Upgrade the sound of your display's audio with the LG SN6Y GX 420W 3.1-Channel Soundbar System. It delivers up to 420W of total power, which includes a 220W wireless subwoofer for enhanced bass. Bluetooth is built into the soundbar for pairing with other Bluetooth-enabled devices, such as smartphones or tablets. Once paired, you can wirelessly stream audio from your connected source.

At 56.7" wide, the GX is recommended for displays 55" and larger. The soundbar has optical and HDMI inputs for connecting wired audio and video sources to complement the aforementioned Bluetooth connectivity. An optical cable, wall mount bracket, and remote control are included for added convenience.

Home Theater Audio
The GX soundbar provides 3.1 channels of audio and can simulate virtual surround sound with Dolby Atmos and DTS:X decoding. Dolby Atmos is designed to envelop you in sound with enhanced clarity and sound that seems to flow all around you, even overhead.
High-Resolution Audio
High-Resolution Audio is designed to sound close to the real thing. Higher sampling rates and bit depth (up to 24-bit/96 kHz) provide sound quality that surpasses CDs.
HDMI eARC Compatibility
With HDMI eARC (enhanced Audio Return Channel), you can enjoy Hi-Res content and uncompressed Dolby Atmos audio with just one cable. It takes the display-based audio, such as from apps built into your eARC-equipped TV, and sends it back to the soundbar to provide a single-cable solution.
Bluetooth Audio Streaming
Pair your compatible device to the soundbar for simple audio streaming.
Designed to Fit Your LG OLED TV
The GX soundbar is designed to pair with your LG OLED TV in both form and function with its minimalist design.
Expandable to 5.1-Channel Audio
With the optional 2-channel Rear Speaker Kit Expansion, which pairs to the soundbar wirelessly, the GX soundbar can create a more immersive experience.

LG GX Reviews

Great Sound bar for Complaining Neighbors

By Digg06
Rated 3 out of 5
Date: 2023-01-18

[This review was collected as part of a promotion.] I brought this sound bar a couple of months ago.It’s definitely louder than the L.G. T.V. I purchased.It has a wireless subwoofer that has to be close to the sound bar to work properly.I tried putting it on the side of the couch and it kept going off and on.It’s loud enough for whoever is watching t.v. And not loud enough for the neighbors to complain.

Only way to watch blockbuster movies and sports

I love the immersive sound and deep rumbles the floor speaker provides. Whether it's watching Top Gun:Maverick or college football, the sound experience is excellent!

I bought this less than a year ago and the subwoofer stopped working. For the price you would think that it would last longer.

[This review was collected as part of a promotion.] Pros: This 5.1 ch soundbar has excellent features, generates crisp and clear sound, and supports multiple wired and wireless connection protocols. Cons: I would have appreciated additional bass from the subwoofer.

[This review was collected as part of a promotion.] This sound bar is awesome. It worked great and sounded really loud. The sound was clear and the bass shook my house. I loved it. A few months ago the subwoofer stopped working and I can not get it working. Must be because it is a poor quality product. To bead I spent lots of money on it.

I cannot recommend this product.
