I'm a little lost, since I've never looked inside of mine. How did you see this? Just by looking inside of the port? Did you use a flashlight and a mirror or something? or did you take the tweeter out?
Just by looking. I compared the new one I got with the older ones I received first. I wasn't really looking for anything, as I was fooling around with my speakers and I saw that rear "hole" LOL just thought why not take a look inside? So when I did, could see some loose wires. To have a confirmation that this was a standard thing on the speakers decided to do a A/B comparison, realizing that there was something wrong with it.
