I thought I could fix my Paradigm PDR-10's rumble

Been getting an increasing rumbling sound from my 10 year old sub as its level turned up (not even a third of the way). Came across a 2010forum post of mine in which I had a noise problem with this sub. Opened the back and found some wires dangling. Taped them up and the noise was gone. Figured that I was having the same problem now. Opened the sub and found the tape was unwound and lying on top of the speaker. Retaped the wires, but now still getting the rumbling sound. Is this repairable? And if it is (I naively suspect that the problem is with the speaker cone?), how do I get to work on the speaker as I can't figure how to get to it. Specifically, the grill screen doesn't come off and opening in the back is rather smallish.

The screen comes off. It has tabs on the 4 corners.

I don't know about that. I remember reading that the grill doesn't come off. Also, I did try hard to get it off, but it won't budge. In fact, I did slightly mark the cabinet by trying to pry to grill off???

Can you post a pic? I don't remember what a 10yo PDR10 looks like, but Paradigm shows all the way back to 8 years...it comes off.

The presently broken PDR-10 measures ~14H X 13.5W X 17D. Here are two pics (the flash made the black look grayish):

The grill is different now. The Paradigm logo is part of the cabinet, with the grill going around it. With the amp that big, maybe you do remove the amp, gut it and then remove the driver. Sell it as dead. Somebody around you would probably love a DIY box to build a passive with.
