>>You say one thing, then you say opposite thing. This zig and zag you do, it is like talking to serpent.<<
I think you must simply not be reading carefully what I write. Maybe your busy or just don't want to; I can't say. But in nearly every rejoinder you've misstated a position I clearly articulated in a prior post. My POV in this thread has been consistent. But I've separated things that I might worry about (which is not as much as you're concerned with) from the realities of others who see no reason to be so precise about their sound. Like this comment/question of yours:
"I am curious as to why you are interested in having sound good in all positions, ie. have bass be smooth while walking around."
An audiophile might grok it, but it's a ridiculous question to a music lover - more of whom Zu would like to sell to.
>>My suspicion is that wide dispersion FRD will improve sound at all positions but make sound worse in listening position.<<
I'm sure you'll find this not to be true if you decide to spring for Soul Superfly. I noted that the new FRD has "widER" dispersion, which is not quite the same as saying "wide." It's not nearly as wide as, say, Definition. It's wide enough. You still can get a focused, toneful, room-minimizing sound in a single listening position if that's what you really want to set up for, which I understand. Many do not want that and won't feel victimized by a beamy speaker.
>>Druid FRD which measures ragged (and I only between above upper bass but below HF where Greiwe loading and essence tweeter should not be issue).<<
I went roundabout with Sean and Adam on this once. They objected to juxtaposing the terms "Griewe" and "loading." It was reminiscent of trying to get a succinct explanation of B3 in their cables. Lacking a more precise nomenclature, we used the combined term "Griewe Model" for the rest of the conversation. Well, it turns out the Griewe scheme has influence on the behavior and sound of the FRD right through its range. Druid really didn't have much Griewe model in it, but just enough to be beneficiary of an idea. Essence and Soul are full Griewe model speakers, Soul being a further refinement over Essence, which you can hear in the nearly same bass performce of Essence in a smaller cabinet, and an audibly smoother more open midrange than Druid or Essence.
