Doesn’t your LG OLED have built-in works of art to make it look like a picture frame?
I think these OLEDs are brilliant and the very thin panels have almost no effect on sound transmission or reflections. Sony’s version fires its main speaker through the panel.
I can see that my old Pioneer plasma may have some sonic effect, because it is glass faced and so thick and heavy. But really, how much sound do most speakers manage to spray out sideways? Or is the TV panel complicit in re-reflecting sound waves bounced back off the wall behind the listener?
I am thinking about (real) cinemas seating hundreds in a rectangular space, some well to the sides, where a centre speaker behind a fabric screen does make sense for some of the people some of the time.
