i got it 90% figured out and gone....it was the plastic trim ring that site on top of the speaker. i could have removed it from the get go, but i decided not to. now it's gone and there is no more rattle. i also tightened the speaker bolts down more, and that has helped a little too. thanks for the input guys.
