Quote: "4. Everyone always talks about getting sheilded coaxial subwoofer cable. If I use speaker wire, there won't be any shielding. Is shielding, for some reason, suddenly a non-issue with speaker wire?"

I've had sound systems since the mid 80s, and i've never had any interference of any kind by using ordinary 2 wire cable for all my speakers. it does not mean it never happens.
