Yesterday I lowered the crossover on my Creative Sound ribbons, and the ribbon ceased to work after about two hours. (The CSS riboon appears to be an Aurum Cantus G2si for all intents and purposes.) I've blown a ribbon before, and the ribbon actually blew to bits. (I was measuring the frequency response and I forgot that you can't do that to a ribbon without a filter in line.)
Anyways, the ribbon is intact, but no sound is produced by the device.
Is the ribbon blown, or the transformer itself?
The driver has a thermal limit of 30 watts, and I was powering it with about 20.
Before the driver failed, there was audible distortion.
Has anyone here blown a ribbon? And if so, is there a way to diagnose it? I'm reluctant to purchase a replacement diaphragm if the transformer is history.

When a ribbon blows, the aluminum diaphragm will open like a fuse. If the element is intact and you get no sound, the trafo (or connections to it) is the only other thing that could be bad. But I have no idea how you could do that and not damage the element. Low frequency might do it, but the last time I did that with a Raven by mistake it just stretched the element to heck. $10 for a new element, and half an hour of painstaking work installing it and it was back tweeting. I've overdriven them and stretched (but never melted) the elements several times, but never hurt the trafo. In those cases there was no discernible distortion until the ribbon smacked up against the screen. That was quite audible.
ugh that's a bummer
the element looks alright, a bit stretched out, but intact
but when I connect the speaker leads, there is very faint amount of sound coming from the element, and it ends almost as soon as I touch the leads. (which is odd.)
So it plays faintly for a split second, then stops.
