I bought an amplified computer speaker set (with subwoofer) for use in my arcade cabinet, and to mount the speakers, I took them out of their cases. By taking them out of their cases, did I turn shielded speakers into unshielded speakers? I've tossed the cases, so I'm not sure what I can do to fix them if I need to.
For clarification, I only disassembled the two speakers, not the subwoofer.
