First Small true ribbon tweeter with ferrites and a transformer

EDIT : well i made a mistake in the connections of the transformer (connected the ribbon over the wrong wire pair......). impedance was under 0.5 ohm so that why i had 9 db to spare .... when corrected they match those daytons only just no headroom to tweak. i was already so surprised hahah i said multiple times in the video efficiency will be so low. well in the end i was correct :) unfortunately

Since i finally made a transformer i try a small ribbon tweeter. construction (long video) and i play 2 tunes, and some measurements.

Since i could never drive the ribbons directly before this was an interesting build. impedance might be still low.... since my REW setup was fucked... anyhow not a bad result i must say. last thing to do is hunt down the distortion at 10Khz ... not sure where thats coming from yet.
