Hi Frans

It's odd that just me, you and Nick that are reporting this DSW issue but it is absolutely repeatable. However I've just tried Top Gun Maverick 4k Bluray and the intro is fine for me. Watched first 2 mins. There is a lot of LFE and the DSW cone moves a lot but I don't hear the rattle. I know at least 3 of my blurays do it but can't remember which ones apart from Alita 4k! There is a 6 second sequence from around 50 seconds at the start that sounds dreadful as the volume of the soundtrack at that point is not that loud so it's very pronounced.

Looking forward to a response from M when Nick gives them the details. Think I'll get Passengers and try that one too.

All the best
Bob
