Thanks for the reply. I have been playing around with various positioning of the VP150 and I found out that so far the one that works best is placing it about 9 inches back from the front of the TV and tilted forward aimed at the listening position. Placing it right at the TV screen sounds too forward and detached.

I am not sure if arcing the center speaker will disperse the sound all over the sound field since it is directional which means that the listener can distinguish that the sound comes from the center speaker and since it is aimed towards the listener it will simulate that it is coming from the TV.

I am not arguing with you, I am just trying to understand the concept.
