It's not that they can only "handle" so much power, it's the demands you place on the speaker to achieve the volume levels you want.
Speakers draw power from the amp, so as long as you don't try and "draw" too much to achieve a volume level that is beyond the speakers (drivers in that speaker) capabilities, you can never actually have too much power in standby, where the "too much power" & "specs of a speaker" come into the equation is having more available power than is recommended, and trying to actually push the speaker beyond its limits, then it simply becomes a matter of personal self control.
As far as the minimum requirements, this is too help limit distortion from trying to force a speaker to go beyond the limits of the available power, amp clipping can destroy a speaker just as much as trying to get it to play beyond its means, and quite often it does.
The so called "sweet spot" I mentioned earlier has to do with having enough power for the driver(s) to move as effortlessly as possible without taxing the amp, but to also have enough headroom that this effortless motion also continues throughout the speakers entire range, not just at the "normal" operating parameters, just because a speaker can play and even seems to play well, doesn't absolutely mean it's playing at its most efficient. And until you actually experience a speaker doing this, many times you won't even realise it.
For example, I've been through many amp changes, started with just my pioneer receiver driving all the speakers in my system, and it would still get to reference volume in my room. But until I actually bumped up and had more available power, I had no idea of what I was missing and was able to experience a truly distortion free sound and the phenomenon of volume turning into sound imaging, and not just seeming "louder", which quite often is actually mild distortion.
