Somewhere along the way my original instructions regarding the enclosure were changed by some in what I suspect was meant to be a harmless shortcut which actually resulted in a undesirable dimished bass response....Using loose polyfil to stuff the enclosure was never suggested...
That said I...
Yes!! As I just mentioned do not stuff or fill up the chambers! Stuffing the chamber will drastically diminish bass response and increase rattle....Your better off doing nothing than stuffing them!
Conversely, padding the sidewalls with thin polyfill sheet is done to eliminate any destructive...
Yeah, careful with following those youtube videos that tried to deviate from my original writeup as they make some careless mistakes and shortcuts!
Not surprised the rattles are gone after overstuffing the enclosures as you most definetly reduced low bass response!
I just recently posted this reply about a week ago because someone asked the same question
Adding ports is roughly 85% of the solution to the problem!

Over the past 2.5 years of ownership, aside from registration, insurance, and gas, it's really cost me nothing more than that...Keep in mind also had free oil and filter changes and scheduled inspections done over past few years...
Yes, over the past few years since I posted this writeup a few have done the loose fill...I'm not saying it won't make a difference, it's just not optimal for the reasons I mentioned earlier....
In the application I outlined, and as I mentioned earlier, lining the walls is used to reduce destructive wave reflections and woofer dampening effects...
You seem intent on wanting to loosely fill the enclosure, so do it, and see if this works better for you...I will caution you though, that...
