Seems like a "no holds barred" rearhorn, but not terribly practical.

If I had a pair of FE206E and wanted to build a rearhorn, I would:
(1) Build the Dallas II horn. It is optimized for the driver.
(2) Do the Decware phase plug mod. I've done it for my FE207E and it really smooths out highs.

The plug is simply a 15/16" socket (3/8" drive), standard length. Find the closest equivalent in metric, should work fine. Below is a drawing that I believe is proper scale. You need to remove the dustcap, careful work with a hobby knife works fine. When putting in the socket, grab tightly, it really goes for that magnet. As you can see in the drawing, the small hole (i.e. wrench side) goes out. Once it's grabbed the magnet, use a screwdriver in the hole (careful) to center the socket.

I was very reluctant to cut my drivers, but am very pleased with the end result. Also, the chrome actually goes quite well, visually, with the driver. Tell your friends that it's a concentric tweeter.

Thank You for Your explanation
I know about Your phase plugs planet10, and i have two similar that i've made it for experimenting with my fullrange Visaton BG20
This is my project for folding voigt pipes with these speakers...
But i really think that decware mod is better because of "floating" sound waves below their mod. I think that Your phase plugs are art, but they make sound more directing to the listener and in consequence of this driver acquire more sensitive for moving on axis... even in 30 degree.

I wouldn't take the DecWare write-up at its word. I think it functions pretty much the same as any phase plug: filling that space void. It just happens to be very simple to implement, which was the reason I did it.

Steve is pretty good at spinning things. In my mind, the most important role of the phase plug is to fill the hole after you remove the dustcap.

Yup.

BTW apologies for the redundant "space void".
