Ok, I'm documenting my venture inside one of these things to get to the damaged cone (actually two, one of the mid ranges has a little tear, nothing to fuss about). Here is the back of them. As you can see one of them is missing the speaker wire terminals. Ok, now time to open up the back of one. The back is one solid piece held on by screws. To be honest, I was afraid a small wild animal was going to jump out at me when I finally went to pull the back panel off... Anyways, first look inside: Ok that's all for now. Going to go get back into them.
