Coherency relates to the notion of hearing a single speaker rather than a chorus of separate drivers. I am especially sensitive to this characteristic. What measures this?
Correlation and causation are not always the same. One may assign correlation when in fact there may be other factors at work.
Tell us about image height measurements. Tell us about soundstage depth measurements.
Stereo Sound Processor manufacturers? That is hilarious. Have you ever heard one that sounded real? I'm not referring to phase gimmickry that may sound cool for a short time until you realize there is nothing natural sounding about the result. Let's return to quantifying how speakers may or may not reproduce certain characteristics of music.
Are you going to echo the same "I can't tell you what they are - but I just know they exist" line?

Well, I showed you somethings which can affect the stereo image, including forward or back presentation. One problem of the way you ask about this is that if you are measuring the performance of equipment, we are not measuring you perception of soundstage width, depth, and height. A stereo image is an illusion, and audio measurements do not directly measure your subjective experience.
I have not covered image height. There is absolutely no reason why I should explain what measured factors are relevant to stereo image, as it is not my field. Obviously, someone must know how to produce an illusory sound source extending above the speakers. I have a Chesky Test CD which using electronically generated signals can do exactly that with quality speakers placed in an environment without too many near reflections.

Sorry, I'm not recalling that. So, exactly what measurements quantify what we hear as depth and width?

This is what I'm saying. I couldn't have said it any better. There's a huge gap between measurements and the entirety of what we perceive.

I have a Chesky Test CD...
Chesky does some nice stuff, but why limit the evaluation to a *test* disk? I evaluate image height with every recording. Especially those like the ASO Firebird where I participated in the recording - and heard takes from the master tape during the three day session.
You're not alone. No one covers image height with *measurements*.
"This is what I'm saying. I couldn't have said it any better. There's a huge gap between measurements and the entirety of what we perceive."
Actually, you don't get the point. I don't know how it be made clearer, but you manage to muck it up. When we measure the speaker, we are measuring the speaker, not you. You are subject to all sorts of internal influences which have nothing to do with the speakers.
"I evaluate image height with every recording. Especially those like the ASO Firebird where I participated in the recording - and heard takes from the master tape during the three day session."
I would rather enjoy the music or other program material on the recordings.

Choose whatever graphs and numbers you please. And, correlate the results.
Do enlighten all us!
... either sudden change of subject, or just dead silence.
Actually, you can see both right now - from both (non)respondents.
All those characteristics are brought into complete clarity and quantifiable means via:
Horizontal axis avg thru 40deg and step response
Not.
Horizontal axis avg thru 40deg and step response , if you could get rid of the frame buzz and stored energy you so enjoy.....
