I also think trying a little more padding on the CD should help, though the easiest way to do it on that crossover would be to put a 15 ohm resistor in parallel with the two 10 ohms that are on the tweeter board. That should knock down the HF level a couple dB's.
It's the PE Dayton mic, I think I left the wrong cal file loaded during those measurements since I noticed the wrong one was loaded the next time I looked at it I picked up another at the PE tent sale (they had them for $16
) so I can compare those two.
Do you have anything USB? I don't have a preamp/interface for XLR.
