Default looking for help with find plans for Tractrix Horn to suite Lowthers

i have been looking forever on the net to find suitable tractrix horn plans.
I suppose i like the Oris front loaded horns but wish to make that in DIY and in square format.

I am unable to use programs to work out what i need
I am hoping to build in timber

i already have suitable sub woofer

can some one point me to where some diy plans are to be found on the net.

Ken...I build horns...and I'm in Oz...Sydney.

One tractrix horn is the Carfrae Little Big Horn. I have a license from Jim Carfrae to build this. DIY/flat-pack kits available.

You're talking about building a front loaded horn in square format.
What size throat and what low frequency cutoff do you need?

I might be able to plot something out.
