Does anyone know if any of the following subs are magnet shielded? AE Ageis Sub Tannoy MxSUB10 Celestion Subs (Any) Paradigm PDR-10 Paradigm PS-1000 I am really after the Tannoy MxSUB10 but i cant get hold of it anywhere. People have said its NOT shielded but I am still thinking of getting it. The sub will be about 15inches away from the TV tube. Will this cause problems?
