You can ask Soliloquy directly, but they told me that the degree of toe-in will effect the bass response of their speakers. And I found this to be true. I settled on approximately 10-15% of toe-in. I also had the speakers at least 2.5 feet from the back wall, measured to the back of the speaker. Are yours broken in? I'm guessing that your description of 'boomy' means that they are. The Soliloquy's don't sound well balanced until they have at least a few hundred hours on them. Five hundred is where they really open up.
It sounds like you might want to do some room treatment as well, but obviously I'm not familiar with your specifics--and I'm not an expert in that regard.
All the best,
Howard
