"Electrical damping is almost always an order of magnitude greater than mechanical damping"

Sorry I don't understand the expression (English ain't my first language)

"The difference is that in the pistonic range, the forces required to bend the diaphragm are small enough that it operates as a rigid piston. "
Is that because higher frequencies are smaller to "fit" into the diaphragm and push it into the non pistonic range? (smaller driver = higher frequency of cone breakup)

"usually if the cone is made stiffer, it tends to breakup later but harder."
I assume you meen "higher in frequency?"

So, as I gather from what you are saying, the damping of the system loses control over the cone's independant motions, and one can not tell from thiele/small parameters the properties of the non pistonic range at all..?

This is great info. Thank you.
