More info would be helpful
I suspect that if you provide your room dimensions, along with other pertinent info such as hall openings, bump outs, back wall material (sheet rock, glass, etc.), furniture locations that are fixed for whatever reason, and any other info that would impact the sound, you'll get much better input.
Of course, pictures are worth the preverbial 1,000 words.
General rule of thumb is a minimum 3' from the panel to the back wall (more is generally better for depth imaging), 2' from the outside edge of the panel to the nearest sidewall, and ideally little in the way of "stuff" between the speakers. Also, the dimension between the panels should generally be less than the distance between your listening chair and the front of the panels.
Bare in my mind that the above info is based on my personal experiences of having four different models of ML's over the past 20 years and other members will likely have their own "rules of thumb", which also yield excellent results.
The good news and bad news about stats is that room placement, along with other room influences, have a huge impact on the final sound of ML speakers.
