Boxes are stuffed to make the sub act like its in a bigger box.

If it came that way you should leave it in as the designer factored it into his box calculation.

so if my box is of decent size but could be bigger, i should add polyfill? i've never heard of this method..sounds interesting.

In theory yes, but how much bigger? I wouldn't say anymore than .25Ft^3, IF that much, would the sub 'think' there is. I'm not a pro on polyfill, but I'm guessing it can't make THAT much of a difference.

X2 polyfill is not cotton and I wouldn't recommend putting cotton in there.
