What People Are Saying

Rated 5 out of 5 by from Absolute Awesome Sound I bought this and out of the box it's like PNP plug in play. Exceptional sound from this LG sound bar system. The SH4 puts out some good subwoofer low LFE effects with proper volume level. Would like to see some type of volume number levels to indicate how loud your are playing output.

Can I mount it on top of a tv?

Asked by: Kennyskeys
We appreciate your interest in this Sound Bar System. This device can be wall mounted above a TV, if you so choose, but the installation bracket is not configured to be connected directly to a TV. Also, most televisions are not designed to have a Sound Bar connected physically in such a fashion.
