Most of the time horn resonances from the recording horn result in a
noticible bump in level at that frequency and at multiples of it to a
lesser degree.  One of the first devices marketed to EQ these out was
the Owl 1 and the Owl Multifilter, designed by Tom Owens.  The Owl 1 had
a notch filter which you would sweep up and down in a boost position
that would greatly exaggerate the resonance, and then you would reduce
it at that frequency till it sounded more natural.  But you can do it
with a parametric EQ, especially if you can also vary the bandwidth of
the de-emphesis as well as the frequency.  Tom Stockham at Soundstream
took this a great deal further with a digital system of finding the
multiple resonances and reducing all of them -- sometimes hundreds.  He
also shaped the curve using electrical recordings of the same or similar
voices, and this is where it becomes controversal, making Caruso sound
like Bourling.

For acoustic recordings, there is no eq curve.

Beyond that, it would be interesting to compare results of eq appiled to

various types of cylinder and disc transfer when adjuted to a flatish
line 
as guided
by a spectrum analyzer, keeping in mind the frequency limitations of the

original medium- i.e., don't dispair if nothing but noise comes up at
9K.
