Aerial Acoustics #8 Placement

Does anyone know how the for Aerial Acoustics #8 speakers are in reference to placement and the back wall? I purchased a set yesterday and am setting them up in my listening room. They have a bass port on the rear of the speaker. I have them set off the wall about 2’ away but would like to push them back about a foot or so, so they don’t protrude into the room so far. I’m not wIlling to give up sound quality to achieve pushing them back though. Any experts know how these speakers are engineered to be placed away from the wall or close.
