They need to be on stands, tweeters at seated ear height. Lower, tilted back, aim tweeter to seated ear might work better in any room, it changes the angle of reflections off the floor and ceiling, while toe-in changes the reflections off side walls. I would rig up temporary piles of books/boxes, see which sounds better, then go for stands that height.
They have a rear port, so out from rear and side walls, OR, temporarily cover or stuff the port to put them closer to the corners. You gain placement flexibility and you will find you do not lose much bass extension.
Toe-In: To avoid scuffung the speaker bottom and stand top: I would put 3 small ’skid plates’ on the speaker bottoms (2 front/1rear), so the stands can stay at their ’normal’ position’, and the speakers stay put normally, but will move with some effort. play with alternate toe-in, starting with speakers facing the listening chair.
