Hi Wayne, In your writeup for 12 & 15 Pi horns you mentioned a conical horn for 15" driver. I've been thinking about this for a while. How large of mouth is required to get down to 100-125 hz range? Can mouth be minimized any when cornered using walls to extend mouth? Could you run up to say a 1.6K xover point with something like a 2226? Considering a folded bass horn up to conical horn, then compression driven horn up top. Thanks for any thoughts, Jerrod P.S. Finishing drywall in music room now, getting close to kicking off major speaker building projects!

Hi Wayne, Began modeling in hornresp, I started by figuring the throat area at 6 3/4 x 6 3/4 based on the 15" size, relative to 4 1/2 x 4 1/2 for a 10" driver. I set the mouth size for a 30" x 15" horn. I wasn't sure how to set VTC and ATC. ATC I made equal to SD(?) How do you figure VTC? I need a McBean for Dummies book. Thanks, Jerrod

You might be interested in the midhorn I did with a 10" driver. It covers nearly the range you're wanting, shifted about an octave up on each side. But if that will work for you, it will get you going right away. It's been tested and its performance is documented so you can know what to expect from it.Or maybe scale it up for a larger driver. I'm fairly confident it would work pretty well, at least put you in the ballpark. Maybe you would enjoy making one and giving it a listen.
