I'm sorry you are having problems with your speakers. You mentioned that they are only 6 months old. If you would like to send them in for us to take a look at them, we can issue a return authorization number for you. If you can provide a copy of the purchase receipt showing they are less than a year old, we can cover the repair under warranty for you. All you need to do is contact customer service at (800) 843-8823 with your model and serial number and they can issue you an RA number.
