When you go shopping for insulation material for your bass traps, it usually comes in these big rolls or packs, sealed in plastic.

It’s a pretty convenient package!

Why not just leave them as they are and stack them up in the corners?

That will also keep any fibers from flying around and any handling to a minimum.

But does it affect bass absorption because the material is compressed?

Does it maybe even improve things…?

Maybe cutting holes in the plastic is the way to go..?
