 You are deluding yourself if you think there aren’t far better modern tweeters available.

  there always was  2 EV tweeters used by klipsch heads ,  the 1st the K-77  , because most middle aged adults cant hear past  12-14 Khz ,   but for the few Boneheads  who can hear past 15000 Hz ,  the 2nd tweeter is the EV-T350 @ 3500 to 23000Hz

I wouldn’t trust any measured differences unless the speakers were both in the exact same position in the room.

 

valid point. if i have the time i'll do the test again.

distance between speaker and mic is 1mtr. what is the preferable height ? i thought to have it centered on the squawker

[ronajon]

i measured the speakers, put them on the same spot with the mic at mid-height of the sqauwker.

first measurement is with left speaker Aerovox caps, and right already modified Monacor.

 

after that i changed the Aerovox on the left with Monacor and compared (old left) Aerovox with (new left) Monacor

 

finally i measured left and right with new Monacor caps

 

here's the diy test setup

 

 

[ronajon]

both speakers are now re-veneered, the front and back repainted with black matte, and put on risers (also black)

 

 

 

 

 

for now this project is finished, only thing left to do is change the Monacor caps to a pair of JEM caps.
