I have a polk audio RM6000 setup. I am now noticing hearing something rattle inside the sub sometimes even at lower levels. Its the powered sub and i have it turned up half way.

Any ideas whats going on?

Is it like something is loose or voice coil chattering?

Must be voice coil because when i hold my thumbs on the outer edge of the cone the rattling stops.
