Does anyone have more info about these tweeters? Primarily what is their sensitivity and usual crossover point.
I know they had been used in some notable speakers like Telefunken TL800 and Dahlquist DQ10.

Since I have 4 pairs of HTL1913 lying around I was thinking to use them as replacement for few Grundig broken boxes I have (306M, 416).
(I have few defective Grundig tweeters but repair is 70eur/pair, and for some boxes it just isn't worth it)

Question is.. are they good, would it work, is there big sensitivity mismatch?

Found some info.. 19mm dome, excellent linearity over 1500hz up to 20khz. It might just work out fine.

I finally got some time to do proper measurements of this tweeter.
I will post it here if anyone will find it useful.(together with grundig tweeter from 450a).
Measurements were taken from 70cm distance on baffle 1x0.5m in open space.

Thank you for your contribution!

Thanks! It should be noted that grundig had cleanest waterfall and harmonic distortion content i've seen. Better than modern esoteric cordonum and ceramic tweeters. MB had 2nd harmonic distortion peak at 7khz and medium level resonances above 10khz. Also grundig tweeter was not flush mounted. That explains some bumps in measurements.
