Don't want a war between anyone, just thinking about another horn project at some point, and after looking at all of the many posts of the 435 and 2435 drivers, I am somewhat curious....and want some opinions....why is the response less than flat, and the extension seemingly quite less than the TAD drivers.....they both use berillium? Yes, I am aware of the cost of a 2001/2002 TAD, I used to own some years ago. But I also remember on my 2344 horns, they were 1/3 octave flat to 20K within almost 1 db!! Yeah, shoulda, coulda, wish I hadn't sold the stuff.....but looking at the response graphs, even though the JBL's are more than a bit less money, they also seem to have response peaks, etc....and not much more extension than an aluminum diaphram.....certainly not to 20K....so what's up? Do they sound THAT much better than an aluminum LE85/2420/2421, or 2431(?) aluminum, etc??? The TAD 2001's I had were night and day more transparent, over a 2420, or 2425 back in the day..micro detail and shimmer for days, if you will....and no super tweeter needed...is there a shortcut that JBL took, that TAD didn't? Thanks, Pete
