Can a power amp have too much power, risking damage to a speaker?

Thanks! mijostyn! 
I follow some Audiogon discussions, but this is my first time to submit a query.
Impressed that there are folks out there who as OCD perfectionist regarding good audio as I! 
Based on this experience, I'll likely join some other discussions groups. It's a great community! 
 

Amplifiers can damage loudspeakers with too much sustained high power.  If you treat your loudspeaker's voice coils as if they were a fuse, they will eventually fail.  Use some common sense. 

sometimes these discussions leave me speechless

It really can. I've damaged my speakers with large power!
