Ok so my apartment living room is layed out in the attached picture. The room is approximately 16x16, with a vaulted ceiling going from right to left (left being the higher side, probably at about 12ft)
The room is open to the left, where the kitchen and dining area are. The right wall is primarily taken up by a sliding glass door with floor to ceiling vertical blinds.
At the moment, I am using my old TV stand, which does not have room for the center speaker, so its sitting in front propped up slightly for the time being. This eventually will move into a new entertainment center where it will sit below the TV. The new TV stand also will be a bit narrower and will fit into the corner better, allowing me to move the front L and R speakers back a little bit.
The subwoofer actually is arriving today, and that is the most practical location for it, I have not been able to test the sound yet.
The surround speakers are my biggest gripe because I can't really get them where they should be without having one in the middle of our hallway. I figured this would be the best location for them, sort of in more of a presence position than surround.
At the top of the picture is our fireplace, as a college student, I don't forsee using it much at all, but I am looking forward to moving that FL speaker back a little ways off the hearth.
My question to you is what do you think would provide a good subwoofer placement for the room? I figure my two best options are where I have it in the drawing, and maybe behing the middle seat. But if you see anywhere else where it might work, let me know.
Also, I am willing to rearrange my furniture if it would mean having a more ideal surround set-up. Eventually I will be upgrading to a Plasma/LCD TV, and there is a very nice spot above the fireplace for one

. For the time being though, this is what there is to work with.
Additional info, the front speakers are floor speakers, about 3' tall (Infinity Reference 2000.4). The surround speakers are on 30" speaker stands so they are the same height as the fronts, and have clear projection over the little end tables.
Any comments and suggestions are greatly appreciated!
