Townshend shows them placed on top of a speaker that uses the typical speaker design with a tweeter near the top of the cabinet. So placing the Supertweeter on top it is within a few inches of the tweeter. The Moab design has the tweeter in the center of the cabinet, a good 2 feet or more from the top. In this case the closest place is moving the Supertweeter to the side and down to the level of the tweeter.
It is kind of strange though when you think about it. All the objections people have, they are all based on the false assumption the darn things can be heard. But it is made clear as can be from the beginning the output range is well above audibility.

How do you even set the level of something you can’t hear? Level 3, good as any. Plug em in. No change. Not the slightest peep out of these things.
