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. Brand new pots from Vintage AR installed. The new pots woke these up and they sound absolutely incredible. 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.
