Does anyone have experience with the "NOS" Dayton Audio ES104AMT-4 AMT Esoteric Series AMT Tweeter 4 Ohm Dayton Audio ES104AMT-4 AMT Esoteric Series AMT Tweeter 4 Ohm ?
The price has been cut considerably for this limited run (cut to $70), and the frequency response, at least, looks good on paper. There is very little else in the way of specs available, however
Thanks.

My measurements did not show much similarity to the datasheet response at all.
Frequency response attached. Driver is flush mounted to a large baffle, and measured close enough to capture the high frequency response but mostly avoid diffraction effects from the board. The rising response is of similar slope to my AMT3-4 however the response is more extended at both ends of the spectrum. The ES204AMT is a bit smaller than the AMT3-4 so you get wider dispersion as well.
While the response isn't exactly "flat", the slope is fairly consistent so it can still be a very workable driver.
Wiggle around 1.8-2kHz is real, I've included a close up (note the very zoomed in y axis scale) of the impedance as well to show this resonant mode. May not be very audible as it's very short band but it's there nonetheless. Probably best suited to crossover 2kHz or higher.
