”Slimline looks, full-bodied sound. The soundbar does a rather good job of creating an illusion of front to back depth, with layers of sounds and instruments stretching out behind.” ’Expert Reviews’ - Recommended.

The perfect match for your 65 inch Gallery OLED TV

At just 32.5mm deep, this flush-mounted soundbar makes the perfect match for your wall-mounted OLED TV. Designed specifically to match the LG 65 inch Gallery OLED range, this premium soundbar has the style to match the award-winning Gallery Design OLEDs. At 1440mm wide, it blends seamlessly with the LG OLED65G-series TVs. A standmount is also included for freestanding the soundbar.

Dolby Atmos and DTS:X compatible
Compatible with both Dolby Atmos and DTS:X formats, you get three-dimensional sound with all compatible discs and streaming services. Just like at the cinema, Dolby Atmos and DTS:X create an immersive soundfield, with sounds such as a jet flying overhead or tropical rainforest environment, vividly recreated.

Feel the bass, with a dedicated subwoofer
The Sound Bar GX isn’t just about sound immersion, it’s about power, too. The separate subwoofer gives action movies and music serious muscle. The wireless connection means that it can be placed anywhere in the room, regardless of how close it is to the soundbar (mains power required).

Adaptive Audio for the best sound at all times
Using LG’s AI Sound Pro (Artificial Intelligence), the Sound Bar GX continuously analyses content and adjusts the sound settings to suit. If you’re watching a documentary, the system detects a strong vocal presence and adjusts the settings to emphasis clear dialogue. With music, the bass is boosted for a more dynamic sound.

Hi-Res Audio playback for sparkling music
At the heart of this LG soundbar is a top quality audio system that’s compatible with many Hi-Res music files. Hi-Res sound gives greater detail and a more natural sound. The Sound Bar GX is compatible with a range of HD audio formats, up to 24 bit/96kHz.

Compatible with 4K content, including HDR and Dolby Vision
Fitted with a HDMI 2.1 interface (HDCP 2.3), the Sound Bar GX is compatible with high quality HDR signals – including Dolby Vision. This means that 4K HDR video signals pass effortlessly from your UHD Blu-ray or streamer through the soundbar and on to your TV.

Play music via Bluetooth and USB
The Sound Bar GX isn’t just a top quality soundbar, it also makes a great speaker for music, too. Bluetooth connectivity links to your smartphone, tablet or other device and lets you stream music from services such as Spotify, Apple Music and TIDAL or simply playback your stored music. The USB interface lets you connect a suitable media player and play your stored content.

Enjoy expansive sound from the slimmest and most stylish soundbar, with the LG Sound Bar GX.

Rated 5 out of 5 by from LG Soundbar Good Soundbar, but admittedly connected to a spare Samsung TV. Struggling to get atmos working, but good quality sound vs outgoing Samsung

Rated 1 out of 5 by from Not supported by the LG sound bar app The app says it does not support the GX sound bar. Bluetooth connection with phone works perfectly, but the app doesn't work. Needs fixing, as otherwise the sound bar can not be optimised to the room's acoustics

Rated 1 out of 5 by from AVOID The bass sub unit broke within warranty period and over 5 months later I am still without a working one. It has been sent off twice for repair and been returned back to me in the same broken state both times and with no notes. The soundbar sounds terrible without the bass unit and now LG are offering me half the cost of a replacement as settlement (within warranty!!!). The bass unit cannot be purchased separately and so months of my life and I have spent chasing this up (because LG took weeks/months to respond) and now I am told I won't even receive a replacement. Abysmal customer care so be warned. I spent many thousands of pounds on a TV and soundbar and this is how I'm treated (within warranty!).

Rated 1 out of 5 by from Awful subwoofer. I had very high expectations on this, but the bass is almost inaudible, for reference I had the Logitech z906 before buying this, and it just feels like a downgrade. The speakers are ok, a little upgrade from the integrated speakers on the OLEDGX. I'm probably keeping it just for the looks. Loved eARC. Also the additional SPK8-S are a bit dissapointing...

Rated 2 out of 5 by from Seems a bit slapped together This product feels like it was rushed out the door. Lots of problems with it... 1. The pegs on the back of the speaker for mounting were not the same length. One fit fine in the bracket and the other wouldn't go. It was just a tiny bit shorter than the other peg. It doesn't appear to be adjustable in any way...just a flaw in the production. I was able to get around this by adding a washer on one side behind the bracket to move it away from the wall by 2mm. 2. The included HDMI cable is a 1.4 spec cable that lacks the bandwidth to support advanced sound formats such as Atmos that it touts as a major feature. I had to order my own ultra high speed cable to fix this issue. Ironically, the manual (that I found online, because the one in the box was a one-pager with no instructions on how to use it) specifically states to NOT use cables labeled as "high speed" and to only use "ultra" or "premium" cables, but then they include the very cable they said not to use. 3. Mounting hardware is not included. In the instructions, there's a picture of some screws and a shopping cart icon with instructions to go buy your own. I would expect a premium soundbar like this to at least include the screws to mount it. 4. There is an LED text display in the middle of the bar that indicates the source and used for changing settings, etc. There is no way, as near as I can tell, to turn that off. So I'm stuck looking at glowing "E-ARC" on my soundbar under my TV, which is very distracting, especially at night. I've seen on other soundbars that the text turns off after a few seconds of inactivity, but that doesn't seem to be the case here. Other than all of that...it sounds fine. Not knocking my socks off, but way better than the TV speakers. It's what you would expect from a thin soundbar.
