Be careful with the tilt. I found very little tilt worked best for me with both the 1Cs and the 2CEs. Discovered this after setting tilt and noting how much better they sounded when I was standing in front of my chair. I straightened up the speakers until they sounded best when seated. Still some tilt, just not too much.
I would think the 40 watts is plenty unless you are really cranking them.
