Rbf-It would appear that with your toe-out that you have you are experiencing more of a direct radiated sound from the tweeters, which may be just fine if you like it that way. It can all depend on how far your listening position is and just how much of the treble energy you want.
How is the bass doing as far as you can tell? While the MWT does have the built-in plinth and bass port on the bottom, you probably would get a bit more bass moving them back towards the wall some.
It looks like you are a bit crowded there with your two racks, TV and gear. Sometimes you have to make do with the space you have, but if you could maybe move your gear rack over to the left, and spread the Ohm's out a bit more and back, you might do a bit better.
I find my Ohm's do very well with a good spread in between the speakers, but not so much you lose focus or get the hole-in-the-middle effect. Great thing about the MWT's is they are so easy to move around, only you will know what sounds best to your ears. Experiment, that is the best way to find the sweetspot, and with the Ohm's, the sweetspot is generally pretty wide.
Enjoy! Tim
