Well, all of a sudden, it works! The sub is working and takes the overall sound of the soundbar to the next level! Nice full bottom end makes this a great buy for me. Although it's loud, the sound is focused in the living room. Before, my wife would be telling me to turn the TV down all the time to the point where I could barely enjoy it. Now I can listen at a good level, even with the sub doing what it's doing, and she's not complaining. Excited!
