LG S40T Reviews

Great value for the money

By James
Rated 4 out of 5

I really like this soundbar. It has good imaging and excellent sound quality for TV programming. The bass is there, but isn't booming. For me, that's a good thing. I have one of LG's higher end soundbars with subwoofer and it can be a bit boomy. This one is just right for me. If you are looking for something to play music, you could find something better than this soundbar. Great for TV programming, but not great for audiophile quality music. All in all, I'm very happy.

Very Disappointed

LG S45TR 400-Watt 4.1 Channel Sound Bar I'm so disappointed with this sound bar The rear speakers keep disconnecting I have to do a soft re boot to work When the system is connected its great But what a pain to reset each time you want to watch a movie. truly not recommend this system. I also think LG really cares they will contact me. I have included my email with this review
