I haven’t read the entire thread, so this might have already been mentioned.
But if one cares at all about imaging and soundstage, then pa speakers should be avoided.
I have heard dozens of pa speakers at many different price points in home systems, driven by good quality amps, and have never heard a wide, deep soundstage, with good layering, nor precise placement of musicians within it.
They all tend to project the music out into the listening space, and reproduce it in a very flat (not talking about frequency response).
