Achieving a speakers max potential


Can someone help me better understand the relationship between the amount of watts driving a loudspeaker and reaching that speakers maximum potential? If for example a speaker's power handling range is 25 to 150 watts, will you not reach the speaker's full capability if it's not seeing 150 watts behind it? Will you hear more detail and information out of that speaker if it's being driven at 140 to 150 watts than if it was being driving at say 60 watts at the same volume (dB) assuming of course the amp or receiver and speaker wire are of high end audio quality? I tried to find a thread on this but nothing turned up. Thanks much.

you wont reach its potential with alot more then 150 watts, you need headroom for an amp to be comfortable driving a speaker, far more speakers get blown from lean power vs too much power.
Assuming the power is clean and of high quality and the concern for blowing the speaker is not there, what I'm asking about is the speaker's potential performance. You know how when you go and audition speakers, the salesman will always try to use the most powerful highest quality and most expensive amp or receiver so you will hear the best out of that speaker. What I'm asking is if you can afford to purchase a higher power amp of high quality vs a lower power of high quality, will the speaker perform at its best performance simply from the higher wattage? Will the drivers produce the best sound they can simply from more wattage than from less provided you stay within its spec? Does that make any sense? Hypothetical situation: You have two Rotel amps or A-V receivers side by side, both high quality well built units. One puts out 75 watts/channel into 8 ohms and the other 100 watts all channels driven. You have the volunme set so that the speakers are producing say 85 db in the room. The speakers' power handling range is 50 to 150 watts at 8 ohms. Will more detail, resolution, bass ext, and soundstage be produced by the 100 watt receiver over the 75 watt? That's what I'm asking. Thanks.
There are so many variables in your question that it is hard to answer. A speaker reaches its potential more by the elimination of poor components/conditions, as opposed to the introduction of more power. Most speakers would reach their sonic potential with a 50w quality tube amp/ic's more often than with a 250w Rat Shack pa amp w/home depot ic/s. Not to mention that one persons maximum potential sounds like fingernails on a chalkboard to another.
