All- I go back and forth on this quite a bit likely due to the square nature of my room (20x20x10) and it just dawned on me that when I use the Rat Shack SPL meter to calibrate, I should not worry about the 75db output between the two setting as that is simply a function of the volume setting HOWEVER, is what I should be doing looking at how much the needle moves back and forth within that range? What I mean is the Trim setting that stuck the closest to 75 DB w/o "going back and forth" as much during the test tone would be the best setting right?
Thanks as always guys.
