[Nature Recordists] EM172 capsule frequency response

[Paul <>]

Does anyone know what it is for sure?  I'm about ready to order some from
frogloggers, but I want something with as wide a F.R. as possible.
Particularly, I want/need low frequency and low self noise(one of the thing=
s
I'll be recording is wolves, and want to catch the deep base).  The Primo
datasheet does not seem to spell out the response, but the graphic part of =
the
sheet seems to indicate a pretty limited response of no lower then 100 hz. =
 If
that's the case...are there ANY other affordable low self noise capsules ou=
t
there with a better frequency response?   And if it is the case...does anyo=
ne
have any experience with them, how well they do in the real world with lowe=
r
frequency's?
