Thanks Ethan for your helpsince i was planing to bulid the one in your plans so 100 is the most
in this case 4" bad panel would provide more absotion in bass and mid area. I plan to build these panels do you think the fiber should touch the panel like the original or if i leave some space could help absortion in the bass(would it be a helmuzt in a way) it would have a frame
sorry Kal for the link the corret one for the 4" is:

It depends on how it's mounted.

Build which, membrane traps from my plans or a knock-off off the RPG panel? If you build from my plans there has to be a space. If you mean a BAD panel, I've never seen one so I don't know what's in it besides rigid fiberglass.
Both links compare BAD panels of 1",2",3" and 4" thickness with Fiberglass of 1" thickness and that is what I think is misleading. The difference between the BAD panel and FG is in the 1KHz and up range as the low end is the responsibility of the FG in each.
