hmmm.. I thought that was exactly what I just said.
zero is used for reference calibration
edit: Each speaker is calibrated to 75 or 85db(dependent on your manual) with SPL meter with the volume set to 0db running test tones. This is how I understood it was done.
Obviously with a real signal through the system you could be over 100db with the dial at 0db.
