I did build a slightly bigger THAM12, som 4 inches higher and deeper and 2 inches wider. Also changed the first part of the horn, which now start at 1,8 cm at the front. I will post a drawing when it's finished. Also a larger mouth. First tests were very impressive, much more and deeper low freq. Also less boomy than the THAM12.
If I may, I would sugest the latter, simply due to the fact that you may find new solutions or answers that benefits alot of other potential builders on the way, it is allways beneficial to break new ground, given that you feel you have the time and resources to do so.
I have to question myself, keep it small and "simpel to build = euro's" or go alle the way.
An excellent quote, this also says a bit about my ramblings above, in that some one else might know and could tell you about it
the more you know, the better I understand I don't know nearly enough...
I'll be more then happy to try, just remeber that I'm not the one with all the answers, far from it, and just like you I expect a healty correction if needed.
Could you help me in trying to find how to shape the throat? Feel free to correct or even tell me I way off...
My guess would be that he adresses the initial energytransfer to the hornpath and setting the propper driver friendly environment, kind of what we talked about earlier.
I did read some comments from Tom Danley, that the S1 - S2 is key to proper loading, but what does that mean.
1 - WHAT IS the most efficient Throat for the THAM12. I guess it will always be somewhat asymmetrical because the first segment is not q square box by itself. I favor the V-shape (just feeling..)
I belive there is, but it is not yet clear to me exactly how to do it, or perhaps this level of detailed simulation calls for akabak scripting wich is an engineers wet dream, but not this perticular engineer as I found it to be very complicated to say the least, sorry, but perhaps someone else could shine a light on this for both of us.
2 - is it possible to use HORNRESP to figure this out. I see some parameters that handle this subject, but have never seen anyone using it.
