Looks like tweeter is giving up above 15khz?
Not at all, but they do require a bit of lift to be flat. As this is a prototype thread and early days, you will be subject to less than perfect graphs. In post #19 (immediately above yours), the response is -3dB at 20khz 15 degrees off-axis, which I wouldn't go so far as to call "giving up". An on-axis measurement of that tune would likely be pretty flat to 20khz. Note that these are both responses of a speaker that has yet to be fully tuned, and also indoors measurements done during preliminary tuning, so not very precise.
Our SBS.1 speakers (that use the same coax, and thus the same tweeter) have a flat response on-axis to 20khz, and are about 1.5-2dB down at the reference axis (15 degrees).
