So nearly all electrets and SDCs have the diaphragm connected to the body or outer shell.
yes, I stated this wrongly in my OP, assuming that it was the backplate that was connected to the outer shell.
It makes no difference to the main issue though.
Since a typical electret has an effective polarization of over 100V
I had wondered what level of polarisation electrets had, that explains why some are more sensitive than I had expected.
the objective for many mic hobbyists is adding new "flavors" of mics to your recording arsenal, so keep experimenting.
That is indeed my objective. Although I already have quite a few flavours the available parts tend to push one towards certain well-trodden paths. I'm now trying to diversify the sounds available, without actually increasing the (very large) number of finished mics I have.
I've yet to hear an electret that really excited me, although some are very functional and useful.
I wish there were more larger sized pure pressure (omni) capsules around, and more small capsules that don't have a built in fet and that can easily be mounted without grounding.
The one exception is a 35mm electret made a few years ago with metal diaphragm and K67 backplate
hmm what was this, are they still available?
