Is it even possible to set up a system in 12x12 room?


I am moving next week and there is an extra room that is 12x12 with 9 foot ceiling. This will not be my main system but I have an extra gear I would like to use. I have never set up a system in a square room and definitely not this small of a room. I have a couple pair of 8 ohm 87 db monitors that go down around 40 to 50hz and a pair of 6 ohm 87db floorstanders that go to 27hz with ports in the front. I have a el84 tube amp that is 25 watts and a 150 watt solid state amp with a tube Preamp. The couch will have to go directly on back wall and may be able to pull speakers 2 to 3 feet off front wall and maybe a foot or so off side walls. Is there anyway to make this enjoyable to listen too? I know I'm going to have to treat room but where would panels perform best or am I wasting my time?

If you are able to set up a nearfield listening position...you probably won't have to turn the volume up as much as if you were 10' away which will reduce some of the unwanted reflections and give you a better overall sound...this would be a good place to start because the investment is zero...and then if you aren't happy with the sound you can start exploring treatments.
You might consider setting up the system on the diagonal. Will the couch fit that way?  I know of several users who get better results that way in square rooms.

Nice to have a 9-foot ceiling!
I think you can get a system together that will sound pretty good if you accept limitations in terms of bass response.  The biggest issue I have run into is not being able to get adequate space between the speakers (9' minimum is ideal) and distance from back wall. 

Many speakers have minimal issue in terms of near wall placement.  If you can be 8' away from speakers that are 9' apart and are 2' from the back wall...you should be in a good spot.  
My biggest concern is couch directly on back wall, I would think I need to pull it out into the room, am I wrong? Problem is there's not much room to pull couch into. I'm very glad to hear many have success in smaller than average rooms, I do feel better knowing that. This system was in bigger room and speakers disappeared. if I place myself near field will I hear music coming from speaker or will they disappear. When I place myself near field with this system in bigger room I hear the speaker, there is still imaging but not the same type of sound stage.

Paul,

I had to relocate my system into my daughters old bedroom which is 12x12x8. My speakers are placed about 3-1/2 ft from the front wall and 3 ft from the sides walls so the speakers are 6 ft apart. My sitting position is about 1-1/2 ft from the back wall and approximately 6-1/2 ft from each speaker. I installed wall to wall carpeting. 
I use GIK bass traps on the front corners and placed 2’x4’x4” panels at the side reflection points that also help with the bass. I placed 2 2’x4’x2” panels behind my sitting position half way between the ceiling and the floor.

The results are better than I expected. The bass is tight without sounding boomy and the room is still lively without sounding bright. I tried extreme toe-in but it caused the bass to sound boomy.
If you have any question please send me a PM. Ron
