It has nothing to do with the speed of sound (all frequencies travel through air at the same speed) and everything to do with phase cancellations due to different wavelengths causing signal peaks to occur at different times at a given distance from the driver. Here's a good description.Without wanting appear naive and showing my ignorance in this subject
So let me try to fathom this
If sound travels at 750 miles an hour or 1100 meters per second how do you hear the relative distance of placement of the drivers?
Or is it too says that the orchestra is set up so that the instruments with the lowest pitch are relative in distance too the highest!
I am sure there must be a reason for time alignment
Would someone be so kind as to elaborate on this issue?
