Have a question. I have a pair of crewing vega D 7E speakers. That were purchased in the late 1980s. For about 2000. Have not used them in over 10 years. Someone is looking to purchase and asked me for a price. Told me something about the orange foam likely needs replacing. Not looking to make a fortune but also do not want to get taken for a ride. Can anyone give me a rough idea of what I should ask the guy for them?
