Well, I don't know all the theory/thinking behind it, it came with the acoustic design for the room I bought consultancy for, but I have seem it mentioned online how much more efficient it is in that direction compared to across. It hasof course to do with breaking up the ceiling reflex, but what frequencies it's aimed for and if the slight angle relative the fronts has anything to do with it I don't know.
What I do know is that it's not hyper-critical as I got a reasonably wide range of board size and spacing to choose. I also went the cheap route by just adding one board with spacing onto the drywall, you could have done all board with one resting on the edges of the upper one (that probably has a good and proper english name, but I don't know it so I hope you could still follow me).
What I have noticed when painting is the angle difference you notice when looking across compared to along, so I can't help feel that this somehow has been figured out as a benefit to handle the reflex, but I may be overthinking it.
. But I would not put it past my designer to come up with something like that.
My room doesn't have anything that special in the ceiling compared to some other rooms he has designed, the most special in my case is probably that he could place a false wall about 1/3 in to combat the longitudinal modes. Don't know if I've seen that before.
But in any case... If you're considering doing this instead of a flat ceiling, by all means do! My boards are 3" wide and 1" high approx. and I put them with 2" spacing. (70x21mm, 50mm spacing). It will do more than you think. But you can't get a painted star ceiling and placing atmos in-ceiling speakers would take some extra doing.
Sorry for not knowing more, but one can't expect the pros to spill all their secrets when they do a job, can we? I'm just blessed with having the speaker designer do the acoustic design too, so I know the thinking of both will match.
