The bulky furniture won’t matter as bass waves are omnidirectional. Place one in the front left corner (try facing into the room, then, try facing the wall about 2 inches away and see what you like better.)
If possible place the second in the back of the room, try both midwall and in the opposite corner and see what sounds better.
I am sure your wife won’t like bass traps so you can get a DSPeaker 8033 II to EQ them once they are placed. Check this out:
