RE: I am convinced that is what is already happenning.

** The speakers I own are nearly 8 feet tall and have a sensitivity of 87db/watt. As a line source in a relatively small room there is maybe 3 or 4db drop from the speaker to the listener 3.5 meters away. Given these parameters and the fact that a stereo pair would give about 3db more output than a single 87db speaker we have the following outputs at the listening position:

87db = 1 watt
90db = 2 watts
93db = 4 watts
96db = 8 watts
99db = 16 watts
102db = 32 watts

**

Maybe but very unlikely because you assume a perfectly linear electrical input to SPL ratio, but for various reasons that will not happen. For one, The sensitivity (efficiency) will drop as the SPL rises and dramatically so as the speaker get's closer to its SPL limit.
