HiI have been designing horns with THAT paper reduced to mathcad for either case, for about 25 years, for a living.
I have found it to be very good at proportioning driver and horn parameters IF the horn is reasonably large (working close to theory).For situations any distance from an near ideal horn, one must have a way to computer model exactly what ever you have chosen to try.
Do that and DMoore will see what the expansion rate and quarter wavelength mode is and why they matter. You can’t just shrink a bass horn for your convenience and have it still be a bass horn.
Best,Tom
