I agree with you that using the second microphone tends to confirm the original measurements. The trend shows in both measurements. The second microphone isn't as flat, but the trend is still evident. I would consider this to be corroboration and it gives me more confidence in the tests, or at least in the microphone. I'm still not 100% confident the rolloff isn't from something else besides the compression driver and/or crossover, but I'm becoming more convinced that it is.
It will be intersting to see the measurements sans crossover. That will narrow this down further.
