Just because  its mil-spec freq response is +/- 1db is  100-3000~ doesn't 
necessarily mean it is limited to that response.  It simply means that it is 
guaranteed to be +/- 1db over that range.  Depending on the manufacturer, it 
may actually have a much wider range.  I have seen military items rated at 
300-3000~  that were actually more like 50-8000~.  A good example is the 
T-368.  The stock audio is very restricted, but if the low level audio is 
redone, the xmtr has good enough iron to sound near broadcast quality.
