hey guys i picked up a polk audio micropro subwoofer for my home theater system. the newish one with the passive radiator on the bottom. i noticed that the woofer kind of "wobbles" or something when its pumping out bass. like instead of going evenly in and out, the top  of the woofer seems like it might be traveling further than the bottom of the woofer. bottom line, it doesnt move evenly. what do you guys think about this? is something wrong with it, or...?
