i have a 1.25 cubic sealed enclosure and am picking up some polyfill tomorrow, but i still dont know how to pack polyfill exactly. should i pack it loosely or glue it to the walls of the enclosure? should it go right behind the woofer or what? thanks.

just toss it in there. if your ambitious enough, tack it to the back wall.

i always glue it to the walls of the box, using spray on glue.

Use about a pound per cubic feet and make a little nest for the magnet to cool off. You do not want that stuff getting around the spider or any moving parts or parts that need to be cool.

what size sealed enclosure does your sub require?

its a 12" avalanche, figured i try some polyfill since its so cheap, see if i can get even more low end out of it. i know the reccomended sizes for the ava, but i see some people running them in 1.5 ft^3 sealed, so why not give it a shot.

in the pictures ive seen it looks like insulation/cotton candy, seems like it would just fall apart if i tried to glue it to the inside wall, is this true? what brand should i get if i want to glue it to the wall?
