speaker position to minimize reflections

For the last week or so I have been thinking about how to treat my room to get rid of some of the reflected sound waves from my walls. Since my listing room also doubles as the only living room in the house and the fact that all the walls have openings, and one has windows and a fireplace, I was having a hard time figuring out what to do. Then last night I did some playing around with my center channel. I noticed that if I move it from the top of the tv, to a small 15 inch stand and then point up the tweeter to hit my ears then the couches on the left and right side of my room will naturally cancel out the waves that once hit the wall (the main listing area is two recliners between the two couches). This sounded much much better. Anyway now that I got my center channel sounding great, I want to do the same with my fronts. I found some good 18 inch speaker stands that I will probably buy, but was wondering if anyone has any experience in tilting the front (lsi9) speakers slightly upward? I thought maybe I could get a peace of wood in a triangle shape and use blue sticky stuff on both side to keep the speaker in place. Any ideas?

    There are a few of us here that have tilted the LSi slightly upward. I do the same thing with my LSi 15s. It will not cost you much to experiment around with what sounds best for you. Ever seen hi-end Sonus Faber speakers? They are designed with a slight tilt.

    what did you use to tilt it upward? The only other two things that come to mind are a rubber doorstop and adjusting the length of the carpet spikes.

    Yep, you can adjust the length of the carpet spikes. Mine are about 1/4 inch tilted up. Does it make a huge difference to me? No, but it doesn't hurt any and gives a little more "air." (or at least that is my perception)

    Check out the "mirror mirror on the wall" tip to minimize early reflections.

    Oh yeah, forgot to mention. Do you "toe-in" your LSi 9s? That will help too.
