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.
