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

sometimes these discussions leave me speechless

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

I’ve always had power amps that far exceeded the power handling capacity of my speakers. Never damaged a speakers. Particularly with solid state amps most speakers benefit from having large excess capacity, yielding more solidity.

As my systems got better the volume of maximum enjoyment went down, until now 65db to 75db is typical… cracking 80 if I am enjoying it really loud..

....nothing like the fragrance of fused voice coils to flip enthusiasm into ennui...

Note that any tube guitar amp from a 5 watt studio amp to a 100 watt whatever will often be used overdriven with distortion into the speakers for DECADES with no harm done. If people are lame enough to drive their delicate little home stereo speakers to the edge with a high powered amp (especially a solid state one) there's little to be done for them.
