What do you fill an enclosure with?

I have a fiberglass enclosure that is housing a Boston Pro 12.5 that I need to get down to the recommended 1 cubic ft. Right now I'm about .25 over. It may be nit-picking but it bugs me nonetheless. All recommendations are appreciated and welcome.

you could use that expandable foam if you can keep it under control. it does make a mess if you use too much but you can trim it after it sets up.

Just make a 0.25 cuft MDF box (based on external dimensions, not internal), and glue it inside the fiberglass enclosure.

depending on how much you need if you can add some extra bracing it helps in more ways then one.

That did the trick. Thanks Eric.
