Hi
Yes i did, it was the 511. I did change a couple things other than to the 4550 and 2226 drivers.
There was a spot on the back side of the vertical flare in front of the flat flange that had "sensitive" spot i put some damping material on.
There was a spot mid point on the woofer flare that had a resonance where i glued a brace to the outer cabinet wall. The baffle at the bottom (bare plywood in the picture elsewhere) for the woofer port was added after measuring the box sealed (i didn't want to try and calculate the volume when i can measure it's effect).
When trying to work out a crossover, i found if i moved the horn back an inch and a half, could get a Synergy style crossover with very little or no XO phase shift.
This was a long time ago, i don't have a measurement file in the folder for it but i know i did once haha. Red scale is phase, + - 180 degrees scale. Crossover is about the center left to right
