What people are saying

Rated 2 out of 5 by from Worked great until 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.

Are they compatible with LG - 1000W 6-Ch. 3D Smart Blu-ray Home Theater System - Black

Asked by: adzeb
As indicated in its title, the LG GX 3.1 ch High Res Audio Sound Bar with Dolby Atmos, Model # GX is specifically designed for compatibility with the LG GX with Gallery Design 4K Smart OLED TV w/AI ThinQ® series (77",65" and 55" screens). It is not compatible with LG Home Theater Systems...^Ivan

This is built to match the width of the 55" GX OLED. Do you make a model to match the 77"? I can only find the 55" model in stores. If you do make a 77" model, can you provide a link to where it is available to buy?

Asked by: BryceVegas
I actually believe the physical width of the soundbar matches the physical width of the 65" GX OLED (56.9" wide). I also don't believe LG has any intentions of manufacturing different physical widths to match the other panel dimensions (55" or 77").

The above specs mentions 4k passthrough, but will this passthrough 4k at 120hz the Gx TV can receive? From Gx TV: "up to 40Gbps bandwidth, 4K 120Hz 4:4:4." Owner manual of this bar has 4k 30 hz at 4:4:4 for HDMI output.
