Default Help with speaker repair

I was hoping to get some thoughts on what might be wrong with my speaker's tweeter. I've attached a summary of nearfield measurements I've done on my good speaker, the bad speaker and the bad speaker after I opened it.

The bad speaker had an indention in the wire mesh covering the tweeter after a recent move. Thinking this might have something to do with it, I opened the speaker to pop it back out. However, as you can see, in the process of opening it, I did something to further damage the speaker. Any thoughts on what the issue is? I can post pics of the speaker and internals, provide more info, etc, if needed, but I'm not sure where to start at this point.

Any chance you reversed the wires on the bad tweeter? Try that first.

Maybe you didn't place the voice coil in the gap the right way.
What tweeter is that?

Hmmm..., sounds like he just straightened the mesh, not the tweeter itself of I might have guessed the damping pad in behind the dome.

I'm not sure the exact tweeter on my Usher S-520, but it's one of these: Usher - Replacement Speakers, Bass Speakers, Raw Speakers, Woofers, Tweeters, Midranges, Dome Tweeters, Dome Midranges, DIY Speakers

I pulled it back out and put it back together to make sure it was re-assembled correctly, but I didn't see anything. If I remember correctly, the dome (the small piece of plastic/rubber, right?) was a little indented, as well, when I first pulled it out, but I popped that back out, as well. I took some pictures on my phone when I pulled it out and will put them up in just a second.

Double check everything!
E.g. put the speaker you may have damaged in the good box and vice versa, and re-measure.

For some reason, I keep getting security token messages when I post the pictures. I'll try that again later.

As far as swapping the boxes, I would like to, but I'm not sure how to remove the wiring running to the speakers. For lack of a better term, they're sealed onto the speakers. I'll post pictures later and maybe someone can guide me through doing that.

By the way, what part of MD are you in? I'm between Baltimore and Annapolis.

After logging in/out, I'm still getting the same message, but you should be able to view them here:
