Are your speakers too low?

No, I don’t mean volume or bass. I’ve been looking at some pictures people have posted of their HT set ups, and it occurs to me that a fair amount of people have their speakers set up in such a way that they are a good distance away from the display screen, usually lower than the screen. I know sometimes aesthetics & practicality come into play, but I always thought the idea was to have at least the center channel speaker near to the screen, so the sound would appear to be coming off of the screen.

I use the “phantom center” approach and recently picked up a second hand pair of “floor standing” speakers. At only 30cm high, the tweeter was well below ear height, which I’ve read is the ideal. One of the first things I did was to make a pair of wooden speaker stands to raise the speakers up, and now the tweeter sits almost center of the screen. Sounds that would normally preside in the center channel speaker come right off the screen, and panning effects are spot on all through the spectrum.
Am I way off on this?
