I have a very large room in one home (15 x 28 x 11) and a very small one in another (13 x 10 x 8). One can only undo such a small room so much. My best solution is a Netherland product call Zilplex. It is eleven little 1/2" hemispheres that sit on eleven little cradles on your walls. Google that name to find out more.
Frankly, in my small room I could not listen until I added them. They are very unobtrusive.
