I have inherited 4 Klipsch speakers. One pair are Heresy in perfect condition. The other pair does not state the model. They are probably both at least 20 years old. Heresy are in Perfect condition top to bottom. The other pair are in great condition except a little fade on top of each speaker - needs a good oiling. I have no idea what the value of these are, but if somebody can tell me what to sell them for that is a fair price, I would appreciate it. Chicago area location. Local pick-ups only.
