As he is talking about rule of thumb it is not a physics law and it does work as the graphs show on its web page. I also am not able to explain the dynamics behind it. If the VP150 design is holding you back on a purchase, we could use the lay out of the room, at least just the size to possibly let you know if you even need the VP150, the VP100 works very well. . I have a one(VP100) with M22's and 3QS8's sound is great all around, very even.
