Curvy Chang plans

I bought a pair of FE207E new in 2006 when I moved into my very first apartment! I ended up building an 8 foot tall folded voigt pipe. They sounded great and I used them all through college until I moved to an apartment where they would not fit. I happily remember seeing plans for the curvy chang in the past and I am now at a point in my life where I have time/money/wood to build them. I kept the drivers in a box all these years waiting to build a set of Curvy Chang. Unfortunately I am failing at finding any plans for these boxes. Been searching the internets and this forum for a while. I swear there was a very long thread for Curvy Chang with plans, but alas I can no longer find it.

Any help would be great.

Thank you.

These plans were made “by request” since all the drivers are NLA.

PS: i still have a few phase plugs for these drivers. There are also some fairly simple tweaks tht improve the driver
