I have just completed constructing a set of surround-sound speakers. They sound great!!! But the problem I have is in the center-channel causing interference with my big-screen TV (pulling red and green colors to the edge of the screen).
As an experiment, I borrowed a couple of different center-channel speakers (1 from a relative and 1 from a friend), placed them next to my big-sreen TV, and interestingly, there was NO interference at all!
The 3/4" OSB enclosure is using dacron as the damping material. The drivers I'm using are two 8" Bozak all-range drivers and one - 3" Bozak tweeter.
Can anybody recommend anything that would shield the internal speaker enclosure of my newly constructed center-channel?

The most effective shielding material is Mu-Metal, unfortunately it 's very expensive.

Many people find that 10 gauge sheet metal will do an effective job as well. Understand that over time the sheet metal itself will pick up a magnet charge and need to either be demagnetized or replaced

Theirs a product (in Australia at least) called <a href="http://www.dulux.com.au/PaintingYourHome%5CWonderwalls%5CWonderwalls.htm">Wonderwalls</a> this a magnetic paint for children's rooms so they can apply magnetic stickers.
I think its loaded with very fine stainless steel particles.
I have wondered if a coat or two on a cabinet, inside and out, would effectivity shield a speaker?
It would definitely dampen a speaker cabinet as its very heavy, I' d guess it weighs +10kg for 4 litres.
