These might make really good overhead speakers for Atmos use. As long as you don't mind the somewhat larger ceiling print.
These speakers are quite impressive......and that is almost the only place I would NOT use these speakers......and I am a big fan of in wall speakers.
This particular driver configuration doesn't have the vertical dispersion necessary for a good overhead speaker (not to mention the lack of an adjustable angle). Revel makes some excellent in ceiling speakers that have a useful angle to them, and those would likely perform much better because they are not as limited in terms of vertical dispersion.
These would be best for the LCR in a home theater. Even in a two row theater, with the right placement and geometry, each row could be in the vertical sweet spot.
Secondarily, these speakers could be used for surround duties. However, they would not be my first choice for surround duty in a dedicated theater. Why? Well, surround speakers are seldom at ear level. Surround speakers even by Dolby specs these days are a little above ear level.....possibly by 10% or more. Then, especially if there is a riser and more than one row, that angle is exacerbated even more than for the LCR which can split the difference between rows instead of needing to be a bit higher than the highest row/riser.
So, personally, I would choose one of the single woofer Revel in wall speakers for surround duty, in order to have an increased vertical sweet spot. The lower power handling of the single driver two way speaker would be more acceptable in a surround speaker due to being closer to the seated listeners, therefor not needing as much output to reach reference level at the listening position.
