Tried 803 Nautilus in my 14x24x8 room, but setup in 7.5' triangle like what you're probably doing, and found that because the lower crossover is a highish 350Hz, the speaker wasn't coherent in the nearfield. I vaguely remember a British review warning that the Nautilus only work 12-14 feet from the listening position minimum. Indeed I preferred the sound from adjacent rooms, where the problematic tweeter/mid integration doesn't screw up the standup/sitdown test. So I guess the power response is really good, but only listenable in the farfield on axis. Sounded like great home theatre candidates, but not terribly musical. Try Revel F30 or Aerial 7b...Thiel 2.3, JM Labs 820? I settled on V.A. Parsifals: great nearfield, AND phenomenal jump-factor. (Don't bother with 804, either...worse!)
