Considering that a fair bit of the sound design involves a lot of bass at 30 Hz, that's quite tragic. Can they get the academy to revoke the academy award(s) for sound as I seriously doubt that the theatrical track was filtered that way.
All of this suggests that they did a completely new mix for the Atmos home release. It would be nice to know why they filtered the bass. Was their sub system not up to the task? Were they trying to avoid distortion on weaker systems? Did someone just apply those filters because of something they read online and shouldn't have believed? At least, it sounds like the rest of the soundtrack is much better. Perhaps I could even enjoy it now, except that I really didn't like the movie either.
Well; since the sound design of the atmos 7.1 is different from the dts 5.1, it will not sound the same no matter what eq.
@maxmercy has a very valid point with "careful what you wish for".
Overall, the 7.1 sounds better, but the 5.1 has more impact in at least one scene.
With the low freqs retrieved, there is a lot more low frequency content in the 7.1.
The low frequencies can be brought back, but if different sound effects are mixed in with different level, that can never be changed, and I am fine with that.
I suspect the overwhelming 20hz drone was never present in the theatrical.
We know the dts 5.1 is a near-field re-mix they did on a mediocre system, as they presented an article on the web describing how they did this "improvement".
The 7.1 is also a re-mix, but it is quite clear they did not do all the destructive changes that makes the 5.1 sound too loud and kind of strange on dialogue.
My guess is that the 7.1 is more close to the theatrical, maybe they did not change much at all.
