Even if I had the money and desire for a setup like that, I would not want a high audio range in media because I hate loud noises and am very sensitive.
In my opinion the big explosion can be a little bit louder than the footsteps but there doesn't have to be a huge difference. I'll sacrifice some realism for my eardrums.
And why can't all dialogs be about the same volume either?
Sometimes there's also a random high pitched buzz in the background that's louder than anything else for one whole scene. How heard would it be to just remove that frequency range or maybe see that it is louder than every other scene?
