Please see my posts, above about what I call the 'thump' test.
A woofer so thumped with ring when not connected to anything and will self damp when bridged with say.....a paper clip or short piece of wire. The amount of amp damping available is related to the RDON, (Resistance of Device ON) and with additional relations to the feedback loop, if used. Lower RDON results in a higher DF.
With a maggie, the mechanical damping of the mylar may, at low levels, 'overpower' any electrical power generated. I don't have a clear idea about how much energy these panels store but at higher levels, it may become a substantial part of the total energy storage.
Your 'magic' driver material kind of reminds me of the Original Ohm/Walsh driver which was a down facing cone. It DID NOT respond as a pistonic cone, but rather the waves generated by the VC movement traveled down and excited the air in so doing. Omni directional, too!
Now, as to one driver exciting another thru a crossover? The crossover will still deal with the signal based on frequency. So, a distorting woofer kicking out a 6khz howl will destroy a tweeter.
I'll go ahead and visit the schematics page and see if I can make sense of it.
Too much is never enough
