Poly-Fil stuffing for sub boxs i was wondering if this stuff really works

Poly-fil stuffing

i dont know it sounds like one of those fake products to make u think it peforms better in actualy it does little to nothing. just let me know if u think it would work your personal oppion on the product if u have used it tell me if u like it and would recomend it

when i used to build home audio i'd put r-12 which is just fiberglass insulation to help kill the resonance, so it's possible

ya that is how it works

you dont need that stuff btw, all it is is polyester stuffing (pillow stuffing) that you can get at walmart for like 3-4 bucks for a big bag

It works well if you dont have a big enough box for the sub your using. Otherwise if you have the right amount of airspace in your box, dont worry about it.
