All horns are not alike ,Tractix , Exponential , Bi-radial , Wave Guide , Constant Directivity , Elliptical all have different sweet spots some are very focused to mere inches some are not as focused & have quite a wide sweet spot .
Many have reported that their LaScala & Khorn don't present proper imaging unless they are 20 feet apart & the MLP is 20 feet back .
the PDF you link to refers to just wave guide horns & as I state not all horns are alike in their dispersion patterns
Respectfully I don't understand what you disagree on with what I said .
I have at one time or another each of these horns :
all have vastly different dispersion patterns & vastly different sweet spots
I like the Elliptical the best as there is a wide sweet spot @ the MLP , plus the added benefit from not being reflective off the ceiling & floor

there are other articles he wrote about his speakers and why he like the taller Big Cabinets so the mid horn was at ear level. Notice most of the HT speakers are tall towers now.
My "disagreement" was only meant to be a point for further discussion (ergo, the "wink"), and to present an alternative viewpoint which, for me, has engendered a profound improvement in the breadth of my speakers' sweet spot.
Four months ago, I replaced the twelve-year-old Klipsch SF-2s that were my fronts, with a brand new pair of SF-3s (the SF-2s are now my surrounds). I had never realized how sharply focused the horns on the SF-2s were, until -- as I mentioned -- some years ago, I toed them in, so that instead of facing straight ahead, they were pointed directly at my MLP.
When I first got the SF-3s, I toed them in the same way as the SF-2s had been, and found them to be just as sharply focused. Then when I read the article that I linked, I changed them to the toe-in configuration which I described, and found the result to be infinitely better.
Looking closely at Fig. 3 and 4 in PWK's Speaker Placement Guide, you can see that the mains are aimed just a bit to the outside of the listener's ears, so that their focal-point crosses slightly in front of the MLP... and his discussion seems to corroborate the thinking behind my own system's setup.
Needless to say, not all speakers produce identical sound-dispersion patterns.
So again, the point of my post was merely to suggest a front-speaker arrangement that I personally found to be extremely helpful -- and which produced a HUGE improvement -- in the hope that there are others out there who might not be aware of the potential benefits of what I will call "exaggerated" speaker toe-in, and wish to test it out for themselves.
By the way, Louis... just to clarify, "B 26354" (not B 26345) is Rick Deckard's Blade Runner badge number. Ergo... my avatar. Edited by B 26354 - 7/30/13 at 1:12pm
