Here's a very old table that's been used to gauge speaker wire applications and it's not just for silver speaker wire, which this site happens to sell:http://tempoelectric.com/cables_speaker-cables.htm
You'll see this table used by a lot of old audio sites and it's probably still relevant unless something's been reinvented.
All the best,
Nonoise
