John, I am bit puzzled with your response.

I do not know what would be a proper material for cone/dome of diaphragm. The source where “tone” is born in compression drivers is absolute mystery to me and I in my holly naiveté believe that no one else knows where tone comes from. If people would know it then they would use their knowledge but they don’t.

What actually surprised me in your reply is your accent on phasing plug. You might be right in what you say about tone and phasing plug design but it would hardly might be related to my problem in the hand (OK, I admit the hypothetical problem as now). My Midbass horns will most likely rolls off at 160-200Hz and I do not see it use any phasing plug at all. In contrarily I think it might (might) need some kind very “messy” front chamber. What I say the “messy” I meant an intentionally high order of HF reflections and cancelation in order to keep HF as much attitude as possible. I even thought to have between the throat and the driver a small anti-horn curve that would maximize the HF mess but also would introduce a soft change of compression ratio.

Are you truly seeing a phase plug in 40Hz midbass horns? I see only contra-phase plug. I have no idea how to do it for now and how it might affect anything by I certainly do not see in there a classic phase plug.
