It's more about what's similar than what's different. All three are meant for carrying VHF to SHF frequencies, not baseband audio. Why not use real audio cable? And if you're going to use the speaker wires to drive the sub, a line level signal isn't needed.
Ease of use. I can make BNC-> F or BNC -> RCA cables for the various endpoints easily enough. I personally hate F-type connectors and wish they'd all diaf. The one thought that is just now occurring to me, though, is longevity. I highly doubt I'm going to live here forever, and whoever owns this place after me is probably going to look at those connectors and get all confused.
Hence the problem. Once more you're choosing RF parts that aren't appropriate for AF use. What's so easy about tracking down oddball stuff like BNC wall plates and making custom cables that are worse than normal ones?
Well, crap. The sub run is 52' or just shy of that. The only other RCA run is for the audio out of the Wii. I believe that one is 36'. So does the Belken cable mentioned first qualify as "Balanced pro spec"? I suppose for just the three runs it isn't all that cost prohibitive.
Belkin does make several types of STP cable for audio balanced line use. I don't see it mentioned here, but it's readily available in bulk or with various combinations of XLR and TRS connectors. You'll still need a balun at each end. But since running the speaker wires to the sub will eliminate the need for any other signal source, you're good with a pre-made "zip cord" style stereo pair with molded on RCA plugs for the Wii, provided you can find them in the right length.
16AWG2C good enough?
It's good enough, sure. My point was that when it comes to speaker cable, there's no such thing as too little resistance. If you welded a dozen gold bars end to end and sold it as "the ultimate speaker cable" I'm sure that a few high-end mavens would pay twice the going price for the gold just to have "the best".
