BTW...
I think I've also figured out why there is a ~$50 price difference in the diaphragm you get from EV and the one you get from Klipsch...
From a conversation that I had with Trey Cannon, I realized that what Klipsch sells you is the ENTIRE diaphragm assembly. Not just the diaphragm itself. The diaphragm assembly is the round black part, into which fits the diaphragm itself. If you replace it the Klipsch way, you don't have to solder in the diaphragm, you just have to knock the horn off the old diaphragm assembly, put the 3 parts back together, then solder the wires on to the new assembly. (with a few gaskets and screens thrown in for good measure...)
The thing to remember (if you buy just the diaphragm) is to make sure you have the red line on the replacement diaphragm (which indicates the location of the "return wire") to line up with the "gap notch". On both of my tweeters, the diaphragm lead which was connected to the "return wire" was soldered to the black post. (as opposed to the red post.)
Does this line up with everyone else's experience?
Thanks again to Trey for the helpful information and the pdf files he sent me.
