Yeah! I like the capo trick; thought of that for those songs with the annoying modulation that takes nice jangly open chords into all barre. Thought of it; realize I'd never make it happen musically. Nice to see someone can. Some songs modulate and yet remain within the bounds of what I can actually fret.

At 67, still working on trying to render songs into a recognizable form at all. "Raindrops keep fallin on my head" is one of the latest. Lately enamored with how certain chord changes flow; if / when I can get into flow-state with it that is. A fellow did "Jamaica Farewell" the other night; I liked the chord changes in that one!

I do recall @nc535 running several simulations with planar tweeters and separate tweeters too if I recall it correctly. Been browsing that thread and didn't find what I was looking for:
Here's a planar simulation: https://www.diyaudio.com/community/...-corner-placement.337956/page-38#post-6486878

What were the poor results? A very small/narrow vertical coverage window? As that is what it looks like in the linked post.

There isn't much that Jack didn't simulate I'd say. 😀 Hope he chimes in.

If I recall correctly (and that is perhaps a 50% chance) you need shading to widen the vertical window. That is what you did, Wesayso, to get decent response standing to complement your excellent seated response, right?. David Smith demonstrated that long ago; check out his line array thread on this forum. As I recall, the more perfect (smooth, flat) I made the response at whatever height I was observing it, the tighter the vertical window got. This reminded me that equalization is position dependent and perhaps especially so for LAs in the vertical but I also observed sensitivity to distance
