Default Folding Horns - Hornresp to 3D. Throat chamber

Hello,

I have designed at horn for an RCF 12" low freq driver in hornresp. I exported the horn data and translated it into Autodesk Maya 3D software. This is not a engineering modeling tool.

I have folded the horn but how do I design the throat chamber? Where does the speaker baffle go? and how should the speaker be mounted to the throat chamber. How do I calculate the throat chamber?

I tried to use the Hornresp "Throat Adapter Designer" but had some confusion in the width set for the horn . Can anyone help me visualize where I might mount the driver in relation to producing the desired output.

The S2-S4 is a Uni fold. The Small S1 is a Con.


Thanks in advance. All the best.

The horn profile is chopped and in different colours to visualize it. The box is designed loosely in 3D. I am hoping to draw the final in Sketchup.

I am stuck on the speaker mounting and throat chamber. Any help much appreciated.

I have changed the fold. Model is to scale but not accurately modeled until I move to Sketchup.
