I wonder, if to embrace the idea that I described in the Maturation Shields article (a few posts above) then how those external horns might be constricted?

They need to be solid and not to be afraid of sun/rain/snow. They need to be acoustically tough.  Still they I do not think need to be brick-made-level fundamental masonry construction and need to be relatively easy removable if I would like to.  Not to mention that I would like do not hire 30 people to built them and convert it into a “federal” projects.

What I think is following, and places advice me of you have an experience with it or some ideas.

1) Calculate the horn geometry, parabolic profile and if necessary curves using the windows size as mouth
2) Remove the windows
3) Attach to windows whole 4-8 metal bars of 12-14 feet that are custom-made in accordance to the horn internal profiles
4) Wrap wire around the bars, sweating a inner-skeleton of the horn
5) Continue wrapping wire around the bars, interlaying it with sheets of paper/cardboard
6) Pure (poor, purr -how the hell to spell it!) cement or concrete over the wire/cardboard, making the horn.
7) Repeat the cement application for a few times until will be as I would like it to be.

I see it a relatively simple and cheap project, a weekend or two long. Do I know what I am talking about or I just BS myself?
