You could also potentially center the sub on the room's width.
I've given a bit of thought to this, as I have an empty bedroom that is 12-13' wide and I like the idea of simply floating a
low slung media cabinet between the two walls. That wall is an outside wall so I am also thinking of floating a new wall about an
an inch off the existing drywall. That false wall would be taken right down to the low slung cabinetry, that would hide all vertical
cables running up to the tv.
Hey Tedd, thanks again for the input. Regarding your bedroom wall, I have very successfully chased wires through exterior walls, particularly box to box. It helps to have access to the ceiling above, but not necessary. If you can make that work it has got to be easier than floating a new wall (which also means you have to extend any electrical boxes and switches). Get an electrical wire puller, they are stiff and maneuverable between studs.
From your comment it seems like I should be thinking more about the wiring within my new cabinet. I had not much considered that. The removable top is a possibility, with screws below as you suggest. If I went to that extent, I might just put a couple hinges on the back side of the top, so I could remove the center speaker and just tip it up. Another person suggested casters so I could move the unit easily away from the wall. I get a feeling you folks are messing around behind your equipment more than the average person. Once I am dialed in, I don't think I will be back there very often.
Our current system, which is home theater in a box, does sit on a wider stand. It just barely allows for the two skinny front speakers to sit on the stand, and be vertical on each side of the TV. That stand would not work with my new Polk speakers, which are twice as wide+. This is a good chance to not tie my stand to my TV - which would be bad should we ever get a larger TV. So it makes sense to just build the stand to fit the components necessary, and then have separate speaker stands. I like the idea of weighting the speaker stand with sand, which I can easily get.
Lastly, in my original graphic I show the sub woofer, which in that layout would really be about the center of the ROOM along that wall width. I will most likely move it left, to the other side of the French doors, into the corner of the room. I decided to make a photo, I think that helps. I wish we had a better space, our living room has a whole wall of windows behind the sofa, and a fireplace to the left. There is a hallway to the front door to the right of the curio cabinet. Honestly, the best placement for the TV (and speakers) would be directly in front of the fireplace, which my wife would not go for.
