I hope I am not showing my ignorance here...but I feel I am among friends.

I recently purchased new brackets for my front l&r speakers which allow me the flexibility to angle them toward the listening position. As such I thought it a good time to recheck the calibration and adjust the trim level.

My basic question is, at what level should the main volume be when performing the calibration. I have tried various volumes. Average listening level for movies (seems to make sense); zero which was very loud and resulted in trim levels of -10db...I didn't feel comfortable with that; and other random volume settings.

The specs from Outlaw for the 1070 say Volume Range (Main) -70dB to +10.0dB. Therefore would it make sense to calibrate at say -30db or -20db?

I am using a Radio Shack analogy SPL meter.

I look forward to your wisdom.
