Subbox Fill material

[ace5high 10+ year member]

I Need to take up about .2 cu ft out of a box thats too big. What can I use just to fill up space in a box without adding too much weight?

Ive heard that hard styrofoam will work but I cant seem to find any around here...

polyfill

polyfil will not have the desired affect. You should just make a partition/ divider out of mdf. But unless you are running a box

I agree with dkmesa. What is the current and desired size, and why do you want to reduce it?

Im trying to reduce it cause its too big for my current sub, when I get a new Sub I plan on using the size it has now. But in the meanwhile I need to reduce it a little bit to my liking

Oh and its a 10" going into a .6 cube box, Id like it to be about .4 right now with this sub, need something I can remove later
