To begin fabricating this, I cut out three squares of wafer-board and glued the three together to form a corner. I have had the wafer-board scraps for about 10 years so it is great that I finally found a use for them. Here is the corner with two templates:

Here is what the central core of the horn looks like in its approximate position in the assembly:
|Midrange Central Core In Approximate Position In Corner|
|Side Flare Template In Position On Corner Side Wall|

After cutting eight side flare ribs, I will be ready to attach them to the corner side walls and bend the panels for the side flares that will join the corner side wall with the central core flare pictured above.
At least in theory, I should be able to fit the throat portion of the horn in two vertical halves set into the vertex of the corner. This would be my first horn with two drivers.
