I am planning to build a centre channel speaker box using the same type of
single woofer/tweeter drivers as the surrounds. Was wondering what is
required in the way of shielding. The CC would be sitting about 6" above
the
54" HDTV. Thanks

**A 'bucking' magnet, of approximately the same magnetic force. Apply it to
the existing magnet. Then, cover the whole magnetic assembly with some soft
iron or, preferably, mu metal. Better still, follow Graham's advice.

That's some really bizarre advice. Would it not be easier to shield
it with some mu-metal?

Have you seen the price of mu-metal ?

If you bend it, the magnetic properties get f***ked anyway.

Proper shielded drivers are designed with a different style of magnetic circuit.
Better to address the problem at source rather than try to fix it.
