Oh, one thing….because my room is only 8feet wide I have the speakers closer to the wall than I would like, or if I brought them in two feet each I’m only left with four feet between the speakers !
I have a 12' room and dipoles. Because of room configuration and because it is not a dedicated room, I have the speakers at 4' exactly between the centers (so 4' from both side walls) and 7' from the front wall. I sit at 10'. The imaging is very good (it extends a feet from the outer edges of the speakers) and the soundstage is huge. The speakers have acoustically disappeared.
So, depending on how much reflections you get on the side, pulling them apart may have a more of a negative impact on the image and soundstage.
