel gives dialogue extra focus.
• Wireless subwoofer adds low-frequency impact without a subwoofer cable.
• 120Hz passthrough suits compatible consoles and gaming TVs.

Buying Guide

The most important factor is HDMI eARC compatibility. The LG CX can pass higher-quality audio formats through eARC, allowing a matching soundbar to deliver Dolby Atmos without using older optical audio.

• HDMI connection: Choose a model with HDMI eARC, not only optical or standard ARC. Confirm it has at least one HDMI input if you connect a console or streaming box.
• Room size: For rooms under 150 square feet, a 2.1 or 3.1-channel bar may fit well. Larger spaces often benefit from a 5.1 system or separate rear speakers.
• Dolby Atmos: Look for Dolby Atmos decoding and upward-firing drivers if height effects matter. A bar measuring 35 to 45 inches wide should suit a 55-inch television.
• Subwoofer setup: A wireless subwoofer adds stronger bass for films and music. Leave about 10 inches of clearance around its vents, and confirm one comes in the box.
• Price and controls: Expect to spend about $250 to $800 for a capable setup. LG TV remote support, Bluetooth, night mode, and dialogue enhancement improve daily use.

If you must compromise, prioritize HDMI eARC compatibility, then choose the speaker layout your room can accommodate.

Frequently Asked Questions

How do I choose a soundbar for the LG CX 55?

Choose a soundbar with HDMI eARC, a compact width, and sound modes that suit your room. The LG CX 55 supports eARC, so a bar with that connection can receive higher-quality audio and Dolby Atmos formats from compatible sources. For a narrow stand, check models under about 40 inches wide.

What size soundbar works best with the LG CX 55?

A soundbar between 30 and 40 inches usually fits the LG CX 55 without looking too small. Measure your TV stand first, since the television is 48.3 inches wide without its feet. A low-profile design also reduces the chance of blocking the screen or the remote sensor.

Can I use Dolby Atmos with an LG CX 55 soundbar?

Yes, you can use Dolby Atmos with the LG CX 55 if the soundbar supports Atmos and connects through HDMI eARC. The TV can pass compatible audio from supported apps and devices, but the effect depends on speaker placement. Up-firing drivers work best with a flat ceiling roughly 7 to 14 feet high.

Are wireless subwoofers worth it for this television?

Yes, wireless subwoofers are worth considering if you want stronger bass for films, music, or games and have floor space nearby. Many pair over a room-length distance, but walls and interference can affect reliability. For rooms under 200 square feet, a soundbar with built-in bass may reduce clutter and keep volume easier to control.

Conclusion

LG S70TY Soundbar is the top pick for LG CX 55 owners who want clear dialogue, stronger bass, and a simple setup without filling the room with separate speakers. If your priority is the biggest, most cinematic sound possible, choose a larger Dolby Atmos model instead, since its extra speakers and wider drivers can create a fuller surround field. Before buying, double-check the bar’s width against your TV stand, confirm compatibility with the CX’s HDMI eARC or optical connection, verify the package quantity for any included subwoofer or rear speakers, and compare the current price across reliable retailers. The right choice depends on your space, listening habits, and how much you want to spend.
