anm, amitnoida: Thanks, guys. You are welcome to visit my place anytime.
Yes, I had to work around a few things at the moment to accommodate everything in my smallish (15 X 12) room. The low cabinet (with glass top) just below the TV is not allowing me to place the equipments below the TV and allow more space for the FS speakers. This unit was completely designed by my wife so did not want to upset her by asking this to be removed and went for a tall corner unit instead to keep all the stuff. And you are right the dark background I had earlier on the wall (on which TV is mounted) was probably better and was my wifes choice. While doing repainting this time, I thought a slightly lighter background/color on that wall would be better as everything on/near that wall is black/dark. But afterwards, when everything was setup, I also felt maybe the darker shade would have been better. Wife surely has a better understanding on color schemes
Regarding the FS placement I have left 10 inches gap from the wall. And so far I have not found any boominess in sound even when I tried cranking up the volume. These speakers come with foam plugs to close the rear (or front) reflex ports, but I have not yet felt any need for those.
