Is there any way to sheild a RPTV from a sub? I have a Toshiba 42H81 and a Paradigm PW-2200. I want to have my sub directly behind my TV for that is where it sounds best. I don't have enough room to pull the TV out any further from where it is, and I don't have any room to push the sub back. They are within inches of each other. When I put the sub behind the TV, my convergence has lots of drifting from the magnetic pull of the sub. If I move the sub a few feet away, the drifting stops. Is there any way to sheild the sub or tv? (either way I want the same result) Thanks.
