I haven't seen one of those devices in a while, but seems they need more depth then the box in question has.

Yes, I think it needs more depth.

They dont need boxes at all, tho they are ~1.5" deep

I know they don't need boxes, I was trying to point out they likely are deeper then the box in the OP though, which is something one should only want to use because of a shallow wall cavity to start with.
