I have four of these as Atmos speakers. I really like them. I've since upgraded my fronts and am in the process of upgrading center and surrounds. No plans to change my elevation speakers. They are out of the way, sturdily installed, do a great job, and I don't think anything in it's price range would do a significantly better job for it's purpose.
The one thing I will say is I recently got my first experience with Atmos in a dedicated theater with in-ceiling Atmos and I feel like it really does help to have them coming from more overhead. Mine are setup as top front and top back. Mine are on the side walls. If I can one day update and get in-ceilings, I would consider it.
My guess is you should set crossovers slightly higher than surrounds and don't higher the gain too much on them.
Glad you are enjoying them!
