Query: Don't Waste Your Money

I bought these speakers a year and one month ago. To begin with they offered a rebate...I sent all of the requested stuff in for the rebate, but I photocopied everything first (thanks to warnings from others). Yet a few weeks after sending in the required items, I received a postcard stating I did not send in the UPC code. The card gave a email address to respond to if it there was an error, but there was NO PHONE NUMBER TO CALL! I emailed the address and never received any response. They even gave a time limit of when I NEEDED to respond by, yet they did not respond back to me! Needless to say I gave up and enjoyed the use of these speakers...until last week. The amplifier/control unit decided to stop working on the speaker outputs. The headphone jack still works. Of course this is ONE MONTH PAST THE WARRANTY AND THEY WILL NOT REPAIR IT!DO NOT WASTE YOUR MONEY ON THESE!!!!!!!!!!
