I’ve been using the PS Audio recent CD and book for optimizing my loudspeaker placement, but as always I remain curious about the other tools and methods to decide where initially to place speakers. I’ve tried the Cardas method, the 28% method, the 38% method, you name it. But very few of them seem to take the full scope of the room into account - most ignore ceiling height and rugs/curtains, for example. The Hunecke tool takes these into account, plus what I like about it is it allows you to move the speakers and chair around to see the effect on bass frequencies evenness.
Anyway, in doing this I happened upon a combination of seat and speaker position that, if I believe their math, creates a smoother bass range and better looking room pattern. But then the Soundton site (using a similar “pattern map” method - and takes seating height into account) shows it not to be as ideal. In fact, some speaker placements on the Soundton site seem to be in direct conflict with the same placement using the Hunecke site, and vice versa. These sites are confusing, to say the least. 
I’m just trying to eliminate unnecessary movement of near 100 pound speakers, hoping that some sort of empirical online tool can help me as to a starting point. I’ve done it by ear all these years, but REW has shown me the result is not always as good as it could be.
