I was taking measurements yesterday, trying to evaluate a center channel speaker I bought used.
I set the microphone up on a tripod, aimed the mic directly at the mid and tweet, from approximately 2 feet away.
Pure direct mode on Marantz receiver, -30db volume, graph shows the fundamental at 39.7 db
Used the regular calibration file
At some points in the measurement, it shows up to 189% distortion, with the lowest level at 67.2%
I'm guessing something went wrong with the mic, a measurement from earlier this year, a nearfield measurement of a subwoofer, at 102 db, only measured 3.7% at it's highet point.
Is my mic broken, or something messed up in settings?
