Midhorn plans are shown in the links below. They're conical horns, meaning they use straight-sided walls in the horn flare. That makes them relatively easy to build. I'd suggest making a mock-up with cardboard, and then use your cardboard pieces as a template to cut your wood.
You can use either the Delta 10A or Delta 10B, depending on the impedance you desire. We only use 8Ω drivers in any of our models. So our crossovers are designed to use the Delta 10A.
Information about the midrange horn used in our constant-directivity cornerhorns can be found in the following threads:
