I went from 1st calibration session in which it set the level for each tower at 75%. Now, this is with the older titanium tweets and Morel drivers and that sensitivity was suppose to be 91db at initial build. I thought hmmm, i've never had my receiver ever set anything up that strong and the output was not blow you out of the water crazy loud either. After the first 40hrs and a 2nd calibration, the signal dropped to about 45% from 75% and it was night and day, huge difference. Beit I never ran pink noise, white noise or anything crazy through them and the titanium tweets were supposedly already broke in and matched. Output was louder and of course the definition was huge.
