What people are saying

Rated 2 out of 5 by from Good looking design, poor quality I bought this a few years ago with a top of the line LG TV. It matched the style and size, giving my living room a clean connected look. I even got the rear speakers from LG. I appreciated the wireless transmitter to simply cables running from the unit. However, after a year, the subwoofer stopped working. I cannot replace just the sub, and it would be insane to replace the entire sound system. The sub is cheap and LG discontinued this entire line because of poor quality.

Rated 1 out of 5 by from Junk Subwoofer is dead after three years. Pairs with sound bar, but will not produce any sound. Really nothing else matters--not worth buying if it's not built to last.

Rated 1 out of 5 by from Subwoofer broke within the 1st year Waste of money BTW this speaker is not cheap subwoofer is no good and unavailable to replace so frustrating
