Rated 5 out of 5 by from Helps my hearing problem I would add in the directions A or B. I thought I had to do both and it took me forever & a phone call to your help desk to figure it out.

Rated 5 out of 5 by from Good audio We bought this about three weeks ago. We replaced a previous LG sound bar (purchased about a year and half ago) which my wife and I had a terrible time trying to hear and understand the dialogue. Yes we are of an age where our hearing is getting worse. This is a great improvement! No more arguments about what was said or turning it up.

I have the LASC 47 sound bar. Even at full volume it's not very loud. I've tried various streaming sources (youtube, youtube tv, hulu, netflix) and none of them are nearly as loud as the speakers on my Samsung 48mu8000. Is this normal?

Asked by: Psquaretrader2123
Hate to hear Psquaretrader2123, sounds like we may need to perform some troubleshooting. Please give us a call at 1-800-243-0000 when you are with your unit. ^AC

Which model is better LG SJ4Y-S LG LASC47

Asked by: Looka25
I don't why LGJoel said LASC47 not compatible with Spj4-s. LG wed site for LASC47 says it is compatible.

Which rear speakers work with unit? Clearly states surround sound compatible but it’s not clear (and appears to contradict) other reviews. 

Asked by: SDinsunnyFL
The SPJ4-S is compatible with the LASC47. If you are in need of any assistance, have additional questions, or would just like to see our helpful tips, check us out on Twitter @LGUSSupport ^CP

When I turn off my TV and sound bar then turn it back on the sound won't come back on. So I have to unplug the sound bar and plug it back in to get sound. Why dose it do this.

Can you hook the LASC 7 to a receiver and if so how? I want to be able to run the sound from the TV and my other devices i.e., dvd blue ray ps2 vcr etc through both the soundboard and my home theater system simultaneously. Can’t seem to figure out how.

Asked by: Ibanez1
This will depend on your receiver as the LASC47 does have a HDMI ARC out port on it. ^AC

how far away can you be from these speakers and still be able to use Bluetooth to stream music from a smart phone? Unobstructed by walls of course. 

Asked by: IchagoSushi
