Post Subject: Throat size:formulaPosted by chaos on: 7/2/2008
jezzie i used this formular for throatsize:
St=2PIxFSxQesXVas/c
i, m very close, my horn is just 2" shorter.it would not be a big problem to make it longer, but in my small room every inch counts.on the other side, if somebody with experience tells me.....i´m here to learn!
my other tought was:
a typical 15" has a sd of around 130sqinches, increase the dia. 0,5 inches and you get 140something.
9,9" give an st of 77, which is rougly 55% of sd. i read your post to guy and thougt, my throat will be even smaller than romy´s and yours.
its bigger than yours, this i can see right now, yours and romys st is 45%!
i will make a compromis and stay with the formular;-)))
very strange do calculate things for me, unit conversion takes time and i have no feeling for the american units....
diaphragma
ic will follow!
this is exactly what i plan
tart with a solid foundation and leave room for improvement!
