ECM8000 orientation

[dobomode]

I feel kind of stupid asking this, but what's the correct way of positioning the ECM8000? Should it point toward the source or toward the ceiling? I.e. horizontal or vertical?

Thanks!

Straight up, ear height will do just fine

It is very difficult to reproduce the high frequencies into a large horizontal area, shoot with the microphone to the tweeter's center

Vertical position is the preferred orientation.

At low frequencies it doesn't matter too much, but at higher frequencies, there appears to be a difference. A member here (Anthony) did some tests. See here.
