Romy, very interesting stuff.That was exactly the kind of info I was seeking with my post on curved corners below that your readers took such exception to.Granted I had the idea ass backwards as a great number of people who contacted me privately pointed out.A couple of the people who did contact me asked to produce 1/4 tubes to fill in corners, partial tubes to diffuse sound from side walls and curved panels that can be wall mounted with tilt and swivel brackets to allow them to be adjusted for the best sound.

Fulcrum, I did see that you have thread but I hardly understood what you are trying to do or to say. Your illustrations are very inadequate and your idea about the application of curvature walls is NOT very clearly expressed. If you are a maker of curved walls and trying to soloist some business at this site then it is fine. I never had any attitude ageist proprietors fishing for clients but I always demand it to be in context of the advancement of sound reproduction techniques. I did not see a lot of it in your posts and I did not pay any attention to them.

To my knowledge the addressing of wide size reflections is not something that people too worry or care.  If you have a large wall behind let say 10 feet back then the mass reflection from the wall create a permanent contra-pressure and people do not acknowledge it and it is virtually imposable to tune ourselves off from it. The reason why I was able to catch it, besides my extraordinary anal retentiveness, is become in my case reflective panel is very distinct and located in something that I would describe as “reflective vacuum”. So, if you wish to advance what you do from a perspective that it be interesting for the people like me then you need to come up with a set of measurements of front vs. back pressure or with an elegantly expressed speculation that curved surface address the back-pressure subject and how to learn the benefit of it.

Generally if you were in my disposal next town over then I would heir you to make the wall under the midbass horn completely wavy – 10-15 horizontal crooked waves under the edge of the horn - in the Salvador Dali style.. However, if you make any acoustic claims then you need to do it not from sheetrock but from acoustically effective material, the compress fiberglass appears fine to me. Anyhow, you need to work on the presentation of your idea and to compile it into a complete product and deliverable package.  The way how you present it in your thread did not attract my attention. I would expect the people like you were able to foresee the reflective pressure of non-curved walls and depends of the reflector size and distance of reflection to find out what frequencies are in play and what rate of wave absorption material would make sense to use for the given reflective situation.
