Just telling how bad it sounds, and that it really is the people making and selling the films that is to blame, indirectly says that sound quality does not matter.

If sound quality was important,...

If you want to reproduce this low-freq content, the best way to do it is to use bass-management on all channels.

This will then filter out the low bass from the speakers and reroute all low bass...

The reason they use money to re-mix and actually reduce the sound quality must be because they think this makes more people buy the films.
To me that makes no sense, because those happy with...

From the data presented in the report it can be seen that this is not the case; the x-curve does not work as intended.
