If you want the best possible, rotate your sitting area 90 degrees and put active LFR1100s on the long wall. You will experience bass and mid-range Nirvana and a deep, wide, tall soundstage with clear imaging. I know because my livingroom is very similar to yours. I didn't want to move my actives out of my livingroom.
The way your room is arranged right now, sure you could put M100s or LFRs or actives in there but you will not experience the imaging and soundstage they are capable of. It will get loud while staying clean though.
No point in pushing the point with your bride though and risk a scissors lock betwixt her mighty thighs. Then again, that might be a fun way to go!
