Jeff,

You are correct that there is no universal standard but there seems to be some implied standards that have set by the industry, and the point was not missed. Now as you state in the next topic that the most important thing is to have even speaker calibrations, which I do believe was the message that I clearly stated to you in my PM (although you neglected to include that part in your cut and paste of the topic) even to the point that I said that it did not matter if you calibrated at 75, 85,65 or even 70db. That once you had these levels set that the value you use to calibrate was not really important.
