My 500 also developed a rattle in both the driver and strangely
the amp. Axiom replaced both, GREAT folks and service!
With the amp I could actually tap the back plate lightly with my
finger and the amp would vibrate. The driver cone was separating
from the outside ring.

Bottom line is, if you have any problem/question...call Axiom.
