Another argument in favor of 1 speaker reproduction

On one of the beloved Book of Experiments - Leonard De Vries one experiment title is clearly Sound + Sound = Silence


It refers to what happens when waves meet out of phase. One wave tries to move molecules to one direction. The other wave tries to move the air molecules to the other direction.


When 2 loudspeakers are playing in the same room statistically for every frequency there should be equal number of points in space where waves meet in phase or out of phase.


This is possibly the reason why we might be asked to sit exactly between the 2 stereo speakers. Unrealistic or unnatural siting position. The only naturalness about it is a woman sitting on top of a man or the other way round when both want to be in the middle. And then again you can't be inside the other person's head.


Most of these posts are written while listening to a single Pleiades 2N3053 - Philips AD5046N. This is possibly the best argument. The sound quality.


Is a single speaker the reason why some Juke Boxes or radios sound so realistic apart from the fact they use electron tubes? By the way transistors can sound great too if they are treated like electron tubes on similar schematic simplicity. One reason is no feedback, relatively high output impedance ie semi constant current source conditions. And of course the fabulous gentle overload characteristics of
class A amplifiers. And distortion tending to 0 as the signal tends to 0.


Operation in class A means electrons flowing all the time.
