OP, if your question is why can’t we create a single speaker that creates stereo like sound?
my “lay” answer would be because stereo effect happens when the sound is coming from at least 2 different physical locations. So a single speaker alone cannot do that. BUT, my hypothesis is that if a single speaker PLUS a room capable of isolating and reflecting sound, then a single speaker could theoretically bounce a sound of the walls. But here is the issue... sound waves coming directly at the listener would most likely hit the listener’s ear before the reflected sound. Anyway, I could be WAY off but it was fun to think about.
I’d love to hear an answer from a sound engineer or anyone with actual scientific knowledge about the topic... unlike me. 😊
