So you are saying that the XT32 has many more frequencies that the 14 shown for the manual equalizer. I was under the impression that the XT32 just set the level for the speaker at those 14 frequencies instead of me doing it with REW and my SPL meter. What you are saying is that internally there are more frequency points that the XT32 can use. Now the question for me is whether using the Pro kit would make the XT32 measurements so much better than the supplied calibration mike and it is worth spending the $500 plus license fee to get it.
Find some one in your area with a Pro Kit and spend 150 for a license and have him calibrate your system. I'm in Olympia, WA and I would be happy to do it.
