looking for someone that may have used this tweet. There is a resonance at 30khz in the spec sheet. Do I need to put a notch filter on it or just ignore it as it is out of hearing range....

ha ha yea I thought by some chance there may have been some "trickle down" effects from what was going on at 30k that might be audible in the hearing range. Thanks
Worth looking at the SB26CDC, seems to be a similar design but with less break up but possibly a little sooner.

Ben (wolf_teeth here on diyaudio) has a lot of measurement information on the H1825 tweeters: https://diy.midwestaudio.club/discu...-gb-some-facts-some-opinions-and-some-data/p1. His crossover has notches for both Fs compensation and the ultrasonic break up.
Digital sources will cut off at 20k, and, despite much 'creative' advertising, most phono cartridges have responses past 20k
that do not so much droop, as plummet.
So, as WOT says, watch the dog(s).
