Qusetion, how far away from the ceiling/walls do the qs8's have to be?

And when using the FMB, how low do they hang? Can someone measure their ceiling mounted qs8's from the ceiling to the bottom of the speaker?

TIA

Hi!
21/2 to 3";10 to 11" respectively.
The best idea is to call Axiom, they have an amazing C.S.
