Speaker rattle on 520c

[worldofJCK]

Hello all, 

I’ve had this PowerBook 520c for a while now. It’s in quite good shape overall but one thing continues to stand out: the right speaker makes a very interesting rattling sound when playing pretty much any audio. 
 

Hopefully this can be discerned in the attached video. Is this a problem anyone has encountered before with a simple fix? Or something more fundamental that would require the replacement of the speaker? 
 

I am a bit of a novice but more than willing to take things all apart if necessary. Let me know if anyone has any ideas.

Could be a blown diaphragm. Most likely it's a busted screw mount though. Either way you'd have to open the display to check.

could be debris stuck to the cone/magnet as well. Anything is possible.

Thanks all, sounds like the first step is to just see if anything looks obviously out of place. If I get around to it this week I’ll open up the display and take a peek.
