Never said I wasn't, however I believe it to be irrelevant because everything starts as a dream.
"Please dont be offended"
The easiest way to avoid being offended is to not be insulted.
#1 "but your posts suggest you understand all the issues
#2"(which you don't)"
#3"but want someone else to do all the work."
#4 "You will need to do all your own R & D"
Problem with statements
#1. I never claimed or Even suggested that I understood all of the issues, if I understood all of the issues I would not post probable questions. I believe that your statement is unfair and unnecessary.
#2. "(Which you don't)" IMO offensive and redundant, I do not come to Lansing heritage and participate in open forms to be told what I do and do not know, I would rather discover it through open discussion.
#3. There is no evidence that I desire anyone "to do all of the work" and moreover it is not the behavior I have ever demonstrated here.
As a matter of fact I contribute in what ways I can, monetarily. I do not give advice, if I believe others can answer the questions more adequately, which is in most cases.
I have not asked anyone to sacrifice anything of their own, nor do I feel any entitlement to any services that are not freely volunteered.
All I ask is for an open and fair forum to discuss my ideas, which sometimes are very dream like.
#4 it is apparent that I will be doing all of my own R&D.
"If you care to do a search on google"
This is over the top! I read at least two hours a day about speakers including hundreds if not thousands of posts here on LH.
It has gotten to the point where I often run over the same posts while doing searches for completely different things realizing that I'm often rereading subject matter, that is saying something considering the size of the library here.
"and understand the engineering of a compression driver it will be come clear that it needs acoustic impediance loading , particularly at resonance and below. You will also need to work out what to do about a rear chamber?"
You are asking me my own question?
I think I made it clear in my first post, which I reread just to make sure, I am aware that the diaphragm needs to be loaded. I have already experienced similar problems with my composite T030 drivers, which I solved.
"Hence the Waveguide and all the necessary tailored Eq for a flat on axis response."
I believe you may be over complicating the issues, my reference to a waveguide was an inaccurate statement, I would like a radius transition from the aluminum ring around the diaphragm to the baffle board. However lots of drivers successfully operate without waveguides that have a similar configuration, remember it is already a speaker. My job would be to fool it into thinking it was on a horn.
"The Waveguide also assists control of very early reflections, without which the exercide would be a"
"waste of a good driver."
Please explain to me the waste part, if the driver does not function as I intended to or expected it to then I can, within a few moments, converted it back to a compression driver. no harm done, no money lost. Only some time, which is all we really have any way.
"You are better of buying a the right horn(s) and doing from R & D. If you dont have Clio and all the necessary software tools the odds are it will be crap shoot anyway."
