In the front rear and dining area positions the traps were between 2 and 3 feet from the wall. I did this on purpose to get the maximum absorbtion from the panel (closest to 1/4 wave points, and at maximum sound wave velocity).

I can permenantly install the traps at the front location with the front of the trap at 22" from the wall, pretty much where they were for the test.

I am specifically interested in how much of a difference thickness will make at a given location.
