Lots of garbage on the internet. That stuff does nothing at bass frequencies. It's like it's not even there below several hundred Hertz.
Honestly, no stuffing material works at bass frequencies. It would have to be several meters thick, truly larger than the box. What we're expecting from this stuff is attenuation at midrange frequencies and higher.
So forget about doing anything to modify bass frequencies with stuffing. The stuffing is for higher frequencies. Lower frequencies depend mostly on driver and cabinet tuning.
