Amazing sound and base
I love to put YouTube on the TV and clean the house and with this sound bar I can hear it through the whole house. Family movies are at a whole new level now with the bass. Everyone in the family loves it.

Excellent sound
I’m very happy with my LG 3.1.1CH 400W Dolby Atmos Soundbar. The sound quality is excellent, with clear dialogue, powerful bass, and an immersive Dolby Atmos experience that makes movies and TV shows much more enjoyable. It was easy to set up and works really well with my LG TV. The soundbar has a sleek design and provides a great balance between performance and value for money. Overall, I’m very impressed with the quality and performance. Definitely a great upgrade from the standard TV speakers, and I would happily recommend it to anyone looking for a good home audio system.

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
This LG soundbar is a mid-range option for people who want more cinematic TV sound without filling the room with extra speakers. It delivers strong 400W output, a wireless subwoofer and Dolby Atmos support for movies, gaming and music. It is especially well suited to medium living rooms and bedrooms. The main limitation is that it offers less surround scale than larger premium multi-speaker systems.

Things to consider
It gives a cleaner and simpler setup than full surround systems, but it will not sound as expansive or as precisely directional as premium soundbars with more channels and rear speakers.
Tv compatibility score
9/10 - Excellent for modern TVs thanks to HDMI eARC, TV remote integration and compact under-TV placement.
Movie night suitability
8.5/10 - Strong choice for cinematic viewing with Dolby Atmos, DTS:X and a wireless subwoofer.
Music playback quality
7.5/10 - Clear and punchy for casual music streaming, though not as spacious as larger premium audio systems.
Room size suitability
Best for small to medium rooms, including bedrooms and average living rooms.
Installation ease
9/10 - Easy to set up with HDMI eARC, Bluetooth and fewer speakers than a full surround package.
Key benefits
- 3.1.1 channel audio: Adds clearer dialogue and more vertical sound placement than basic 2.1 soundbars.
- 400w total output: Provides strong room-filling sound for medium living rooms and bedrooms.
- Wireless subwoofer: Delivers punchier bass for action scenes, games and music without adding more cables to the TV unit.
- Dolby atmos support: Creates a more immersive three-dimensional soundstage for movies and streaming content.
- Dts:X PLAYBACK: Expands surround effects for compatible films and shows to make audio feel more cinematic.
- HDMI eARC: Simplifies connection to compatible TVs and supports higher-quality audio through a single cable.
- 4k 120hz hdr passthrough: Helps gamers connect modern consoles while maintaining high refresh-rate video support.
- Bluetooth streaming: Lets you play music wirelessly from a phone or tablet for casual everyday listening.
Q: Does this soundbar need rear speakers for Dolby Atmos sound?
A: No. LG S70TY creates Dolby Atmos effects from its 3.1.1-channel bar and wireless subwoofer, so it works as a cleaner two-piece setup. It will not place sound behind you as convincingly as a system with dedicated rear speakers.
Q: Can PS5 or Xbox Series X run through this soundbar?
A: Yes. LG S70TY supports 4K 120Hz HDR passthrough, so a compatible console can send video through the soundbar to a compatible TV. For the simplest setup, use HDMI eARC with a TV that supports the same gaming features.
Q: Will my TV remote control the soundbar volume?
A: Yes. When LG S70TY is connected by HDMI eARC, a compatible TV remote can usually handle everyday volume control. That keeps the setup simpler, but Bluetooth playback may still need the phone or tablet for music selection.
Q: Is the wireless subwoofer still connected by a power cable?
A: Yes. The wireless subwoofer still needs its own power point, but it does not need an audio cable back to the soundbar. That gives more placement flexibility, although it still has to sit within reach of mains power.
Q: Can I stream music from my phone without the TV?
A: Yes. LG S70TY supports Bluetooth streaming, so music can play directly from a phone or tablet without using the TV as the source. Bluetooth is convenient for casual listening, while HDMI is the better option for TV audio and control.
Q: Will it suit a large open-plan living room?
A: No. LG S70TY is better suited to small and medium rooms than a large open-plan space. Its 400W output and wireless subwoofer add punch, but buyers chasing a broader surround effect may prefer a larger soundbar system.
