5. LG S20A 2.0-Channel Soundbar

Best for: Small rooms and LG TV owners

The LG S20A is a compact 2.0-channel soundbar designed to improve built-in TV audio without adding a separate subwoofer.

Dolby Digital and DTS Digital Surround support add clearer, more detailed sound than many television speakers. At $99.99, it targets shoppers who want a straightforward upgrade at a modest price.

LG TV owners get the most from this model. HDMI ARC connects the television and soundbar with one cable, while WOW Interface lets one remote adjust volume, sound modes, and connection settings.

The system includes three sound channels, a dedicated subwoofer, and an up-firing center channel. That center speaker focuses on dialogue, which can help voices remain clear during busy action scenes. Dolby Atmos adds height effects for a wider sense of space.

LG TV owners get the strongest feature set. WOW Orchestra combines the TV’s speakers with the soundbar, while WOW Interface lets one LG remote adjust volume, sound modes, and connection settings.

2. LG S95TR 9.1.5-Channel Home Theater Soundbar

Best for: LG OLED owners building surround sound

LG’s WOW Orchestra can combine the soundbar with compatible LG TV speakers. WOW Interface also lets the TV remote adjust volume, sound modes, and connection settings. Built-in WOWCAST can send Dolby Atmos audio wirelessly from a compatible LG TV, reducing cable clutter.

Buying Guide

HDMI eARC compatibility matters most when choosing a soundbar for the LG OLED CX. It sends high-quality Dolby Atmos audio from the TV, while optical cables cannot carry every surround format.

• HDMI connection: Choose a model with HDMI eARC, not optical-only audio. At least one extra HDMI input helps connect a console or streaming box. HDMI 2.1 passthrough is useful for 4K gaming at 120Hz.
• Channel layout: A 3.1.2 or 5.1.2 system adds a center channel for clearer speech and upward-firing drivers for Atmos effects. Basic 2.0 bars suit smaller rooms but create less separation.
• Soundbar width: Pick a bar between 30 and 48 inches for a 48-inch CX, or up to 55 inches for the 65-inch model. Keep it below the screen without covering the TV’s lower edge.
• Bass hardware: A wireless subwoofer adds impact for films and games. For rooms above 200 square feet, choose a separate subwoofer rather than a compact bar alone.
• Price and expansion: Expect to spend $300 to $800 for a strong bar with eARC and Atmos. Rear speakers can add $150 to $400 later, so check upgrade options before buying.

If you must compromise, prioritize HDMI eARC support and clear dialogue.

Frequently Asked Questions

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

Choose a soundbar with HDMI eARC, Dolby Atmos support, and a size that fits your room and TV stand. The LG CX can pass high-quality audio through its eARC-capable HDMI connection, while optical audio remains an option for simpler setups in many cases.

What features should an LG CX soundbar have?

Look for Dolby Atmos, HDMI eARC, Bluetooth, and a dedicated subwoofer if you want fuller bass from an LG OLED CX. A 2.1-channel bar uses two main channels plus bass, while a 5.1.2 system adds surround channels and two height channels.

Can a soundbar connect directly to the LG CX?

Yes, a compatible soundbar can connect to the LG CX through HDMI eARC, optical audio, or Bluetooth. HDMI eARC is usually the strongest choice because one cable can carry TV audio and support formats such as Dolby Atmos when supported.

Are compact soundbars good for the LG OLED CX?

Yes, compact soundbars work well with the LG CX in small rooms, but larger spaces benefit from a subwoofer or separate rear speakers. A bar around 24 to 32 inches wide can fit below many 48-inch or 55-inch CX models, but measure your stand first.

Conclusion

LG SC9S 3.1.3-Channel Soundbar is the top recommendation for LG OLED CX owners who want fuller dialogue, stronger bass, and a matched LG setup without adding a separate receiver. If your priority is saving space or money, pick a compact 2.1-channel LG soundbar instead, since it needs less room and usually costs less. Before buying, double-check the bar’s width against your TV stand, compatibility with the CX’s HDMI ARC or eARC connection, included speaker quantity, and current price. The SC9S suits buyers who want a wider, more cinematic presentation with height channels, but its larger cabinet and higher cost may not fit every room. Check return terms too, since sound can vary with room layout.
