Some speaker driver measurements...

sure, it may look bad on the plot, but is it even audible if you cross it at 3khz to the mid driver?

the vifa ne19vts looks good other then a h3 spike at 7khz, 1% dist at 98db, will this make the driver sound crap and unusable? Vifa NE19VTS-04 | HiFiCompass
That spike will be at 21 kHz. Not audible. Does look like a good tweeter.

The problem with crossing at 3 kHz is that you’ll have a large null off-axis at the crossover frequency due to the relatively high center-to-center spacing. With a lower crossover frequency the null gets smaller.
