If I wanted to shield a Song Center, how hard would it be and would performance be affected?
Adding bucking magnets to the woofers is an easy install. But you would also need to shield the tweeter. We used to be able to get a cup that covered the back of the tweeter. But it is no longer available. With the advent of LCD, Plasma, etc. screens, shielding is no longer as important as it once was. The last time this was an issue for a customer (about a year ago), we fabricated our own tweeter shield.
Do you have an older CRT-based TV? If not, you don't need shielding.
In terms of performance, it won't affect it to any great degree. So that is not a problem.
