Speakers for my room.

[stfn]

Hello,

I have recently bought my Panasonic P46G10, but am not completely satisfied with the audio. I want to expand a little bit now but I am looking for some input, as my room has quite an odd shape and the location of my tv itself might change the options I have.



Pretty crappy drawn but I hope it works, green line being my tv and the X being the point I sit when I watch tv. What I basicly want is that feeling that you are really "in" the movie when watching, the picture is doing this right now but the audio most certainly isnt. I want to hear stuff around me etc.

Now since my room is rather small, is there any point in going with a 5.1 set at all? and can a 2.1 setup give me the kind of audio that I am looking for?
Any input is very much appreciated, thanks
