Hi everyone

Picked up a pair of DALI Blue 2002 speakers, and I think I may have damaged one of them on my bumpy bike ride back home from the seller. One of the speakers now has a rattling sound, but I don't think the module itself is all broken because it sounds fine if you apply some force on the frame in a certain place.

Hooked the module up to a function generator:

5Hz YouTube
32Hz YouTube

What could cause this sound, and, if possible, how would I go about fixing the module? Thanks in advance!
