This is my first post in gearslutz, after reading the forums for a while
I was gonna build some bass traps this weekend, almost exactly the same way, except I didn't even plan to use chickenwire, but just use burlap and staple it really tight.
On your 2x4 panels, do you have enough strength in the middle, or should I maybe add 1 or 2 boards for additional support (so the 4' boards don't get pulled to the inside too much) ?
