Hello,
I use CWs myself and experimented with several listening positions before settling. I used the golden triangle rule, some call this the cardas method. Look it up and see if that'll help. I am firing towards the short side of my room which sucks but I had no choice. So because of this, bass is a bit too boomy. I am at least 6ft from the corners, speakers are spread 6.5ft from cone center to cone center. 6.5ft from listening position of course. Speakers are 22" from the wall on the one corner and 20" on the other corner from the wall (toe in). That seems to be perfect overall for my situation. Sub sits dead center between the two speakers but slightly back. Hope this helps in your voyage.
