I am about to begin the assembly of my N3's. They will have No Rez installed. Because of the top 2 braces I can use poly-fill behind the top mid-woof and behind the tweeter. However, without anything to hold it in place I don't think I can use it in the 2 locations in the bottom.

I have some Armstrong 420 ceiling panels that I used in a pair of Bob Brines speakers I built. Could I just glue the insulation from these on top of the No Res? Would it be too dense? If I were to use the pink fiberglass insulation, how thick should it be? Any other suggestions?

The insolation that I typically use comes in rolls that are at least 6" thick. So you can cut it to size and install it and the pressure of it wanting to expand holds it in place nicely.
