setting up non martin logan speakers as surround

[Erobpaint]

I have a set of sequels for my front that I just got and I am in heaven., but cannot get ml for the rear yet. I could if i would like to live somewhere else, my wife would throw me out. You all can understand that. My question is how do I set up my pair of klipsch rear speakers with the fronts. They have to be set up behind me. Do I put them out of phase or set my processor for them to be further behind in feet or closer. My B&K works on feet for delay.[email protected]
