Hi can anyone tell me where the polyfill is supposed to be placed in the m80? Thanks

behind the woofers and mids is the typical placement of the fill

Ok, I just opened mine last night because when I was moving them to the new room I heard something moving around, what I found was the polyfill at the bottom of the speaker housing along with 3 aluminum "sticks"? "Slats"?

Any ideas? (I posted a pic on the gallery page).
