I will have to take some measurements on my room and try to seat the MLP to the closest point on that ratio and then I can experiment more with the distance from the front wall for my mains. As a side note, I had a lot more imaging when I had the towers further into the room. I still have that positioned marked and I'm curious how close it is to the suggested ratio.
