I don't care about off brand diaphragms. Someday I may, but as of now I've no experience with them. I just dislike faulty logic. Tell me something is no good, but don't use an example to prove it that doesn't prove it. As for double negatives if I took the negatives out (possible to prove true) the meaning would be changed. I could have said impossible to prove false, but is that any more correct?Originally Posted by boputnam
Neither does most everyone here.
I gotta wonder then, why did you post, at-all...? Some altruistic pursuit of benevolence toward non-JBL diaphragms? That, and the double-negatives ("I believe this is impossible to prove untrue...") are tedious to this reader.
It's interesting that their are persons on this thread who are sticking up for other diaphragms (I have no idea if they are right or wrong) and it's me that seems to be being piled on (unless I'm paranoid ) and all I've done is asked for more than "because I said so". and for the reason that this discussion has dug up so much emotion.
As far as JBL having a philosophy of only using genuine JBL parts. You would be hard pressed to find a manufacturer that doesn't have a simular philosiphy. I imagine they have a philosophy against using other peoples drivers and horns and any thing else they make. Wouldn't you? I'm not knocking this I'm just saying that by itself is hardly proof that theirs are better. There may be proof but that isn't it.
as for my spelling, I thought we figured out I couldn't spell a while back. I'd use word and then paste but I quit being able to paste from word a while back and if there is a spellcheck to this I'm unaware of it.
This is really quite simple. Those who want genuine JBL diaphragms to continue to be available are obliged to discourage the use of alternatives, as that practice will hasten the eventuality of their no longer being so....

Thanks I'll see how it works. I imagine that JBL's motive to continue to service discontinued drivers is the same as any manufacturer with a large installed customer base. If hundreds or perhaps more of pro sound companys all of a sudden had to start replacing JBL drivers because they were no longer serviceable, JBL would probably be way down on their list of prospective venders. The thing to probably watch for is when some companys are trying to get a product out of the field and they don't dare quit servicing it they start making it more and more expensive to keep it running. Hopefully that won't happen.
Next time I see faulty logic being used to prove something, I may very well post again. I'm not saying I never do it but never knowingly.
It would be fun to run a Poll on whether the Hoards of Lansing thought Lord Zilchvonucurvea could tell, hear or measure the difference if aftermarket diaphragms were secretly swapped on his beloved diy specials by DRG on Xmas Eve.
Heh.
Zilch has asked Santa to Aquaplas ALL of his diaphragms already....
Just what is this and what are it's propertiesHeh.

Try using Search.
While that is an excellent point, it never entered into my thinking...
I always give advice and make recommendations based on my personal goal of attempting to achieve the highest performance possible for a given driver, design, system or what have you... I do regularly run into a situation where the recipient of the advice would prefer the quickest, easiest or least expensive way to get respectable performance... I almost never think in these terms unless I am specifically asked. I am not trying to be a snob about it... I was just brought up with the notion that it is better to have less, but have the best quality you can afford instead of a lot of stuff that is second rate. Unfortunately here in America it seems we are going further and further away from that... some call it the Walmartization of America.

Bed time you guys.
Where did anyone use faulty logic?I think you're being "piled" on because you're driving the dialogue.You aren't taking into account system design. JBL has a propensity for developing complete systems. Read the attached Everest II White Paper for an example of total system design. Feel free to replace the diaphragm in the 476Be with whatever aftermarket diaphragm you wish.There is a post somewhere by Don about installing a Spell Checker. I find it's easier to simply type the whole mess up in Word and then cut and paste.
When? Send them to me and I'll do them for you.Heh.

During a recent conversation with JBL it was decided that alot of these guys wouldn't be able to hear the difference.
You've been reading my posts over the years haven't you...
Possibly. Hence my original statement:People should feel free to post their graphs of PWT measurements as well as subjective analysis for a variety of solutions.
