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,

So I built my system on research by Prof. Edgar Choueiri made during his work at Princeton in his 3D Sound Lab I experienced over 20 years ago: 

The moment for me was playing on humble Sansui speakers in my home under construction listening to a recording processed through the BACCH filters, my mind was officially blown. 
BACCH 3D sound works best with very directional speakers that limit reflections. I have optimized my room from the listening position on my current system with time alignment, phase, and room interaction on 12 biquad filters operating at 96/24 on each of my 8 channels of my fully active set up. 
The image is stable and amazing on my system and it feels like being there, friends and neighbor’s jaws drop, but it actually gets better, and I’ve heard it. . . the last piece is BACCH. Take a look at the technology:

Hoping to add it this Spring!
