Help with placement of 7.1 surround back speakers

[MartinAndersen]

Hi I am in a dilema. I can't place my back speaker according to Dolby or THX, because of a door in the back wall.

I have attached two photos. One with my Dali Ikon MK2 on wall mounted pretty high and another where there are in line with my "side" surround speakers.

I have a Marantz AV7005 and the manual suggest a Dolby 7.1 setup.

All suggestions are very welcome. Happy new year

Edit: I see now this is a pole.

The Dali speakers can be mounted horizontal and the are build so the point down 10 degrees .

It's also a pole, just to spice it up (-:
