I couldn't figure out how to get more than one picture to upload so I put several in a word document - hope that works You talked about organic materials as possibly improving sound - how about organic shapes?Since a significant part of the function is to randomize then it seems that geometrically exact shapes may not be the best answer.The first pictures are circular sections used with drywall but wouldn't more random shapes provide a more randomizing effect?Maybe a purple spiral sticking out of your wall too radical in terms of looks but what if say instead of a semi-circular pillar of constant cross section - you had a conic section, moving from 2' diameter at floor level to 6" at ceiling height, or what if the cross section is not circular but parabolic, or hyperbolic or just a random squiggle?

Fulcrum, yes, something like this. I do not exactly understand the purpose and a needs of the rest pictures but the first picture is something close to what I am considering to do.  The problem with your “organ” profile is that it is consistent but I will be looking at more inconsistent or random reflection pattern. So, the individual “pipes” would be different decameter and even different heights. BTW, I spoke about your options with my carpenter and he told that he has no problems to make curved walls – he did it past. He does it by submerging special type of drywall into water, bend it and then let it to solidify it this way. I see a problem in ether his or your approach although your walls might have winning reflective profile but they are “hard” walls that would not play acoustically so well. if you find a way to make your walls from some kind of acoustically-active surface then I think your wall would be more effective. If you look at the material the some companies do the ceiling acoustic clouds then it might give you some idea.

I do not say that you need to imitate them but the glossy, piano-finish surfaces might be something that shape your professional pride but the very last things that we are looking in acoustic treatment or our listening rooms.

before doing anything I say you can use a spray made for making dried plant steady and stop them from exploding their body in air.(no idea what was the name of that spary) it can much help and make your tubes safe in your room.

Might be this is a good idea if the spay would not seal the fiberglass texture and would not make it less acoustically absorbing. Do you know a name of such a spas for me to try, I truly do not know what to look for?

And what you mean saying:  the tubes will dramatically randomize MF? I dont wanna play technical fellow here but I can see that the tubes in your room are already dramatically absorbing all your MF + HF and you like it and of course they can randomly scatter some MF but its like 10-20% of the sound to be scattered ... saying MF means from 150 hz to 1khz to me

I do not think that the tubes are dramatically absorbing all your MF + HF. I think that they do reflect something and whatever reflection the do they, considering that they will be different sixe tubes, then they will reflect randomly for any driven point of location. It is hard to me to estimate what frequency we are talking about. I do not write a book about out acoustic reflection but am trying to make my room to sound right. I have a wide “endless” opening on the right and left from my listening spot. Relocating the listening spot in front of the opening and pointing the speakers to this position I can get a feeling how my room sound without harmonic reflections, in fact I know how it shall sound. Putting back the listening spot and having the middle column I do pick the harmonic reflections. The word “harmonic” is the key as the reflections has some dominance in one region and do not have in other. The objective is to make any reflections, if they take place to be random my non-specific.
