Thanks everybody for your encouraging words. Much appreciated. But don’t forget: It was rick57 of this forum who gave it the final polish.
From some posts I conclude that some people expect more tangible advice how to build a real dipole speaker. I won’t give that – with intent. There are still many ways to skin the dipole cat. My PDF may sound as if I heavily prefer baffle-less dipoles. But that is only one approach – and the most complicated indeed. So everybody has to find his own solution.
But it is completely justified to ask for my own state of art. Here we go. This is my listening situation:
It took me more than an hour to get that part of my “private” room into a presentable shape. My wife calls me a “messie”, I call it creative organic growth.
So please don’t ask when I will tidy up the cable mess on the front wall.
In the front of the picture you see the back of my listening chair. The dipoles are 2.15 m apart (center-center) and it is 2 m from each tweeter to the corresponding ear. The dipole axes are meeting 20 cm in front of my ears.
Two more perspectives:
What my ears hear, looks like this (right is red, left is green):
I credit much of the congruence of both channels to the symmetry of that room side. You may have noticed how the furniture is mirror imaged.
And this is the way how it is distributed to the drivers:
Crossover from the H frame to the mids is 300 Hz, mid-tweeters is just above 2k.
I will tell more about the drivers and why there is hardly any response below 50 Hz in another post.
