Stereo image focus was fairly good, the phantom center image wider than usual but not unduly so. In general, I obtained good image depth and transparency from the Duo. Image stability was very good, and notably unaffected by sound level. I heard less room-excited ambience; the sound was clearly more directed (as horn theory teaches us) toward the listener, with less room contribution than usual in the mid and treble. This kind of room drive took a little getting used to; I consider it a significant component of the “difference” felt to exist between the horn and direct-radiator technologies. Of course, in some rooms with awkward, asymmetrical dimensions and acoustics, the horn speaker will provide a more consistent and more accurate sound at the listening position because of its controlled directional behavior.
