I have an 85" QN900a and the internal speakers make a loud rattle when the volume is at a moderate level and any type of bass is played.  I've posted a video (https://youtu.be/czQUIT2NHyo) showing the issue with the volume at 30 and adaptive+ volume on.  The rattle is pretty obnoxious and I want to know if you think my unit is defective or if playing sound add mid-level volumes exceeds the capability of the internal speaker.

Update: the TV is not the issue; the problem was that I used the Samsung flush mounting equipment which essentially allows the TV to “hang” on the wall but it appears that puts the speaker section along the bottom right up against the wall. That was the vibration I was hearing: the speakers effectively vibrating against the wall. The installers did not put any spacers to give the TV any clearance from the wall which I’m guessing they were supposed to do. I found some foam blocks in the installation leftovers and put them between the tv and the wall the problem is gone.

Thanks for your input, but I did use the spacers, and have a adjustable wall mount (pulls out/in) and still distorts with bass, along with the non-compatibility with earlier Yamaha AV ATMOS Receivers, just will not allow pass thru 4k, I suppose the 8k is not supported….I just blue $3500 on a **bleep**..>!!! **bleep**…??
