I've found them generally reliable. Was there anything in particular you've found
not to be trustworthy ?

Well, I have a pair of monitors that have a warning on the back not to
operate them with an amplifier less than 250W. They sound great on my
60W Citation II amplifier, and have for fifteen years now. On the other
hand, I can name a bunch of speakers that are rated for comparatively
low power levels, that can benefit from a higher power amplifier because
of the low output impedance.

Where does the "100W" rating on the speaker come from? Is it related to
the minimum allowable power rating to get a certain sound level? Is it
related to the maximum continuous power level the speaker can drive without
the voice coil overheating? No, it is made up by someone in the marketing
department who thinks that's about the right power level for the box.

The power ratings on speakers are not measurements.
