Some have metal diaphragms most have nonmetallic possibly plastic and the early ones seem to have paper. These are the ones that interest me. Searching but not one forum post about sound quality. In English anyway. Can anyone help? I am tempted to buy a pair. I looking for a warm tone. Someone said there good for 600 to 12k someone said 1k to 12k. Lots showing up on the Russian Ukrainian ebay markets cheap.

I'm not sure which diaphragms did we measured , but they were flat and OK' from 1770hz to 15-16khz.

Thanks for your reply .Yes they are factory rated for 16k I was mistaken. Did you test them for sound quality? Did you test them on horns?

[grec13]

yes.
in standard aluminum horns that they should use. throat and everything else looks similar as a TAD.
they have a peak around 1700hz, but otherwise is pretty flat. No that much 'air'. about sound quality -is hard to say now. Was 5 years ago. It was not bad at all, but was not something remarkable also. considering the price -they worse it. huge alnico. you can play with diaphragms. I use to have 50 of them brand new. that's the only driver which is interesting from all Kinap.
