It has a bit of a peak bump that I don’t like but in the next screenshot I post you will see a matching peak and RMS curve and no peak bump anywhere.
Manual,
I forgot to grab a screenshot this morning with the pink noise CD in but here is one from a week or two ago prior to the additional tweeters.

Still chasing it but I am really close.
Manual and anyone else interested,
Here is the youtube link, , as recorded on an iPad. It still does not fully represent the sound and clarity of the system. Ran down this evening and recorded another 9 minutes or so with the iPad exactly where it sits during set-up and boy was that a mistake. The response was flat which probably had to do with the iPad mic being shrouded. The only way I am going to get a better representation is to buy a good mic and rerecord. Nah, I have better things to spend money on.
