Speaker Positioning

Forgot to mention 7 ft apart might be a bit much considering your only sitting 7 ft away, its basically like wearing headphones at that distance, I would make them about 5 ft or 6 ft apart instead which will help center the image more already and consolidate some energy to the center of the room, cause you are probably overshooting any chance of center image that far apart and sitting so close, and then follow the quarter inch toe'ing method from my previous post.

depending upon your taste, you might try towing the speakers out. mark the position with masking tape before you move the speakers, so you can return to the original position. also considering elevating the speakers.

I would keep bipolars away from walls and especially the rear wall....so as to delay the reflected energy. It seems the brain can handle secondary reflections as long as they are not "crowding" the primary signal (you will sense if this is happening as it sounds "claustrophobic").

In essence a biploar is like having a virtual second set of speakers placed behind your rear wall at the same distance as your speakers are from the rear wall => you actually hear four speakers ...really I am serious!! Therefore toe in or out will do very different things compared to a conventional speaker. For example, if you toe in the real speaker then your "virtual" speaker will toe out!!! That is why MrTennis suggestion to toe out is an option worth checking out...as it might give you a very wide soundstage whilst maintaining a solid central image.

I suggest you try to sit at about 1.5 times the distance between your speakers and well away from any wall behind your head.

Thanks to all for the informative and interesting responses. I'll experiment with trying to move them a bit closer together but the audio table that holds my gear is between the speakers. They are a decent distance from the wall but I cannot move any further back. My listening chair is against the opposite wall that the system occupies. I have always flirted with the notion of removing that wall and making my place into a large studio. I could move further away but I don't know if the structure of the place would allow it and of course the landlady would have to be told. As great as a relationship that we have I don't think it would wash. Hurts being poor.

Once you have been satisfied with the new speaker positioning, for your room I'd suggest to consider acoustic treatments. I had a listening room that was helped quite a bit by first reflection point treatments and corner tweaks as well. My speakers were not bipolar though.
