Room acoustics needs help.

Since I moved into a new house, my new living room sounds terrible. The hardwood floor is all throughout the house. I believe it is the reason for the bad sound quality. I made some wall panels and hung them on the wall behind the speakers, and on the side walls it help a lot. However, the sound of the music and the voice of the singer seems to be way behind the speakers and not extended. Looks like there are reflection or deflection somewhere in the room. I wonder if an area rug, 100% wool will help extend the music. My room size is 14'x22'speakers are placed on the short wall 4' away from the back wall, 2-1/2' from side wall, and 9' from speakers to listening chair. On one side wall have a hallway in the mildle of the room, and another one at the end leads to another room. Other side wall has 2 windows, and wall behind the listening chair has a 8' wide bay window. Any professional help will be appreciated. Thanks.
