    i was talking to a polk rep today about magnetic shielding as i am thinking about turning a bookshelf on its side and using it as a center, and the rep told me there are degrees of magnetic shielding. bookshelf/floostanding speakers have a second magnet attached to the one that drives the speaker, which dampens/cancels the magnetic field of the speaker. center channels have both the second magnet and a layer of metal placed somehow in the speaker (not sure on the details) to further dampen the signal since it is usually placed right next to the TV. so... i would suggest moving the bookshelf speakers farther away.
    also, it might not be the speakers, depending on the type of TV. some of the new-fangled TV's get funkily colored after they are moved, and clear up after they are left off for 30 minutes. might want to check you TV manual.

    Sometimes the bucking magnet might not have recieved it's opposite polarity charge properly. In this case, Polk would probably be willing to assist you with replacing the culprit driver. I would call Polk CS and see what they say to do.
