Although my speakers don't have front or rear ports, and instead have four "slots" in the base which enable some bass tuning by altering the gap between the speaker base and the floor, I do like to have a couple of feet between them and the rear wall. It gives me a sense of the performers being behind the plane of the speakers. Dunno if this is "correct", I just like it that way.
I think that the distance of the listener from the walls is very important too, and this should be experimented with, although obviously there are often practical considerations - for instance the missus may not like you being seated in front of her like you're on a bus I found my favoured seated position is about five feet in front of the plane of the speakers, but it is like I'm driving a taxi and she's my passenger (not that there's anything wrong with role-playing games) Unless you're lucky enough to have a decent size dedicated room, there will always be compromises.
