First Off, Thanks to everyone for helping and sharing your thoughts.
I want to test these speakers out, as I have never heard them. They where in excellent working order when my father in law moved to England, about 4 years ago!
There is speaker wire hooked up to the screws labeled "input". Can this wire be attached to the outputs of my receiver? Or do I need an amp or anything?
Once I determine their working status, I will list them for sale.
