vintage Philips domes

[teknofon]

does anybody know the qes and qms of the old Philips AD0160 domes?

I'm trying to remove a peak at 4kHz

Good luck on that one. I dont believe that Philips measured or provided that info. These tweeters are from 1976 and allready then where known for their rather crisp and grating performance (hard plasic dome?). E

All I found is a resonant frequency.....1K Hz., and an RE of 6.7 Ohms. Finding a Qms, Qes will be hard to find as Thiele & Small didn't do their work till '76' or so. One would have to measure the T/S with an existing unit.
