In the case of real speakers, if the frontal beam is so large that it can engulf the whole head, then the crosstalk is 100%. As the speaker is moved to the side crosstalk will somewhat decrease (not at all in the bass) due to the attenuation going around the head. Maybe this is what you really have in mind.
Yes, that's what I always have in my mind when talking about the propagation of pressure waves through air
There is no speaker that creates a sound beam that would only "graze" your ears. The Geddes Nathans I use are considered high directivity:

Next time you are localizing something between say the center and the right speaker please turn off the left speaker and let us know if the image shifts or not.

Just did a quick test and moved the right speaker to the center and level panned a femal voice to different locations between center and left. I don't have any problems localizing phantom images between the speakers. Do you?

high directivity ?

Your left ear will still hear the right speaker, even in the middle of a field.

Yes of course. Not sure what you're arguing against or for though.

oops, I got off track, nevermind. The center image was so solid with an ambio-barrier, I never listened to a stereo setup again. I gave up on surround too. Mono, 1 speaker is all I use now.

yes. see my picture to the left. Sometimes (especially on older rock) I'm missing guitar (or voice, ouch).

I often change setups (weekly).
And I'm usually a project or 3 in construction (or waiting for parts).

Thanks for commenting on you experiences with ambio. Very appreciated. I hope more will chime in. The more details the better.

Quote:
- Ambio isn't perceived the same way by everybody
- 99% of all recordings are "incompatible"
- Having two speakers in front of your TV is "impractical"
- Putting a panel in front of your face is even more impractical
- People don't like solutions that put your head in a vise
- People don't care about realism (99,9% of all great paintings aren't photorealistic)
#1 probably accounts for the lack of consensus. There is more subjectivity to the listening experience than we are aware of.
#2 I donīt quite agree on this one.
#4 Since the arrival of software solutions only necessary for the high frequencies. That, at least, is my experience, supported by no one else so far.
#3,5 and 6. For some or most people, I suppose you are right.

Did anybody else try this? I'm wondering if people perceive phantom sources between L-C (or R-C) and L-R differently?
