They are at the exact same height....
I had to turn the bracket upside down so I could point the speakers a little more downwards than they should have, but there was no problems with that at all...
mine are 6" from the wall and mounted vertically, and the cables are run inside the wall in 20 mm conduit
(bit overkill for QED micro silver tho

)
and as gooner says you can mount them horizontally or vertically, you can also rotate the mounting plate on the back of the speakers 180 deg so you can either see the bracket or hide it….
Very versatile little things…
if you use it at a lower level on the 'good' side you might just have to set up your amp manualy, or use the auto set up if you have it...
The only negative thing I have found with them is the material they have used for the top and bottom of the speaker, it's a kind of rubber, and is a bit of a pain to clean….
But I'm sure it was used for some fancy assed reason…
Unfortunately I'm totally redoing my living room otherwise you could have came over for a listen
(and when I say unfortunately I mean it, wish I never started now

)
