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.
**Nothing bizarre about it. It is standard practice.
Would it not be easier to shield
it with some mu-metal?
**Nope. A bucking magnet is most helpful. Try and find some mu-metal. After
you do, try to form it into the required shape, without destroying it's
properties. All in all, it is a dumb idea.
