Broadband, and bass traps

I am getting ready to make some 6" deep bass traps out of Roxul R60, and some 4" deep Broadband panels from Roxul R80...



I am making the Broadband panels using R80 2" think (doubled to 4" thick), and these will go at my first reflection points on the ceiling, and side walls in my Home Theater.



I am planning on using the Roxul R60 to cover my whole wall (one layer) behind my AT screen. For my back wall I am planning to cover the whole back wall with 2 layers of Roxul R60 3" (6" total thickness). There will be corner bass traps too.





Question: Would it be beneficial to make the front of the panels using pegboard? I am thinking that it adds a little weight, but will strengthen the frame plus reflect some of the high frequencies. I am thinking of this so as to not dampen all of the high frequencies in the room.



All panels will have GOM wrapped over the face of the frame.
