I designed one, but it's really too large for home hifi use. Especially since corner placement allows for a much smaller horn to be used. That's the direction I went with the midhorn - It is used on my constant directivity cornerhorns, and its output blends with the woofer in the 100Hz to 200Hz range, smoothing room modes in that band.

Any thickness adds to the front chamber volume, but the amount is slight unless the panel is really thick. Still, you don't need much. So limit it to 3/4". Sizes from 1/2" to 3/4" are fine.

Just the flare. The rest is kind of easy and probably wouldn't meric the cost. But the flare angles make it attractive for some to buy the flatpack kit. As horns go, it's as easy as it gets, but still, there are some angles to cut. I recommend starting off doing a mockup in cardboard for people that want to cut their own.
