Centre Channel:
I have the VP150, currently it is sitting on the carpet in front of my Samsung DLP (tilted up a inch or so), floor is carpet. Would I be better off building a box under the TV just big enough for it to fit or will that make it worse? All the electronic equipment is in the glass and wood stand under the TV.

Surround Speakers:
I have the QS8 on my side walls. I was wonder about putting sound absorbtion panels on the side walls but I am not sure if it they will adversly affect the sound of the sourrounds.
