I'd have them along the short wall facing down the length of the room. they aren't near field monitors (say like LS3/5as) and do need space for the horns to integrate with the SW. Don't worry about them being in the corners (I have my Duos in the corners of my room). The soundstage on AG horns extends significantly outside the speakers.
Your room will be fine with the Unos (Nano) - probably a bit samll for the Duos though.
