I have two pairs of Heybrook HB2:s, on which the coating /impregnation on all Polydax tweeters have aged and disappeared, so that more than 50% of their surface area lacks impregnation, which is very visible looking through the domes with bright light behind them. An open, sparse silk mesh is all what is left, so not even close to air tight.
I read a thread by diyiggy from 2020, "Poor man silk soft dome liquid impregnation" , where he stated that Audax did use "aqua solvant acrylic coating", and he also considered Polyisobutylene as dope/coating for his silk dome tweeters.
Have anyone found an impregnation fluid that actually works as well as the original, "forever tacky ones" ?
I am desperately searching for one, since the "drop-in" Audax tweeter replacements sold by Falcon Acoustics do not sound even close as good as the original ones.
Best regards,
