Thanks...I went ahead and bought them....it quite good shape.....both woofers need reform...mid's have been reformed recently. I have not opened the tweeter grill yet to look in. Paid $185 delivered to my Jeep. I was amazed how heavy they were for their size when I had to unload them. I can say that McIntosh made these cabinets to last years! I think I did okay...My son might like these ...with a Mac amp and pre amp.....
I'll reach out to Roger in the coming weeks when I am free to jump into this project. I also found the correct links to the specs....I apologize for listing them as MC 1A's ....this was the error of the Estate Sale,,,they are clearly marked ML 1C on the back....LOL
