These were originally purchased for a project I built that never turned out. Some were installed and hooked up to amplifiers and tested, others may not have been. None of them were ever used regularly and all have very little actual usage other than testing. They have been floating around my shop in various containers for the last 6 or 8 years. Visually not Prestine, although nothing really wrong with them either. Each has been hooked to an amp and tested before listening.
