bass trap normal insolation

I'm going to make some bass traps. My question is will normal fiberglass insolation work as well as mineral wool or oc 703?
None of the hardware stores around where I live carry mineral wool or oc 703 and I have a few bags of R25 pink insolation kicken around.

Any help would be greatly apreciated

You can use fluffy insulation but it needs to be squeezed to be about 1/3 or 1/4 as thick. So buy R38 (12 inches thick) and squash it down to three or four inches thick to make it similar to 703. Getting it to keep its shape is not easy though.

Or, you can use it as-is with less density but a lot more thickness if you have the space for it.
