Diffuser or absorber behind listening position....and is it worth doing??


I am a relatively new to serious two channel listening so I don't have a lot of experience to rely on. However, from what I have read on this site I do feel pretty confident that improving my room acoustics via absorber and defusers panels will be the best way to improve SQ at this point. Unfortunately, because my listening room doubles as my living room the only place I can only use panels ( no base traps) and only behind my listening position.... hence my title question. What say you.....will I benefit from adding diffusers? Or should it be absorbers? or forget it and be happy with what I have. (which I am.... )

Here are some room and placement specifics:
Room 12 ft by 18ft 
Speakers (ribbon tweeter) on Long wall with large window with wood blinds on right and drywall on the left
Speakers baffle are 32 inches off front wall and 48 inches off both side wall and are 10 ft apart with a 6x9 rug.
Sitting position can be either against the wall or 2ft off the wall (just slide couch forward....which I do because sound stage and imaging is better).

My main goal is to improve imaging and stage. If it is worth doing, would there be any other benefits? Also,
could you recommend how large a space should the panels cover..... how thick panels should be?

Thanks in advance

Change the wood blinds to heavy drapes and you do not mention the floor but that can have a detrimental effect on the sound especially if it is hardwood, ceramic, or some other hard surface. If it is a hard surface floor try a heavy area rug in front of the speakers. With just these small tweaks you will have a much better sounding room.
