I wonder how Barleywater's Pluto clone satisfies the requirement of "a speaker with radiating wavefronts that project back to point"?
Markus this is the internet, not a refereed journal. You could have looked up the papers in the same time it took you to post the request that I do it for you. If I had them on hand I would have posted them, but at that moment it was not convenient. Yes, I think that those are the three papers.
Exactly, a hypothesis, not a fact. Even if his hypothesis turns out to be of value (and I believe it is), it doesn't allow for the conclusion that spurious cues from other frequency ranges aren't detrimental.
Furthermore he is talking about natural sound sources/fields. Our topic is 2-speaker stereo in acoustically small rooms.
By the way, his papers make a good case for crosstalk cancellation and the perceptions that were reported here.
More than a little annoying, no? 😉
Earl most certainly should have provided a specific reference to his specific claim.
What I like about Griesingers work is that he actually looks at speech and music and not clicks and pink noise.
My woofers are crossed at 500 Hz. If I listen to the woofers only, there are directional clues for sure. But they are weak and they are very diffuse. When I listen only to everything above 500 Hz, the directional clues are overwhelmingly more powerful and precise. Adding the woofers afterwards has NEVER changed the direction of any musical signal for me.
I really wonder if anyone can report the contrary. 🙄

Play a slow sine sweep - the image stays in the middle at all times? Lucky you...
ScottG is listening to a baritone without harmonics. 😱 You are listening to slow sine sweeps 🙄 ... anybody around here listening to real music? 😕
Rudolf
Just test tone and log chirps, why would you need to listen to that damned music, it just covers up the sine waves anyway.........
..and isolated test to prove an isolated point.
Sure, I'm listening to music right now. 😉
Something more "real-world" then?
Is your 500 Hz (and below) system dipole (with a decent null at 90 degrees)?
Choose your poison.
In-room measurement - which shows that below 300 Hz modes are ruling everything.

At two meters? At one meter? At half a meter? At a quarter of a meter?
In any event, there does appear to be quite a lot of pressure loss just below 500 Hz off-axis.
Have you tried rotating the <500 Hz portion with the most extreme condition of pressure loss nearly facing your position (with music)? (..say, 80 degrees - outward or left of left speaker, right of right speaker?) And from there eq.ing it flat from your position?

Yes, it's what I would expect (and have also experimented with), depending on the material. (..and I would include most material.)
He is however asking for something to the contrary - and I've also experienced this. But the conditions to do so are not what I would call "normal" (in the context of stereo).
Hmm, is that what I "want to hear"? That presumes I wanted to hear a particular result - which would be incorrect (at least for me).
