Idiots!
This is somewhat common during music recordings, too. Not so much low frequency ranges, but using STANDARDISED, properly set up monitors and tweaking things past reference levels so their music can "stand out."
The downstream systems simply have to globally compress everything on the recording to make it work. The out-of-bounds tweaks went for nothing but lowering the overall sound quality of their music.
Guess what - the next idiiot wanted to do the same and we now have a loudness war on our hands. With very few exceptions, modern music recording sounds like hammerd out shit.
They have the tools at their disposal to create the most engaging and noise-free, three dimensional, perfectly separated for clarity, extremely realistic and dynamic music experience for their fanbase and they don't use it. They just want to "Sound Louder Than The Other Guy." ... in a fucking earbud!!
This type of short-term thinking is part of the brickwall I hit when I got out of the business.
Yeah, I hear you.
For a while, I made a point out of having a printout of the standard Dolby curve (the one used for optical sound; this is a few years ago) to show it to every director or sound person visiting my projection booth before a premiere. At festivals, what most of these people wanted was to test run a reel, mostly "to check the sound".
"Have you followed this?" (Me showing the Dolby standard reference curve.)
"What's that?"
"The Dolby standard curve. It should be your sound mixer's bible."
"Er, I don't know."
"What do you hope to accomplish with a test run?"
"Check if the sound is good."
"And if it's not?"
"Change something."
"Not in my theatre. Do you have the time to remix the film before the premiere?" (Stunned silence after this one, usually.)
"Er, no."
And eventually they'd leave.
Then they'd go to the festival management who would phone me, plead with me, etc, and I'd reply that "sorry, I don't do therapy sessions for insecure filmmakers."
Idiots, mainly. And they never learn, except for a few sound guys in the business who know me well and are wise enough to bring cake, beer, or whisky when asking me for a favour. I always test run their reels if I have the time. They know that it doesn't help, but it keeps their directors happy. And, of course, these guys know how to mix a film so usually the sound is great.
I should write a book called "Adventures in the Projection Booth".
