These seven soundbars are ranked from the most practical option down to our top pick.

7. LG S20A 2.0-Channel Soundbar

Best for: Small rooms needing clearer TV audio

The LG S20A is a compact 2.0-channel soundbar priced at $99.99. It combines two front-facing audio channels with a passive radiator, which helps add weight to voices, music, and movie effects without a separate subwoofer. Dolby Audio and DTS Digital Surround support can improve clarity over many built-in TV speakers. AI Sound Pro adjusts the equalizer as content changes, aiming for clearer dialogue in shows and stronger impact during sports or action scenes.

An HDMI ARC connection lets a compatible LG TV and soundbar share one cable. LG TV owners also get TV Synergy features, including WOW Orchestra, which uses both sets of speakers together. The WOW Interface lets one remote adjust volume, sound modes, and connection settings. The LG ThinQ app adds a three-band equalizer for bass, midrange, and treble control. A metal grille protects the speaker area from dust and debris. Still, this is a basic two-channel system, not a full home theater package.

Pros

• Passive-radiator design adds bass without requiring a separate subwoofer.
• AI Sound Pro adjusts sound for dialogue, music, sports, and action content.
• HDMI ARC and WOW Interface simplify control with a compatible LG TV.

Cons

• The 2.0-channel layout lacks a dedicated subwoofer and rear speakers, so bass and surround effects have limits.

Dolby Atmos audio can create height effects, while the soundbar’s three main channels handle voices and front-facing sound. Its built-in WOWCAST supports wireless Dolby Atmos connections, which can reduce cable clutter with compatible LG TVs.

Several features work best inside the LG ecosystem. WOW Orchestra combines the soundbar and compatible LG TV speakers, while WOW Interface lets one TV remote adjust volume, sound modes, and connection settings.

The LG Sound Suite H7 is a premium 9.1.6-channel soundbar priced at $899.99.

Front-, side-, and up-firing drivers direct sound around the room, while Dolby Atmos adds height effects. The black cabinet has a minimalist design intended to sit beneath an LG television.

Its strongest feature is placement flexibility. Dolby Atmos FlexConnect can adjust the sound field when paired with compatible M5 or M7 wireless speakers.

4. LG S6FTR 5.1-Channel Home Theater Soundbar

Best for: LG TV owners wanting surround

The LG S6FTR is a 5.1-channel home theater system with a soundbar, wireless subwoofer, and wireless rear speakers.

At $299.99, it targets viewers who want a fuller setup than a TV’s built-in speakers without buying a separate receiver.

The setup stays simple, with HDMI ARC using one cable between a compatible LG TV and the soundbar.

LG’s TV-focused controls are the main attraction. WOW Interface lets one LG remote adjust volume, audio settings, sound modes, and connection status on the TV screen.

Best for: LG QNED TV owners with limited space

The LG S70TY is a slim 3.1.1-channel soundbar with a wireless subwoofer. Its smaller width and depth suit LG QNED TVs on a stand, while wall mounting offers another setup option. A metal grille helps keep dust and debris away from the speakers, and the crest-style front adds a cleaner look than many basic bars.

The standout feature is its up-firing center channel, which aims sound toward the listening position for clearer dialogue. Dolby Atmos adds overhead-style effects, while the bar can use compatible LG TV speakers at the same time through WOW Orchestra. One LG remote can adjust volume, sound modes, and connection settings. For movies and music, the system can turn two-channel audio into a wider multi-channel presentation. Gamers also get passthrough support for refresh rates up to 120Hz.

At $249.99, it offers a fuller setup than a standalone bar without requiring a separate receiver. Dolby Digital and DTS Digital compatibility supports TV, movie, and music playback. The metal grille protects the bar from dust and debris while giving it a restrained look.

Buying Guide

HDMI eARC compatibility is the most important factor when choosing a soundbar for an LG CX. It lets the television send Dolby Atmos and high-quality surround audio through one cable, while also supporting volume control from the LG remote.

• HDMI connection: Choose a model with HDMI eARC, not only standard ARC. Use a certified Ultra High Speed HDMI cable up to 6 feet for reliable connections.
• Channel layout: Select at least 3.1 channels for clearer dialogue. A 5.1.2 or 7.1.2 system adds upward-firing speakers for Atmos effects.
• Soundbar width: Match the bar to your TV stand. A 36-to-48-inch model suits most 48-, 55-, and 65-inch CX televisions without crowding the screen.
• Subwoofer setup: Pick a package with a separate wireless subwoofer for movie bass. A driver around 6.5 inches or larger usually fits medium and large rooms better.
• LG integration: Confirm HDMI-CEC support, called SIMPLINK on LG TVs. Bluetooth, optical input, and at least one extra HDMI input also help connect consoles and music players.

If you cannot have everything, prioritize HDMI eARC and clear dialogue before extra channels or stronger bass.

Frequently Asked Questions

How do I choose a soundbar for an LG CX?

Choose a soundbar with HDMI eARC, Dolby Atmos support, and a width that fits your LG CX setup. The CX has an HDMI eARC port, so this connection can carry higher-quality TV audio than optical in compatible systems. A bar around 30 to 48 inches usually suits 48-, 55-, and 65-inch models.

What soundbar works with the LG CX?

A soundbar with HDMI eARC or ARC, optical input, or Bluetooth can work with an LG CX, but HDMI eARC is the strongest choice for advanced formats. Check the model’s input list before buying. For example, Dolby Atmos playback generally needs a compatible TV app or source and an HDMI connection.

Can I use Dolby Atmos with an LG CX soundbar?

Yes, you can use Dolby Atmos with the LG CX when the soundbar, content source, and connection all support Atmos. Use HDMI eARC for the broadest compatibility, then enable eARC and digital sound output in the TV settings. Streaming apps may require a plan that includes Atmos audio.

Are subwoofers necessary for an LG CX soundbar?

A subwoofer is not necessary, but it adds deeper bass to movies, music, and games with an LG CX. Choose a bar-only system for dialogue and a smaller footprint, or consider a 2.1 package if explosions and music matter. A wireless subwoofer can add floor space, often about 12 to 16 inches wide.

Conclusion

LG S40TR 4.1-Channel Home Theater Soundbar is the top pick for LG CX owners who want clearer dialogue, surround sound, and a simple matching setup without paying flagship prices. If your priority is the widest, most cinematic surround field, choose the Samsung HW-Q990D instead, since its larger speaker package adds more channels and dedicated rear speakers. Before buying, double-check the soundbar’s width against your TV stand, LG CX compatibility, included speaker count, and current price, since bundles and discounts change. Also confirm support for HDMI eARC, Dolby Atmos, a wireless subwoofer, and rear channels. For many CX households, the S40TR offers a balanced upgrade for movies, shows, and everyday listening.
