Why bother to have them shipped back to you? Once repaired, presumably with a warranty of some sort from Mag, you could arrange to have them drop shipped to your buyer directly from Magnepan, and potentially have the buyer pick up the shipping cost. In fact, there's an old pair of Tympani listed right now, where the seller is doing precisely that- he had the speakers restored, and the buyer can choose the color of the 'grill' cloth and shipping apparentlywill be directly from Magnepan to the buyer.
My only suggestion on the letter is that it be even handed, no hyperbole, facts usually speak louder than characterizations. And ask for his help, rather than dunning him.
