I would check the price of replacement ribbons; you would probably have to buy 2 , a good idea anyway. There are several repair stations around the country; Northern Va. for one; I would not want just anyone working on them. It would cost quite a bit to get a comparable replacement today. You have to decide how much you like them on the basis of listening to one. Two repaired speakers should sound very good. Gratz is the name of the company that makes replacement ribbons. I would go the the Apogee site; it was still going this Spring when I was repairing my Duetta Sigs.
I had a pair of Slant 6s. They are great speakers. There are few speakers that have a following like Apogees so long after they were discontinued.
thank you for your answer,and Gratz ribbon replacements for apogee, by the way you have an incredible system
