3D imaging

I I started thinking about this yesterday. What makes speakers produce a 3D image? I figured the first thing is the recording itself. I'm guessing mic placement has a lot to do with this. Next I would imagine is room,and speaker placement. Downstream gear certainly has to have some effect on this. Does the crossover have something to do with providing this "illusion " for lack of a better term? 
     Now please understand,I don't have anywhere near the technical knowledge a lot of you folks have,so as you explain this phenomenon,please dumb it down for me! 
    Thanks in advance,

I've had the Chartwells for a couple of months now. I started placement farther out and toed in. About the same place that I have the Nola's set up. Sounded good,but the 3D imaging wasn't what I was looking for. I then started moving them a little closer,and bingo,we're getting there. Eliminated toe in,Shazam! Spooky 3D imaging! Today,I moved them about 6" closer,and my heart is going pitter patter. They say football is a game of inches,add the audio game to that.

Stereo is an illusion for sure and  audio is certainly not only science but also physchoacoustics, brain/ear are as yet inseparable... well for most...

there is that pesky brain/ear/ego bit as well

Many of us think high TIM amps don’t image well, 

for more insight on your LS 3/5a and why they are so good, check out all the work the BBC went to in creating them, lots of science in that one and some ear brain also

while not strictly an 3/5a, I have a set of modified KEF101 that are image champs...

how fun enjoy your music

also get Jim Smiths book on getting better sound

IF you want to experiment with a very affordable low TIM SS amp with gorgeous sound, try an Audionics CC2, circa 1978...

there are others, if the science of that interests you check out Dr Matti Otola papers on subject

I have read a bunch of articles online about the LS3/5's/5a's. Very fascinating stuff!  I feel like I am listening to an important part of audio history. I am definitely experiencing pride of ownership with the Graham Chartwells.
