I said 4" and 6"

And I AM an ... Haven't you noticed yet? [img]tongue.gif[/img]

Not only are you an you are an with a rally wide head "it has to sound good from BOTH seats for me"

defro

you said it wont make much of a difference until you get to 12", so i'll correct myself, if you put on speaker 4" from your head and the other on foot away, 16", i think the difference would be substatial, i'm not rying to fight either i just want to make sure i understand what your saying

Ok, I tried Dukk's analogy with the computer speakers. Right now I have my speakers set as follow's:

Its actually almost exactly opposite from a left hand drive car. My right speaker is set just above head level, 5 inches to the right of the head. Total distance straight away from the head is 45 inches.
The left speaker is at the same height, but about 20 inches left of center. Total distance straight away from the speaker is about 50 inches.

Total actuall difference in pathlength is 5 inches.
From my computer seat I can hardly hear the left speaker when the balance is set to center. It is a significant difference. I have to adjust the balance almost entirley to the left to get any sort of stage from the set.

cool test now in adjusting the level you got some sort of image, but what do you think would have happened if you could have delayed as well, the pathlegnth difference is only 5", do you think time delay would make a difference. now take that same 5" and apply to a speaker that is 20' away and one that is 20'5" away, not noticable, i guess my point was that pathlegnth differences less that one foot can make a huge difference depending how far you are away to begin with

Hey Petey - did you point the speakers at you?

In a car the close speaker is usually more off axis for a little time/intensity tradeoff. Did you mimick that?

I used the example cuz I was at work and I have my speakers set up on my desk pointed at me, one about 16" away and the other 22". I get stereo sound.

After some more testing with the same setup, here is what I have found.

I took the speakers and faced them towards each other, just like a door application in a car. HOLY CRAP!!! What a difference. The imaging improved 100%! I can actually hear the left speaker and the center image has mover over about a foot.

i did the same test at home and wasnt nearly as shocked as that was how i tested originally, so i went to my car where the front left door speaker is 46" from my head, front right 58", esentially 1 foot, adjusted time delay from .9ms to zero, result, no decent image and no center, what stage there was went to steering wheel height

I would expect that out of door mounted speakers. [img]graemlins/dunno.gif[/img]

And does that 0.9ms help out the passenger? Or does it more likely make it even worse for them? Some people care, others don't. Personally, I do.
