I'm not sure what type of crossver is being used, but I have a pair of Raven 2's that I have been running for about 4 years without issue. From time to time they do see ear splitting volumes for short periods. I am using a D'Appolito designed crossover at 1800 Hz.

I've never had a problem. I think that any low freq information is destructive to them. They really need to have a high order crossover to be safe. But ribbons are very cheap (were free to me for my R1) and are easy to replace.
Now the Raven 1 is a different. I am working on a design using a R1, and I don't think I would suggest using it below 3500. It starts to sound a bit thin when you ask it to do too much. Again high order crossover is in order.

Re: Raven Crossover
Perhaps the Raven design is not intended for Industrial
applications.
We used 2 poles and a DC blocking cap.
