I know nothing about electronics or sound, these were given to me by my Uncle about 7 years ago when he decided to upgrade and I was moving out. I hardly ever used them and needless to say they belong with someone who can enjoy their quality. My question is, I want to sell them on Craig'sList opr some where but dont know how much to ask. Im not sure if they work as I havent set them up in about 3 years. Was thinking $500 for the pair? Any suggestions?
