drin - thanks for the feedback. These are the pictures I already had and just came across this particular thread. I did not really think about treatment before. I made a quick drawing our our basement. I don't have the exact measurements right now but this is what I came up with using Visio.
Hope this helps!! The L-shaped room is pretty wide open. The beams I notated in the diagram are just beams on the top. I have the rear speakers mounted on them. The room is fully finished with drywall and the ceiling is finished too.
I would like feedback on how to acoustically treat the room. I am not getting really good sound stage for music. After running EQ on a Harman Kardon AVR 645, while listening to music, the highs are a little too shrill. I have never done room treatment before.
Here is my gear:
TV: 61" HD-ILA P61R1U

Center channel: Klipsch RC-7
Fronts: Klipsch RF-5

Seated position to TV is approximately 9-10 feet
