Heh. I got the MM-1's to IMPROVE the low end. And they do just that relat=
ive
to the preamps on my Korg MR-1000. My Avenson STO-2's are still a little l=
ight
in the low end in general, plus high in the noise floor. I also got the MM=
-1's
to improve battery life by moving the phantom power burden off the field
recorder. And they do just that. 2.5 hours on fully and freshly charged N=
iMH
batts for the Korg by itself. 2 hours or less if the batts were charged a =
week
ago and left in the off field recorder. With the MM-1's, in addition to th=

Korg, I've done 4 hours continuous and the field recorder still showed 50% =

the meter. Which takes about 30 minutes to go past with just the field rec=

and phantom powered STO-2's.
EQ is your friend. Not really doable at those frequencies live though. Ba=
ring
some DIY and other custom electronics. You also need a monitoring environm=
ent
capable of producing those tones to hear what you recorded. Otherwise you =
might
need to double the speed or more to bring those frequencies up to the
reproducable range depending on your gear. Audacity has some tools to anal=
yze
and filter and EQ.
Even if your headphones are spec'd to 5Hz, they probably don't actually pro=
duce
that. And wind noise and other things can be in that range, so there's not=
much
proofness in such content. Although using that range as a location detecto=
r
might be interesting. Those lower frequencies don't travel as well over
distance in air. Visions of indians with their ear to the ground come to m=
ind.
I guess I should have done more school. It's feasible to make a locator wi=
th
three points in contact with the ground. Strength and timing to each senso=
r
(mic) to determine a direction. Much like earthquakes and the use of three=
points to determine the epicenter. I'm not sure how useful it'd be without=
hard
data to single out the subject from deer, bear, squirrel, wolf, wildcat, mo=
ose,
and whatever other critters. It's a noisy world out there. And you'd only=
be
able to detect when the subject was moving. And trying to find / catch up =
with
a moving
target might be an exercise in futility.
I've had SM81's that were decent on the low end. No measurements though. =
Just
a hankering for some Tuba. An old AT4033a was pretty sweet on the low side=
. A
current AT3035 that is okay down low. Noticeably better than my STO-2's. =
None
of which I'd want to use outdoors since wind proofing them would be near
impossible. Plus you need some decent shock mounts or it's all handling no=
ise.
Special cables and other things to further isolate them from the rigging. =
Good
luck with that as that range is probably the most difficult to do well. I'=
ve
been longing for some MKH8020's which spec okay down there according to the=
manufacturer anyway. But not cheap, and not the most favored of the not ch=

mics.
