There seem to be a few other posts in this thread regarding that topic, but thought I would share some measurements to illustrate that the 8341 tweeter can't play full-band content above 90dBSPL//1m. This may be acceptable for music, but our use is for standardized microphone measurements which require sine-wave testing at minimum 94dBSPL//1m.
If 94dB SPL up to 20khz is a requirement for you, none of the Genelec Ones will do that. The tweeter in the 8351B/8361A is good to >100dB up to 9khz, but limits down to about 90dB by 20khz.
IMO this is not relevant for normal use because all music that I know of has much louder content <3khz than >3khz, but it is certainly critical for your use case.
You may want to try the Kali IN-8. If you don't actually need a point source, there are Neumanns, though their tweeters, like many, do drop off in output very sharply above 10khz as well, and few reviewers even bother to test output above 10khz.
