New speaker placement

I'd agree with the previous posters on having some treatments on the front and back wall. From the pictures of your system, it seems like your speakers are quite far from the side walls. If that's the case, treatments on side walls may not be too necessary. I would think the biggest impact would be the front wall and placement of speakers. Your TV at the middle isn't helping too much and I would concur with Newbee's idea. It depends on whether you would be willing to sacrifice aesthetics by placing some absorption panels behind the speakers and/or TV. As for the back wall, you can experiment with either diffusion(tall CD racks or book racks will do) or absorption.

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:
