Hi Bshapperd,
Then you could try to move them closer together and/or put some kind of damping on the wall just behind the speakers. Then play with the toe (probably less toe out since you I ended (after almost a year) by putting some damping material on the side wall.
You can also take a look at some setup in small rooms. http://www.soundscapehifi.com/customer-rooms.htm
Best Regards,
I would also consider sending an email with a picture of you setup to Kevin of living voice shout@definitiveaudio.co.uk He is very, very willing to help customers getting the most of their systems. Sure he cannot appreciate your system with a picture but he can give you some clues about placement.
