Hi Curt!

First of all, the membrane gets colder and stiffer. The electronics
is specified at +20 and will behave differently. (Though both will
happen with electrets as well)
Moist is very critical to the polarizing voltage and the impedance
from the capsule itself is at gigaohm level.
The only mic I know which is manufactured for such conditions is the
MKH series.

Of the other mic's, the NT1A is the best I have tested, so far.

Klas.
