Sanjay, let it go. You have proven that there has been scientific tests done concerning the human ear, and hearing. I, once again, am fine with that research, but for whatever reason YOU choose not to budge at all on your stance without regard to whats happening IN MY ROOM, and others on the same thread before.
The way I have my rear speaker set up DOES NOT apply to your tests as it is NOT, I repeat IS NOT on the same center line, and there is NO reverse affect, AT ALL, yet you continue to say that it just cant be, and what I hear is wrong. You are more than welcome, as I have mentioned before, to stop by at any time to be proven wrong, IN MY ROOM, not where these tests are done, or in another room where it may occur, which by the way, I do believe can happen.
And to say that a "wisely" placed rear channel wont solve the problem, you are incorrect. Works well in my room, and others too, which you also ignored based on science, in a controlled environment, looking for the phenomena, but why not also give the science behind the ways this phenomena DOES NOT occur?
There are always two, at the least, sides to a story, but you choose to focus on just one to suit your belief. Whatever. I've given my experience, it works whether or not you want to see it, or for that matter, even understand it.
