You might be able to get your money back!!!
I have to admit, I fell for this a couple of years ago. I spent $200 on the speakers. I talked to the Attorney General in Ohio. One of the reasons they can't shut this down is that they offer a 3 day opt out period. If you can find where they are located, within 3 days, they have to give you your money back. (I don't know if this is true in your state ofr not, but there is probably a similiar law).
I got lucky. The company was DynAudio. I found them through the phone company, drove out that day and got my money back. They did not offer any resistance.
Good Luck!
