Hi Nick,

I would tend to agree as in my experience it's only certain sections of a few films (Alita at the start is one). I reduced the DSW size to 30 from max so I don't get the effect on any films, although it will re-appear if I listen above 75.

As I mentioned if you feel the cone underneath when it happens the travel is very large so it's beyond what it is capable of I think unless it's hitting the floor and that is the sound!

Regards
Bob
