Congratulations on the construction and installation of your horns. May your pleasure at the results reward your effort and expense. I find their installed appearance even more geometrically striking than anticipated and I suspect now that some of the design choices I wondered about earlier can be attributed to a conscious or instinctive design eye.
  
Actually the horns look and feel absolutely the way how I envisioned them. There are decorative things that I do not like, where my carpenter override me and I let it to pass but they are minor and I might live with them, at least for now. There are some mistakes that I recognize now, purely my decisions but they still are something that I would characterize as minor.

In addition to vibration, remember the house framing is going to settle under the weight of the horns and the horns themselves will bend and warp a little as they respond to their own weight and the temperature and humidity in the attic – (they are not waterproofed on the exterior). This settling is going to expand the gaps over time and you may want to anticipate this.

Good point and I have brought it to my carpenter attention a few days back. I think it will be between him and drywall specialist that he desired to ring to the project.

About the rest, interpreting what was advised to me in the site, in the personal emails and talking with my local people we decided to indent the horn ¼-½ inch behind the drywall and let the drywall specialist to finish a perfect shape of mouth window make from drywall, terminated with plastic/meal corner trim. Then we will run some kind of door/window trim with some kind of elastic material between the very edge of the drywall and the horn.
The concept is clean and it will work but I do not like the idea that the drywall edge will be perpendicular. I would like the edge of the drywall if not continue the curve of the horn but at least to be at angle and to have slope. I need to sell to this idea my carpenter. I wonder if exist any drywall anglular terminators (corner trim)….
