Speaker positioning is critical with these and most electrostatics. The key is just to experiment alot because the size of your room and listening position will affect the proper placement.
I think they sound best in a small room with a nearfield listening position (< 10ft away). Try spreading them as far apart as they can go without losing the soundstage. Then, toe them in as mush as necessary toward your listening position. They can actually produce decent bass at moderate listening levels in a small room. Try keeping them 2-3 ft from the back wall. Also, if you have a rectangular room, I think they sound best (better imaging) when placed against the long side.
If setup correctly and played at appropriate levels in a small room, these speakers are exceptional values. However, if you listen to them in anything but the extremely small sweet spot, you will be disappointed even more than most speakers. You will know when you have it right.
