 I ALSO need the box to be as BIG as it can (I understand that filling a LOT of polyfill will give this effect, how much do I need to get this effect, as I know that normally 1 pound is recommended for 1 cu ft.)? |
If you need the box to be big, then model it Q=.577. If this gives you the size you're after, you don't want to stuff it, but you do want to line it. Crate foam will work for this. Be aware that this does make your f3 point slightly higher, but you'll get a little more on the low end - a flatter curve.
