Question

Answer 1

Speakers get damaged in a variety of ways. This noise could be from a cracked voice coil, maybe a worn spider allowing to much slop and the coil is hitting the magnet, a burnt voice coil that is operating ineffectively...

There is a possibility it's not damaged. Maybe it's hitting the speaker grill, maybe it's not mounted securely. Perhaps one of the speakers wires it touching the back of it, or if it's mounted facing up maybe some small object has fallen onto it and it's bouncing around...

Just investigate the speaker and see what it's doing. Maybe remove it and listen to it carefully while playing it at low volume. Gradually increasing the volume while listening.

In the event that it is slightly damaged, one thing I have gotten away with in the past is if the system is accompanied with a separate subwoofer, sometimes you can get away with using a crossover to eliminate the lower frequencies that are going to that speaker. Low frequencies throw the cone around more and generally what cause the most noise from a damaged speaker. Stereo shops sell "passive crossovers" or capacitors that can be wired in series with your speaker. But this all depends on how badly damaged it is, and of course if not accompanied by a woofer it may leave you feeling empty seeing as all of the bass frequencies will have been removed.
