I have no problem with experimenting and seeing what you like, but to say that using FH is somehow doing something wrong is just bad information...
I get what you are saying.
Dolby has put out guidelines for Top Speaker placement and their maximum angles for Tops are 30 and 150 degrees from MLP. With an 8' ceiling, the spread from front to back is a maximum of 16'9". I am assuming that anything that is within the 30/150 degree placement would render correctly to overheads? The spread is even further if your ceilings are 10' high then the maximum spread is 23'8".
Someone were placing their speakers at traditional height locations because they were not able to put them in/on ceiling but those locations still fell within 30/150 degrees from MLP.
Given this scenario, would the object be better represented by designating the FH/RH speaker locations
as TF+TR in the AVR?
Do we know what the correct angle are for FH/RH?
Seems like if one is using FH/RH then those speakers should be quite far from the MLP?
I understand that their are many people with huge and spacious HT so I can't just generalize. I do apologize for that.
Would it be safe to say that if you have your speakers designated as FH+RH AND
they fall well within the TF+TR parameters then the image will
shrink as the renderer would assume that the speakers are further back than they are?
Just trying to fully understand. Thanks for your input on this subject.

Using FH/RH settings over TF/TR in my setup gives me a more spacious and esp. extended, soundfield with my 3040.
But, I am also using just Height mounted speakers and not in-ceiling
I guess it would depend on the mix content. It seems clear now that FH+RH is intended for those who have long rooms. How long is your room?

If you have a FH overhead pair installed, this sound will be pan-potted right in-between those two. But if you only have TM overhead speakers installed, this same sound will jump to right above your head. The Atmos renderer will not pan-pot this sound between center speaker and TM speakers. That is, if I understand the explanation given by
a few pages back correctly. Did I?
So objects and channels don't phantom? Doesn't seem like it...
OK someone PM me about how to get the damn Test Tones! Arrrrgg.
