With that amount of wattage, you would only be listening to the tweeter, as the bass driver would not have enough wattage to hardly move, if move at all.
That statement right there shows that you and your associate have a fundamental misunderstanding of how speakers use power. When speakers are tested for efficiency, the most common method is to feed them 1 Watt of power and to measure the resulting decibel level 1 meter away. The M80s measure at 91dB in an anechoic chamber and 95 dB in a typical room. The tweeter alone is not responsible for those levels.

In response to RickSean's last post, I've confirmed that the M80s have no problem producing respectable SPLs with a quarter watt and less right down to 40Hz. See the chart below. The background to the measurements for power is shown here. RickSean, the arguments therefore that you have posited are null and void. I also want to point out that capacitors don't require any "powering up" as they are passive components. And from what I've witnessed out of my low-cost receiver, Denon is to be commended for their engineering prowess. So, we are now back to square one.

The extent to which you're geeking out about this is something to behold. I love it.

I of course geek out to keep you amused . So here is some more amusement for you. I have no idea what the minimum power rating for a speaker means. At first I thought it was to ensure adequate dispersion. But my ears told me that couldn't be it and then I checked the off-axis frequency response graphs for the M80 and they were excellent with 1 Watt. If anyone knows, please tell us. With regard to cone control and precision of movement, I am curious how RickSean confirmed that a higher power amp provides an improvement in this area.

As long as I've been researching speakers, most manufacturers websites give a recommended min/max amp rating. I think it is just a recommendation and you might be reading to much into it. Look at the 80's, they say 400w for max power. We all know they can handle amplification that far exceeds 400w. As I've mentioned before, in recent lab tests Axiom when testing the new amp drove a pair of m80's continuous for 2 weeks 24hr/day with 700 watts with peaks exceeding 1100 watts.

Max power I can understand. But why a minimum that is clearly far greater than the minimum that I and others experience. A half watt is a far cry from 10 watts.

Mo, as Randy indicated, those suggestions for amp power aren't very meaningful. I suppose that it could be said that the minimum suggestion is something that the speaker manufacturer believes would be adequate to power his speaker even on peaks in "typical"(whatever that means)situations.

What you're suggesting makes the most sense...sort of. If you're listening to your M80s at an 1/8 watt average, 10W is more than plenty for most material.
