Hard to tell exactly but I would pull those speakers out some more, at least 5 ft and make sure they are trianulated in a equlateral triangle or close to that anyway and toeing them in until the axis crosses just behind your head and see what happens. BTW, you room is kinda big for small stand mounted speakers but using a sub woofer or two (better) can really fill in the bottom end and flush out tonal response greatly, and it is a lot cheaper than buying full range floorstanders of similar quality. Also your walls a vary bare and reflections are going to reduce your potential for great depth of image.
The TV on the wall is not as big an issue as it might otherwise be if the speakers are out by five feet or so. The difference between the arrival of the direct signal and the reflected signal would be enuf to keep the direct signal fairly pure.
Good luck.........Oh, the obvious perhaps but if the speakers that far out is a WAF issue, you can always put a small mark on the carpet to ID the correct location and when not using the speaker for 2 channel listening you can just push them back toward the wall. One of the benefits of small stand mounted speakers.
