I think the speakers are fine in general just 100hz frequency who causing the vibration, I hope Samsung can fix this issue with firmware, otherwise return or give us Q800B Soundbar bar as alternative solution.

I encountered the same problem with the TV. Although the picture quality is impressive, the overall viewing experience is severely compromised due to the vibrating back panel, which can be heard even from a considerable distance. This issue is particularly prominent within the 90-110Hz range. Consequently, I have decided to return the TV.
In the video provided, it is evident that the back panel of the TV is composed of a thin plastic sheet, which exhibits flexing, particularly in the area where the one-connect plugin is located. The vibrations primarily occur in this specific area and also affect the left side speakers. It is worth noting that applying slight pressure with fingers on these regions while playing the same audio significantly reduces the vibrations. However, this is not a viable long-term solution. Furthermore, if I were to opt for a sound bar with features like Q-Symphony, I remain skeptical that the same vibrations would persist at such frequencies, ultimately compromising the overall viewing experience once again.
Considering these factors, I have made the decision to return the TV and explore alternatives such as the QN90B or similar models. While I would prefer to remain within the Samsung eco-system, OLED and QD-OLED options are not currently under consideration.
