The Soundstage measurements for the Druid are irrelevant to actual performance. The problem is they followed a standard practice of suspending the speaker in free space for the test. The Druid MUST be used on the floor for the Griewe principle to work. The actual performance is much more neutral/natural than that since-discredited graph.
As for beaming, Druid is more directional than, for example, the more expensive Definition, but it's not so restricted as, say, a Quad ESL-57. In practice, the area of holographic focus is about 3 people wide, but the sonic impression doesn't fall off a cliff outside that window. They are quite listenable throughout the room.
