Interesting...I'm not trying to be argumentative but test tones for calibrating channel volumes have a wide frequency range do they not? I have always heard that the mic should be pointing up (as opposed to directly at the driver) when calibrating channel volume. Is this correct?

Well, there all you’re doing is setting the relative volume level between the speakers. That’s not the same as trying to measure their response. For level setting, whatever method you use – pointing the meter straight up, or aiming it at each speaker in turn will get the desired result – i.e., all speakers playing at the same volume. The latter method will be a little more cumbersome and time consuming, though...
