Hello all. I've got a problem with my center speaker on top of my tube HDTV. I have a Polk CSi3 center speaker connected to a Pioneer VSX-1014. Right now, when I get around -15 db when interference from the spearker starts to mess with the picture. I used to have it connected to an Onkyo TX-SR501 and this never happened. I'm just assuming that having more power running to it has caused this to happen. I've set the speaker to small on the receiver hoping somehow that might help, to no avail.
I know probably the easiest solution might be putting distance between the TV and it. I want to try to maintain the sound field as it is now, and I don't have an east way of putting more space between it and the TV. Is there something I could place under the speaker that might help eliminate this? Will I have to resign myself to spacing the speaker away from the TV? Thanks for the help.
