Your speakers are just too big for a small (11'x12') room. I doubt that room treatment will cure the problems.
Stand mounted speakers have the best chance of sounding good in your room. There is a wide variety of speakers to choose from such as PSB, Acoustic Energy, Dzurko Acoustics, Totem, Platinum Audio, Coincident Speaker Technology, Joseph Audio, Acarian Alon, Phase Technology, Green Mountain Audio, Von Schweikert and many more in a wide variety of prices.
