If you take 6 different drivers, unless they have perfectly linear transfer functions, they will all have slightly different responses. If they all have the same input signal their responses should smooth to a more linear response.
Sorry, a complete load of crap.
Are you serious? You add up a bunch of errors and the total error is less than any individual error?
You've already embarrassed yourself with your theory about parallel amps. Might be better to retire now and save face.
