Huh? You changed the horn orientation to vertical? It's not a line source, that will give poor horizontal dispersion and more reflection. I'm sure it's a fun experiment but I think if you want a time aligned speaker buy one, Paul is groaning. Not completely true. My 1973 Cornwalls have both the horns in a vertical arrangement. They are also mirror images of each other. Some say that these image better than later models. Left speaker:

In fact, the Electro Voice T-35 tweeter (same as Klipsch K-77) DOES behave like a line source. EV specifically recommends vertical installation to avoid floor reflections. The dispersion is wider (side to side) when mounted vertically and wider (top to bottom) when mounted horizontally.
As to "top of the box" reflections, please note that the original photo, on post 1 of this thread, has his tweeter mounted not much farther than mine above the top of the box. Further, his tweeter is more "square" than mine, which means MORE dispersion vertically. I could stick another box below the one I've got, but I doubt that it would matter much. If you think it would, then I'll try it too.
I also tried putting the piezo tweeters in with the K-77s. MUCH too bright. Just for fun, I tried turning the piezo tweeters toward the back wall for some "bidirectional" sound. Still too bright. No piezo for me, thanks.
Ultimately, what I may do is mount the K-77s vertically inside the existing box, and on the front of the motorboard. If the boss is comfy, at some time in the future, I may just cut the tops off the existing boxes & make a "commando, steam-punk" style speaker with fully-exposed midrange and (time-aligned) tweeter horns. That way, there would no be no major surface for the tweeter to reflect from.
Enough experimenting for now - I'll just go enjoy the music!
