New living room project!

We are going to move to the new house and as been complicated to define the disposal of furnishes, sofas and... Audio!

here it is the first sketch:

the TV is in the front wall with the central speaker on top (or underneath). the projection screen is in red behind the TV.
the back speakers are in the wall behind the sofa.
the pink spot in the sofa is the "sweet point".

in the corner beside the right back speaker is the air conditioning that cant be moved.
the subwoofer doesn't appear in the image, but it is supposed to be between the TV and the fireplace.
the hi-fi and tv stands aren't in the image.

what do you think?
suggestions needed.
