My H31 is only about 6'5" above my floor.
The bottom of my screen starts 3 feet from the floor.
The H31 has a mild offset.
I don't know any pro basketball players and I placed a couch under the PJ so no one hits it, but I
would prefer a PJ with larger offsets. I had an H30 before which had a higher offset (I think it was in the 30% range) and that PJ was about 5" from my ceiling, about 8' from the floor.
I much preferred that.
And, with that more extreme offset, one could walk between the PJ and Screen w/o really hitting the PJ beam....that was really cool.
Now everyone has to crouch down when passing through the path.
I can't use one of those many HT PJ's that graduated to zero offsets....people would hit the PJ when standing up in my place.
I prefer the old school way, longer throws (PJ mounted behind you and out of the way), and if not longer throws, at least more of an offset so it doesn't hang down in the middle of the room like a low flying UFO.
But the trends are opposite of my wishes, as usual.
.....where's that 8-track tape I just bought from the goodwill....
