Judging from your question in the comments following Robert Harley's review of the Salon 2s, I'm guessing you haven't grown any in the interim and that you still haven't fully resolved your vertical axis response concerns to your satisfaction. :)
I will say that while auditioning for the speakers that eventually became my Salon 2 purchase, I listened to a pair of Legacy Focus SE that sounded quite nice when seated in the sweet spot. They then lost 50% or more of their high end response when I simply stood up - so your concerns certainly have merit in general. I have not noticed any such phenomenon with the Salon 2s, but neither have I done any detailed listening to them at various heights and/or distances to ascertain any differences in tweeter output.
There are a couple of reviews out there discussing the Salon 2s off-axis tweeter response, but I assume these are along the horizontal axis. Stereophile measured response as essentially flat at +/- 10 degrees (albeit at a distance of only 50 inches), while Sound and Vision reported tweeter response with only a -3 db loss at +/-30 degrees. Given that the tweeter wave guide is not round but rather oval, I don't know how to extrapolate the horizontal results to the vertical. You might find it interesting that the Sound and Vision reviewer moved them out only 3' from the front wall, not 5'.
SoundStage Network did in fact measure the Salon 2's up and down axis response...and then averaged those results with horizontal axis and directly-aimed response and only published the average. Maybe you could contact them for the stats.
My pair are spread 11' apart. My listening spot is 10' out from the center of a line between the speakers, with the speakers spread just slightly wide so that they are pointed at a spot about 2' behind me. This sets up a wide soundstage in my room but is outside the ideal nearfield distance Raquel describes.
For the purposes of your inquiry, I assume you want to be within 12' of your display (or closer if possible). Tomorrow I'll move them a little closer together and out into the room and from there into various positions to see if there's any change in what I perceive the tweeter response to be in the different locations, and then report back.
