Shielding a subwoofer? Monitor is not happy.
(1/4) > >>
bluevolume:
I'm installing speakers in the bezel above my monitor, and am having problems with a woofer that isn't shielded.  The left and right speakers are already shielded.

Is it difficult to add shielding (another magnet I assume)?  It is a fairly cheap 4" speaker, maybe it would make more sense to just buy one that is already shielded.

Green Giant:
Why not save yourself the trouble and just place the sub on the bottom of the cab away from the monitor?  The sub will sound just as good pointing directly at you at the top as it will on the bottom.

There is a sealed box that is perfect for a woofer (there was one there originally) above the monitor.  I've already built the plate out of MDF, so this design decision has pretty much been made.
Zebidee:
Buying a new shielded subwoofer speaker is probably your best bet.  Or pulling one out of something else (eg some old TVs have them) You can buy mag shielding material, but it isn't cheap.
BobA:
You can sheild with anything that is magnetic.   This means steel or any other metal that is magnetic such as tin.  Check a cookie sheet with a magnet.  If it is the cheaper tin/steel type not aluminum it will give you raw material to sheild your subwoofer.   Some people have shielded smaller speaker with tin cans but since yours is larger a cookie sheet is probably your best bet.  Take a fridge magnet along to test it.
