Beemer,
As a fellow Pipedreams owner (I have the original 18s), I discovered something very interesting about this speaker. I was poking around some old CES show reports, and one reviewer found that he preferred the soundstage of the Pipedreams with the tweeters on the outside (apparently one of the demo rooms had them set up this way).
So I swapped the left and right speakers in my system to put the tweeters on the outside, then I 'over-toed' in each speaker so the right speaker faces the left ear and the left speaker faces the right ear.
Now voices are suspended more cohesively between the speakers, dead centered, and the soundstage is incredibly wide. In fact I'm discovering many recordings that I previously had no idea contained virtual surround effects (Q-sound like HRTF effects). Also, with the tweeters facing head on, the dark character of this speaker is corrected. It's an incredible improvement with no tradeoffs that I can detect! It's definitely worth the 5 minutes of sweat to swap the position of these behemoths. You can play with the toe in to broaden or narrow the apparent soundstage. Give it a shot.
