Purple (5) 1016 in straight array
Green (5) piezos on wooden horn

I can't tell which is which.

If my eye are correct, I believe the straight array has the bump at 8.5k.

My eye tells me the same.

I can't tell the colors at all.
Mic calibration file is not used.
Unknown input voltage and measurement distance.
OP, please add some more info.

correct

That response above 10kHz is way low, so something is off with your measurement protocols.

It's a Shure vocal mic (sm or pg 58), not calibrated. I measured a Eminence Delta Pro 8a in a small enclosure and it looks much like Eminence posted, all the way up to 5k. Although, the mic response posted by Shure is far from flat, especially above 2khz.
Anyway, I did the test because I was skeptical of the tweeters actually playing down to 2khz. They do! The wooden horn is to try to get the elements closer. They are 1 7/8" center-to-center and seem to couple better.
By ear, I feel the homemade horn sounds better and a little less harsh with some eq.

Incorrect choice of mic for measurement - far from flat - it has a presence peak
