What People Are Saying

Rated 5 out of 5 by from Fantastic! Bought this about two months ago absolutely no regrets bass hits hard mids and highs very clear as well and nothing is muffled out at any volume on this. Talk of the party and all my friends are looking into getting one of these or a similar lg speaker system. Bluetooth connects very easily and does not need to be powered on when connecting to it.

Rated 5 out of 5 by from Exponetial Audio System I have reviewed everything in this manual from beginning to end. I have never seen an audio system with so many options. It's definitely got everything you could possibly wish for in an audio system. C'mon 3500 watts max output. You'll definitely be in the professional arena. The LG name behind it your talking lasting quality.Remote control offers every option. I've had two different model LG phones. Both phones were of excellent quality. I know anything else they make would be of this professional quality!

This unit only has an FM tuner that has am FM tuning range of 87.5 to 108.0 MHz or 87.50 to 108.00 MHz. It does not have an AM Tuner. The specs are incorrect and we apologize for the error. Thank you for pointing that out and we have passed the information over to be corrected. ^AC

The LG Bluetooth Remote app is a Bluetooth remote control integrated launcher application that can control media products, released since 2012, connectable to Bluetooth. It can be downloaded from the Google Play Store or the iTunes App Store.
