In theory the perfect placement would be along the long wall with the tweeter 1/3rd into the room and you 1/3rd into the room. This sounds impossible, so next best is 1/5th into the room
Third best is along the short wall, 1/3rd into the room but this too is not manageable so 1/3rd might be possible. This puts the tweeter 5-2 into the room from the window wall; meaning the speakers are in from of your equipment. The rule of thumb is 1/3rd difference between side wall and front wall, meaning the sidewall should be 36 from the tweeter. This leaves 10-0 between speakers. Because the speaker is deep into the side corner the bass will be an issue (too boomy) but its a start point. The couch on the sidewall would remain and a listening chair would be moved to back up to the pool table when listening. This should give you a good presentation.
The further away from the side wall the less boomy, but at some point the distance between side and front wall will become too close to each other and cause other issues in imaging, so you should move away from the front wall equally which at some point will be too far into the room for your use.
Dunlavy speakers are very, very sensitive to placement, and my guess is you have no idea yet how good these can sound. The soundstage should be amazing one you get it right.
I hope this helps some. The key is to get these speakers out of your corners as much as possible. Imaging, separation, bass definition and special clues will all improve.
