You can only use magnetic material to do magnetic shielding. The shield diverts the field away from what you need to protect and ideally you need an enclosed shape but that is difficult to achieve without some serious metalwork....

I use a flattened piece of PSU cover at my desk and it provides mostly good result, image is only very slightly off instead of fully messed up :

Here is without that sheet between speaker and monitor :

Be sure to degauss the monitor after putting the shield in place, it will equalize the new magnetic environment on the mask in the tube.

Hahaha I just ran into this problem the other day actually.

My solution was to move the speakers further away from the monitor, 🤣.

My solution is to use 2.1 speakers - Logitech S200. They cost me €5. Satellite speakers next to the monitor are tiny while the subwoofer sits underneath the desk. Power switch and volume control is on one of the satellites.

Cheap speakers like S200 tend to have a problem with humming, but it is solvable, see http://www.jpf.de/jpf/logitech_s200_humming/page_01.htm.

I would never recommend 2.0 for PC.

As far as magnetic shielding is concerned, perhaps you could glue a metal sheet inside speakers that are close to the monitor. That metal sheet could be cut out from an old PC case. Same trick should work for transformers too close to circuit boards. Metal sheet just needs to be isolated not to short anything.

small tin can cut in half placed over the speaker's magnet do same as original shielded speakers design, don't have to be that tight fit.

I could see using 2.1 for space saving reasons, but there are really good 2.0 speakers out there (AudioEngine for example).
