at an orchestral concert there is no crosstalk. Each instrument is producing sound from it’s actual location, each producing a single stream of sound that crosses my head once. If the instrument is straight in front of me, the stream of sound from that instrument will hit each ear simultaneously with one pass.
It’s physically impossible that the sound of a violin coming from the left hits your left and right ear simultaneously and is how we as humans can perceive depth and location of sound Plus, no instrument produces a “single stream” of sound — all instruments radiate sound in a 360 degree sound field that cannot be captured in a single stream. With your logic we should all just listen to one center speaker alone and be done with it. No thanks. But I suggest you bring your theory to the best speaker manufacturers and see if any of them bite. My guess, after they’re done laughing, will be a big fat NO. But by all means let us know how that goes. In the meantime I won’t hold my breath waiting to see center speakers make even one appearance at a high-end dealership or audio show — never gonna happen dude. Oh yeah, and recordings aren’t made or mixed with a center speaker so why the hell would you wanna listen with one? Whatevs.
