I use the corners I have for accentuating bass. I don't know about all this suck out business, and acoutical confabulation. As far as soundstage goes it isn't great. I use the set up for when I want to hear something on my Klipsch La Scalas loud. At that point subtleties are lost and you are being moved by the music. If your talking about a corner for a refined speaker I have found it doesn't provide anything close to optimal staging, imagery tonal integration what have you, and would avoid it.
