STRONGBADF1 is correct. Paradigm does offer the choice on their studio 100 towers if you buy black. The CC-570 comes shielded in all colour finishes. The surrounds ADP-470's come without.
The Paradigm atoms could also be bought either way. Not sure if this was dependent on the finish though.
I guess they would not compromise a speaker by adding shielding. I was just curious.
I think I will give the 100 and CC-570 a try. And I might as well get the shielded version. Who knows where those speakers might end up.
Thanks for the feedback.
