@why0why I was concerned about the size of the Double Impacts when I ordered them as well as how they would do in a moderate sized room.
After having lived with them for five months, I would be comfortable putting them in a smaller room and in a 'more' nearfield setup. They do okay closer to the wall, but I'd personally bring them out into the room.
So I don't believe you should have any issues / concerns with the Impacts.
Have you considered the Double Impact 'Rear' 7 Tweeter Pair augmented by a sub(s) for your application?
