The graphs i qouted is the more accurate to determine the FR , fig 7 is a spatial avg in room , the mic is not directly into the tweeter, this kind of measurement will always show a rolled off top end, it is not for FR accuracy, it's for spectral balance at the position ....
The FR measurement shows the speaker to be "hot" on the top end ....
