Ok, Now we are on to something. You have plenty of length in your room.
I believe that you have your audio system on the wrong wall. You will need to be open minded about my suggestions:
I know it will be a pain in the neck to move it and re setup that sub, but I think it will be worth it.
I'll quote my Father, he's still alive, but he used to say; "Son you need to get your priorities in order."
I know this is harsh, and I'm sorry that I have to be the one to tell you this right now, but your priorities are your TV and your Fireplace.
If you want to make your Audio System your priorities then you have to move your set-up.
1) Your speakers can flank the fireplace and place them about 4 feet out into the room, then you can consider a front projector and a motorized pull down screen above the fireplace, and put it up when your using the fireplace.
2) You could also leave the TV where it is and buy a second pair of movie speakers to flank the TV, and move the Audio Speakers to the sides of the fireplace.
3) you could also put the speakers opposite the fireplace, along the the window wall in conjunction with the TV, and buy some curtains to cover the windows. Then buy a couple of swivel chairs, or a couch the offers seating on both sides, like they have in hotel lobbies, or a sectional couch that you can move around.
You could also probably consider some stick-on acoustic ceiling tiles for the wood ceiling.
Well, there you have it.
