Sub Possibly Blown?

[Orion Man 10+ year member]

Hey guys, I have a pair of Polk/MOMO MM2104 subs. One of them started making a rattling noise when running at higher volume. Gain on the amp is roughly 1/2-way.

I pulled both subs out and checked them. Couldn't see anything. So, I hooked them up individually and only 1 of them is doing it.

Anyone have any clues? Its really annoying and I have noticed that I don't have as much low-end since it started.

Any help would be great!

I actually did that. It makes a "thunk" when you push the cone in?
