I'm trying to built an L200B with a JBL 077. I bought 2 pairs of LE85 one for a friend and one for me. One pair came from a fellow here in the forum, awesome person to deal with, thank you Miller. The other LE85 pair bought from Ebay from CPsound, posted one JBL85 real nice with horns and the other he said it was in the same condition, same with the crossovers. I end up with one JBL LE85 with red seals intact and real nice and the other no seals but nice and it look like they try to open as there was tiny paint missing around the holes. Anyway I opened and the diaphragm looks to be original, my question is are there aftermarket that look the same as the original. I also found the back foam deteriorating, so I can assume the other one is also, do I need to replace it to achieve better sound. Also both N200B had like sand inside, and they look slightly different one has the cables going out through the top and the other through the front. I freak out and ask if the speakers were at the beach or something, because both had like sand coming out. Do you know if JBL put like sand type inside the crossovers. Nothing changes in Ebay there is always an astute trying to cheat others, and when you are exited you forget to ask questions.
