They have been re-foamed. Although they are close serial #’s the cabinets do vary especially in the front and back. Serial #’s 76558 & 76822. The owner put the extra fuse block on for added protection and ease of connecting. They sound incredible, but the pots are touchy and will need to be cleaned or replaced. As with all of these at this age. But with a little messing around and jiggling them, and all the drivers play as they should and have been for the last 4 hours. PLEASE look at all the pictures, they are beautiful. These also have all the original untouched crossovers and internal wiring. One of the finest untouched original pairs I have ever come across. All the original paperwork is also included. Chasrock Services is proud to be. (ISTA 6-FEDEX_A Protocol Certified). This is a registered certification in electronic packaging. They put that package through rigorous testing including the following. Shock Test: (10 random drops from 30 Inches). Compression Test: The package is then tested in a press at 976.94 lbs. Vibration Test: The package is then put on a vibration table and violently shaken for 45 minutes. You must pass all three tests without any damage, cosmetically or functionality. I think it’s worth a few extra bucks, because they can’t be replaced. Pride myself on extreme over protective packaging. Please see my feedback! If you need more time, just send a message and we will work something out.
