I've totally lost the plot....
I got them in my L40's, but here's the problem
The right tweeter developed a buzz. So I found another one, and it had the same buzz.
Then I swapped the left one for the right one. Same buzz.
Then checked all three using the left box. No buzz. WTF?
So I guess I'll have to pull the x-o out, but I can't imagine wot in an x-o would cause the sound of fractured diaphragm, which as lot of you would know, is very distinctly different to a electronic component malfunction.
Got me beat.
:oops:

I have a crossover buzz that sounds like a diaphram gone bad... I now have a perfectly good set of DCM-50's and new diaphrams in the 4592's...

Stuck in the 70's
Recently I had a speaker problem that I went round and round with. Sounded terrible, and it turned out to be a fatigued solder joint on the cone wiring that runs from the voice coil to the speaker's driver terminals. The joint looked fine, but a light tug on the wire and it pulled clean out of the terminal strip! It left a perfectly shaped hole in the solder behind.
Solder connections on loudspeakers (and spade connectors too) have caused me lots of grief over the years. Maybe you should retouch the solder joints on your crossover boards, Lee. 130 dB puts a lot of stress on them!
As the speaker operates it will cause a high frequency disconnection that can manifest itself in many different ways.

130db puts stress on everything. At Tim's the other day there were spiders looking for a way out of the house, we had, briefly, considered acoustic pest control as a viable business opportunity , not to mention being just plain fun....
