There is a long time since I've noted a lower output in one of my tweeters (years perhaps), but never had time to take care of it. I'm talking about AUDAX HD100 textile dome tweeters in my DIY speakers.
They looked like this:
This are the measurements of both tweeters before the treatment: one of them was definitely bad.
Recently, I've found a local speaker factory that sells a "vinyl plasticizer" (google translation for "plastificante vinílico"), that they use to seal textile surrounds. They told me "it stays sticky", so I thought it would be a good material to treat my textile domes.
So, I opened them, cleaned the old material the best I could with isopropyl alcohol, and applied a thin coat of this "vinyl plasticizer". Started with the bad one, just in case something goes wrong, I had a good tweeter to compare.
It looks like this now:
AND, the most important thing, after doing both domes, the pair measures like this:
(I think the colors are swapped, the green line is the yellow line in the previous measurement)
Could it be better? I don't know. But the tweeters came back to life, every sound is clear and crisp again !!! I'm happy with the results, I think I'll try it again after a while, cleaning this coating and doing it again a bit better, perhaps using less material.
