dadork, the most important concept is to make your speaker's environments symmetrical. That does not mean the room has to be symmetrical. If one speaker is in a corner the other should be also. The farther away you maintain symmetry the better but you can loosen up after 5 feet. if at 7 feet there is a window on the right there does not have to be one at 7 feet on the left. After 10 feet the more irregular the room the better. You are trying to keep both speakers as efficient with as close to identical frequency response and radiation pattern as you can. In a really bad situation digital room control can be a help but it is always better to give the speakers the best environments you can. Some speakers are more tolerant of aberrant situations, planar dipoles in particular. You can throw them anywhere and they will image pretty well which is what I think draws a lot of people to them. In my book it is all about the image. I use DSP and I can change the tonal balance of the system any old which way but I can not make a system that is set up poorly image. I can improve it a little maybe but it will never be as good as the best.
Speaker set up and IRREGULAR rooms.
For some odd reason a closet was built in my living room. It juts out from the right side wall ahead of my listening spot. It actually limits where my listening position can be. Future plans do include removing it but in the mean time I have a question about positioning of my floor standers. Because of the closet it effectively makes it so that if I were to draw an imaginary line from the face of my closet to the back wall I'm at 11.5 ft. room width. Past the closet and to the right of the speaker it opens into the dining room. What does anyone think about placing the right speaker outside the imaginary line effectively in the area leading to the dining room? it is still clearly fully visible though I'm sure I'm getting some of the output bouncing off the side wall of the closet. I ask because it allows me to get a lot more distance between mains. I have Dali Opticon 8s and placed as so they sound pretty fantastic.
