In my experience, there is a trade off between placement for bass performance & soundstage. Usually, if you place the speakers nearer the front wall or sit near the back wall, you get better bass but the soundstage suffers.
I would suggest that a better way is to chose speakers with the bass performance for the size of room even when it is placed in the optimum position for the best soundstage.
In my room, the rear of my speakers are 4 feet from the front wall and I sit 5 feet in front of the back wall and on the better recorded CDs, I can hear an all enveloping soundstage which extends to ambience & echos coming from behind my listening position. In a friend's place, where his back wall is further back still, the effect is even better and you really get the illusion of sitting in a concert hall.
Hope this helps.
