Post Subject: Thank you Romy very well put.Posted by morespeakers2 on: 2/4/2013

I would like to thank you for taking the time to give me a very satisfying answer and explain in detail your views on the whole subject and give a little more insight in to how you do things.

Yes I suppose I really knew all along it was coming and was trying to avoid it. The fact that I just need to get some S2's and see what they do for myself. I thought I could possibly cheat a bit and just apply what was done on the S2 to the readily available 288 frames.

I need to work on reducing the thickness of my skull as the fact of "No substitute for real life experience" was just very recently driven home for me with helping my son with his first pinewood derby car. We went on line looked up "almost" everything needed to win but lost to a kid with more experience. We had best profile, best weight distribution for the very track we were running on, super polished axles that spun for 30 seconds, actually longer than the wining car and many other well tested tricks but the one thing we missed that was not done to our car was having near perfectly balanced wheels. So in real life at speed that very small out of balance of our wheels caused the car to loose and loose by only a few hundredths of a second at that as the winner demonstrated to me. This very lesson is what you are so kindly trying to tell me with the S2/288 and I get it.

You mention even you were not crazy enough to do your own drivers and that I couldn't be this nuts.......well we shall see, I am pretty nutty and growing up watching my nutty dad make nonexistent very intricate parts for his early brass automobiles has given me quite a bit of confidence in this area.

As to making new diaphragms in the future , I thought it would be relevant to link this video showing an AEA ribbon mic being manufactured as an inspirational demonstration. Making a compression driver obviously has much different tooling requirements but the press at 1:26 shows the basic idea for molding a driver diaphragm, press for a diaphragm need not be as substantial as the one for the mic screen. I do have all the tooling right now to cut a few different wood phase plugs to replace the plastic Altec tangerine plugs on the 4 way all wood horn non digital pa system I am working on at the moment. This is a real project going on right now for me but should yield some findings that will be applicable to S2 project later on.

Again Romy, thanks so much for the great answers, I will keep you posted on my progress.
