New speaker placement


I'm trying new speaker placements

The speakers are to the R & L of my 36 inch television
and i'm sitting nearfield. My ears are 5 1/2 feet from the tweeters and the speakers are approx 3 1/2 half feet from the back wall (see my system page to get a visual)

I'm interested in getting advice on what room treatments you suggest for this room

Thanks for all the informative replies thus far
I have added a sketch of my room setup including proposed treatments.

The sketch is done to scale
The drawing has been re worked more then once disregard the old speaker placement and areas shaded in grey
No one can tell you where to place you speakers by looking at a picture or drawing of your room. It's a waste of time and effort.

Seriously consider a Sumiko speaker set. See this thread for more insight:

i would be willing to place absorbtion panels behind the television if that helps things.

Newbee thanks for all your suggestions it's very much appreciated
The treatment ideas in your room diagram look like a good idea. The yellow squares behind the speakers look good as well as the bass traps. As for side wall reflections, it seems as if the walls are far enough away that little would be required but it's fun to experiment.
One thing I can say from my experience is that room treatments do make a difference. The room my system is in now had bare walls when I first put the system in. If you clapped your hand you could hear an echo. As I tried putting panels in different places things changed for the better. I also found out you can go too far by putting up to much absorption.
