**Short answer:** With a recent LG OLED or QNED TV, an **LG soundbar** adds **WOW Orchestra** (the TV's speakers play along with the bar) and the **WOW Interface** (soundbar settings in the TV's menu). From LG's spec sheets: the **S95TR** (9.1.5 channels with rear speakers) for full surround, the **SC9S** (3.1.3, with a bracket that matches the OLED C series) for a C-series OLED, the **S70TY** (3.1.1) as the mid-range match for QNED TVs, and the **S40T** (2.1, ARC only) as a basic upgrade. Any eARC soundbar works with an LG TV, but only LG bars get WOW Orchestra. LG's 2025 flagship, the S95AR, succeeds the S95TR.

## Key takeaways

- **WOW Orchestra:** LG soundbar + compatible LG TV play together; the S95TR, SC9S and S70TY list it, the budget S40T doesn't.
- **For an OLED C5 or C4:** the SC9S (38.4 in) is designed to match the C series and can attach with LG's bracket.
- **Passthrough:** LG's bars pass 4K, Dolby Vision and HDR10 through, but not 4K 120 Hz: connect consoles to the TV.
- LG TVs send **Dolby Atmos** (and DTS) over eARC to any Atmos soundbar.

LG TVs, especially the OLEDs, have thin cabinets with little room for speakers, so a soundbar is one of the most noticeable upgrades you can make. Any bar connected to the TV's eARC port works; an **LG** bar adds features that only work between LG products. Here's what they are and how LG's current soundbars compare, from LG's own spec sheets.

## LG's soundbars compared

| Model | Channels | Bar width | In the box | HDMI input (passthrough) | LG TV features |
|---|---|---|---|---|---|
| **S95TR** | 9.1.5 | 49.2 in | Bar, wireless subwoofer, 2 rear speakers | 1 input: 4K, Dolby Vision, HDR10 | WOW Orchestra, WOW Interface, WOWCAST (wireless) |
| **SC9S** | 3.1.3 | 38.4 in | Bar, wireless subwoofer | 1 input: 4K, Dolby Vision, HDR10 | WOW Orchestra, WOW Interface, OLED C-series bracket |
| **S70TY** | 3.1.1 | 37.4 in | Bar, wireless subwoofer | 1 input: 4K, Dolby Vision, HDR10 | WOW Orchestra, WOW Interface |
| **S40T** | 2.1 | 28.4 in | Bar, wireless subwoofer | None (ARC only) | WOW Interface |

All except the S40T have HDMI eARC and support Dolby Atmos and DTS:X. LG launched a new flagship, the **S95AR**, in 2025 as the S95TR's successor.

## What you get with an LG soundbar on an LG TV

- **WOW Orchestra:** the TV's speakers and the soundbar play together instead of the TV going silent; the extra drivers fill out dialogue and height.
- **WOW Interface:** the soundbar's settings and sound modes appear in the TV's own menu, controlled with the TV remote.
- **WOWCAST** (S95TR): a wireless connection from compatible LG TVs, with Dolby Atmos, so the bar needs no HDMI cable.

These need a compatible LG TV (recent OLED and higher-end QNED models; LG lists compatible TVs for each soundbar on its product pages). They're conveniences and a modest sound improvement, not a reason to replace a non-LG bar you like.

## Which one to choose

**Full surround: S95TR (or the newer S95AR).** 9.1.5 channels, with rear speakers that also have up-firing drivers, and the widest bar at 49.2 in, which suits 65-inch-and-up TVs. Wireless connection to compatible LG TVs via WOWCAST.

**LG OLED C-series owners: SC9S.** Designed as the C series' matching bar: three up-firing speakers (3.1.3), 38.4 in wide, and a bracket that joins it to the TV's stand. Check that the bracket in the box, or LG's accessory bracket, fits your C-series year; the sheet lists the C2/C3 bracket.

**Mid-range and QNED TVs: S70TY.** LG markets it as the QNED TVs' matching bar: 3.1.1 channels with Dolby Atmos and a wireless subwoofer, 37.4 in wide, for 50–65-inch TVs.

**Basic upgrade: S40T.** A 2.1 bar with a wireless subwoofer: clearer dialogue and real bass for little money, but **ARC rather than eARC**, no HDMI input and no Dolby Atmos or WOW Orchestra. Fine for a bedroom TV.

## Connecting to an LG TV

- On the **LG C5**, the eARC port is **HDMI 2** (from LG's spec sheet). Use it for the soundbar.
- **Consoles:** LG's soundbars pass 4K video through, but their sheets don't list 120 Hz. Connect a PS5 or Xbox to one of the TV's 4K 120 Hz inputs (all four on the C5) and let eARC carry the sound to the bar.
- In the TV's sound output menu, choose the soundbar or **WOW Orchestra** if available.

## Sizing the soundbar to the TV

A bar about **70–100% of the TV's width** looks right:

- **48-inch and 55-inch C5** (42.2 and 48.1 in wide): SC9S (38.4 in) or S70TY (37.4 in)
- **65-inch C5** (56.7 in): SC9S, S70TY or S95TR (49.2 in)
- **77- and 83-inch C5** (67.4 and 72.5 in): S95TR

LG's OLEDs sit low on their stands (the 65-inch C5 is 34.6 in tall on its stand against 32.5 in without, so the screen starts about 2 in above the furniture). A bar 2.5 in tall placed directly in front can clip the bottom of the picture; mounting the bar on LG's bracket, or the TV on the wall, avoids that. See [65-inch TV dimensions](/tv-dimensions/65-inch/).

## Frequently asked questions

### What is the best soundbar for an LG TV?

For an LG OLED C-series TV, the LG SC9S (3.1.3 channels, matching design and bracket). For full surround, the LG S95TR or its 2025 successor S95AR, with rear speakers. For a mid-range QNED TV, the S70TY (3.1.1). Any soundbar with eARC works, but only LG's get WOW Orchestra.

### What is WOW Orchestra?

An LG feature that plays sound through the TV's speakers and a compatible LG soundbar at the same time, so the TV adds detail instead of being muted. It needs a compatible LG TV (recent OLED and QNED models) and soundbar, and is switched on in the TV's sound settings.

### Does the LG SC9S fit the LG C5?

The SC9S is LG's C-series matching soundbar: 38.4 in wide, which sits centered under the 48.1-inch-wide 55-inch C5 or the 56.7-inch 65-inch C5. Its sheet lists a synergy bracket for the C2/C3; check LG's accessory page for the bracket that fits your C-series year.

### Do non-LG soundbars work with LG TVs?

Yes, through the TV's HDMI eARC port (HDMI 2 on the C5), including Dolby Atmos. You lose WOW Orchestra and the WOW Interface; most bars still respond to the LG remote via HDMI-CEC (SIMPLINK).

### Can I connect my PS5 to an LG soundbar?

You can, but LG's soundbars pass 4K video through without 120 Hz. For 4K 120 Hz and VRR, connect the PS5 to one of the TV's 4K 120 Hz ports (all four on the C5) and let the TV send audio to the soundbar over eARC.
