Hi,
A thought just came to my head. In the interference theory, if two waveforms are in Sync, the interference is constructive, the amplitudes add up and doubles, but the power increases 4 folds. However in places where inteferences are destructive, the amplitudes cancel and they will become zero, and power reduces to 0. this ensures that power is redistributed and conservation of energy happens.
So in the situation of Stereo, the person who hears a center figure, example of a voice that is balanced on both channels, would he hear them as 4 times as loud?
If there was 2 speaker identical speaker drivers at ear level, one on the other like a line array, the amplitude would double too, and would cause them to e 4 times louder.
Therefore these 2 speakers a side, 4 speakers in total. The loudness should ideally go up 16 times. Would that make much sense?
Thanks.

See pages 17 and 18 of my NFLAWP to calculate efficiency and sensitivity gain. The change in overall SPL is a function of the number of drivers and how you connect them.
