Great Sound
Excellent LG Sound Bar at a knockout price which Good Guys Lutwyche team recommended as a perfect match for my 65" LG OLED wall mounted TV purchase. It was pleasing to hear from the installation technician, I've used on two previous TV/Boom Bar installations provided "unsolicited advice, I couldn't have bought a better match.

Great value
This soundbar and sub-woofer sounds much better than I expected for the price. And by using the Wow Orchestra setting on my LG OLED TV, it really comes to life by adding in the TV's speakers. The wireless sub-woofer gives a very clean bass without being boomy. Set up was super easy using the supplied HDMI eArc cable.

At a glance
The LG S70TY is a mid-range soundbar built for buyers who want cinematic TV audio without a complex speaker setup. It suits medium living rooms and bedrooms, offering immersive Dolby Atmos playback, punchy bass from the wireless subwoofer and easy HDMI eARC connection. A key limitation is that it is not as expansive or customisable as larger premium multi-speaker systems.

Things to consider
It delivers immersive sound for its size, but it will not match the wider surround separation and tuning flexibility of premium soundbars with dedicated rear speakers.
Tv compatibility score
9/10 - Excellent match for modern TVs thanks to HDMI eARC, compact under-TV design and support for Dolby Atmos content.
Movie night suitability
8.5/10 - Strong for cinematic viewing with immersive surround formats and a wireless subwoofer, though not as room-filling as systems with rear speakers.
Music playback quality
7.5/10 - Clear and punchy for casual streaming over Bluetooth, with solid bass support for everyday listening.
Room size suitability
Best suited to small to medium rooms such as bedrooms, apartments and average living rooms.
Installation ease
8.5/10 - Straightforward to set up with HDMI eARC, wireless subwoofer and included wall-mount accessories.
Key benefits
- 3.1.1 channel audio: Delivers clearer dialogue and a more layered soundstage than basic 2.0 or 2.1 TV audio setups.
- 400W total output: Provides strong room-filling sound that suits everyday viewing, gaming and music in medium-sized spaces.
- Wireless subwoofer: Adds deeper bass impact for action scenes, sport and music without needing a cable run to the soundbar.
- Dolby Atmos support: Creates a more immersive, three-dimensional audio effect for compatible movies and shows.
- Dts:X playback: Expands compatible content with more enveloping surround presentation for home cinema use.
- HDMI eARC connection: Simplifies setup with compatible TVs and supports higher-quality audio through a single cable.
- 4K 120Hz HDR passthrough: Helps gamers connect modern consoles while preserving high refresh rate video support on compatible setups.
- Bluetooth music streaming: Lets you play audio from a phone or tablet easily for casual listening without turning on extra equipment.
Q: Does the LG S70TY include rear speakers for true surround sound?
A: No. The S70TY is a 3.1.1 channel soundbar with a wireless subwoofer, not a package with separate rear speakers. Dolby Atmos effects are created from the bar itself, so it suits buyers who want cleaner setup and fewer speakers around the room.
Q: Will the LG S70TY deliver Dolby Atmos from any TV through HDMI ARC?
A: No. HDMI ARC can carry TV audio, but Dolby Atmos playback depends on your TV, streaming app and source device supporting Atmos correctly. If a TV only outputs basic formats over ARC, the soundbar will still work, but not always in Atmos.
Q: Is the 4K 120Hz HDR passthrough useful for PS5 or Xbox Series X gaming?
A: Yes. The S70TY can pass 4K 120Hz HDR from a compatible console to a compatible TV, which is useful for fast gaming without giving up higher refresh support. Your console, HDMI cable and TV all need to support those same video formats.
Q: Is the wireless subwoofer completely cable-free?
A: No. Wireless means the subwoofer sends audio without a cable from the soundbar, but the sub itself still needs mains power. That makes placement easier than a fully wired system, although it still needs to sit near a power point.
Q: Is the LG S70TY a good match for an LG TV specifically?
A: Yes. It is a convenient match for an LG TV because HDMI ARC can carry audio back to the bar and usually lets the TV remote control volume. The S70TY still works with other TV brands, but LG owners may get simpler day to day control.
Q: Is 400W enough for a medium living room, or is this better for smaller spaces?
A: The 400W output is generally well suited to a typical bedroom or medium living room, especially if you are upgrading from TV speakers. In a very large open-plan area, it will still add bass and clarity, but separate rear speakers can sound more immersive.
