I don't think I ever saw a magnetically shielded sub-woofer. But I never looked for one.
The old rule of thumb for unshielded loudspeakers was to keep them at least 1½' away from a CRT TV. How difficult would it be to keep a sub-woofer about 2' away?
Same here I never seen one mag shielded , Just don’t set The subwoofer
beside the tv that’s bad placement.
I’m being forced to throw out my hdtv crt but no one can carry it so it’s sitting there not being used.
