With "low ceilings" I would stay away from anything too tall or pointing upwards. I love Vandersteens in a room with high ceilings but never with a low ceiling. How far away from the speakers will you be sitting? If you are 10-15 feet away, it shouldn't matter. At 20-30 feet away you will be getting the ceiling reflections in between the other music.
That's a case for more conventional cabinets and drivers?
