Dewald thank you -
You have described with more detail what I was wondering about - what you suggest is "phase coherency"
Now that makes intuitive sense to me and in fact I was wondering about certain speaker designs like the Dahlquist DQ 10 where the tweeters are set BACK from the woofers, supposedly to increase coherence and unity. This was sometimes described as "time aligned" in the marketing literature.
On the other hand, there have been several statement speakers where the woofer towers usually seem to be set back from the mids and tweeters.
The trickiest part about the Magneplanars - and Tympanis in particular - is that their bass can be reallly marvelous when set up perfectly, yet typically a bit thin or once in a while even a bit muddy and boomy if not placed correctly.
In my experience, this "dialed in" position usuallly differs from the best position for the mids and tweeters which would give the best air and soundstaging.
Therefore, I am trying to be less concered with time alignment, and more concerned with great bass, a hallmark of my speakers when correctly installed but I am not sure I have heard it yet.
