2307 (H91) inner profile shape

[ratitifb]

Hi folks,

does anybody know where we can find the inner profile curve of the 2307 horn (equations or drawings)?

or does anybody have only one 2307 for sale (at low cost for the science:p) in order to measure it by resin/silicon mold or profile measurements after cutout ?

Thanks in advance for ;)

I did that long ago in a spreadsheet, to compare the 2311 2307 and
some other custom stuff (knock off 2307's being cut up for 1.5" duty, IIRC)
that was being put together by another member...

I'll check later to see if I still have it. Or you might beat me using search.

I don't have the spreadsheet, but it shouldn't be difficult to figure out.
