IDK what you mean by audience sitting at the center and atmos making sense.
Before I type a response I just want to ask if you have a system setup for atmos in your home. If we are talking what makes sense we need to be specific. There are good and bad mixes in everything. There are atmos mixes where it sounds like you are standing right at the position of the conductor. There are mixes when you are in the audience and many other types. What specific track or album are you referring to where cymbals play behind you?? Your post is written like you don't have a proper atmos setup or just very little experience.
Do you realize that most mixes start at the microphone into multiple tracks before they get compressed into just 2 channels for stereo? The don't start in stereo at all.
