After RMAF we were up in fort collins and rolling in a New Fostex T500a supertweeter to go "above" some lowthers in 160hz azurahorns. When I say "Above" I am referring to from circa 10KHZ and up and not physical positioning. Traditionally the tweets have resided inside the speakers on a shelf (offset on the horizontal plane). I'll leave all of the discussion of theory out of this and simply state the goal was to align the new tweeters in the vertical plane and let that story play out.
From the side
Essentially the goal was to elevate the tweeters above the horns in the vertical plane for a quick evaluation. We needed about a metre of height and an adjustable base. The original idea was simple barstools and shims but that would require an time wasting outside trip. Christophe suggested tripods and fortunately several gitzos were onsite. What follows is not pretty so women, children and audiophiles should probably not see it but the rest of you need to know.

The entire story if polished, could be an article in a high end rag with names, dates and quotes. The essence of the situation is the quick and ugly proof of concept implementation solidified a concept the core family members understood.
The most important result was a group of friends from far away locations were listening to music together and discussing sound with the same source rather than phoning it in.
