I've mentioned this a couple of times before on either Tweaks or General, usually to be derided by the mathlexic idiots. You know, the people who will accept all sorts of tweak explanations, but can't do simple math. Here goes.Measure the distance from the tweeter center to the reflective surface (in this case the ceiling), call that measurement A. Then measure the distance from your ear (at listening position) to the reflective surface, call that B. Now measure from your ear to the plane of the tweeters (imagine a line between the speakers, then measure to the perpendicular intersection of that line), call that C
Plug in the values and solve for x.
A/x = B/(C-x).
Measure X out from the tweeter plane and look straight up from that point. That's your reflection point.
This method will work for all first reflection points, and with a little thought, all other reflection points too.
