Acoustical Sound Proofing Foam Inside?

So I got bored the other night and for some reason I took a peek inside of my 2 sub boxes. There was an 8"x8"x1" sheet of cotton looking insulation. Is there any benefit to pulling that out and lining the inside of the sub box with that pyramid foam sound proofing? Just wondering if, "the more, the better" applies here? I hear people talking about "tighter bass" with better/more insulation.

I'm bored here at office so I thought I'd ask. Thanks! :thumbsup:

The foam is in there to create added volume of air, making the box's physical smaller yet seeming to have more cubic inches of volume. Each subwoofer has a certain volume of air it requires to work properly.

Ah, so it's not really a matter of "soundproofing" the box. It's there to fool the air "movement"? Did I get that completely wrong or does it make sense? :confused::confused::confused:

If the right amount is in there per the design, the type of material is not going to make a significant difference for a sub IMO.

That is basically true. You could add more or less depending on what sound you want the speaker to achieve. I use to mess around with some of my speakers years ago with insulation.
