Legacy Aeris speaker placement , two wall choice dilemma

I have a room that is 24ft x 24ft x 8ft, thats right, the worst possible room!. And I can place them only on two walls and both have some constraints. 

Wall 1: 

  Speakers cannot be closer than 8ft or farther away than 9ft. Left speaker is close to a wall/corner i.e 2 feet. 
  Listening position is flexible on this side, ranging from 8ft to 12ft measuring the side of the triangle (from front of the
  speaker) i.e
  This is my current wall!, i.e where the TV is.

Wall 2:

  Speakers cannot be closer than 12ft or father away than 14ft. No wall on the either side of speaker for 4+ ft.
  Listening position is 9ft to 11ft  from speaker(side of the triangle, from front of the speaker.
  There is a fireplace on the left side that prevents the speakers from getting closer without affect WAF factor!.
  Exploring moving TV to this wall, so need to consider carefully.

In both cases speaker i.e the front plane of the speaker is 3 ft from the wall (cannot be more).

Since the speakers are big and dealer is going to help me set it up I want to make sure I do not change my mind after they are setup.

Any comments or suggestion?.
