Rated 5 out of 5 by from Great sound The sound guality is excellent in all the different modes. I like the way it syncs with my LG television. The auto on and off feature makes it seamless to use.

Running this through an optical cable. Every time the bar is on, the audio and video cuts out for brief moments. Tv is an LG 43UJ6200. When I turn the bar off, everything is fine. Will the firmware update solve this issue?

Is my 43LF5400 TV compatible with this sound bar. And if now what is?

Asked by: Tristin
Hi Tristin. The LG 2.1 ch High Resolution Audio Sound Bar, Model # SJ4Y can be paired with a TV that supports Bluetooth for wireless streaming or it can be connected to a TV that has an Optical Digital Audio Output on it or one that has an HDMI Port that Supports HDMI ARC functionality. Regrettably, your LG Full HD 1080p LED TV - 43" Class (42.5" Diag), Model # 43LF5400 is an entry level model that is designed for people who are not looking to add any external audio systems to augment the TVs sound. It does not have any feature that allows you to connect any Sound Bar to it or any other external audio system...^IFV

 How far can the wireless subwoofer be away from the main unit ?

I have my Soundbar hooked up through the HDMI ARC cable. My Room is not that big. Although sound is good volume is horrible. I have to turn it up to 100 to even get decent volume. Is this to be expected? I would think Max Volume would be very loud.

Asked by: Opieeee
We may need to do some troubleshooting. Please give us a call when you are with your unit at 1-800-243-0000. ^AC
