Definitely a big improvement over my description, thanks!!
Yes, twisted pair will help with induced noise transmission (and I prefer twisted speaker wire for this reason), though this is not a function of the speaker being considered a balanced device, is this correct?

you're not clear on common mode vs differential in that instance
the only way line noise couples to speaker cabling with audible result is through differential coupling - a time varying magnetic field from the outside induces a V difference when it "threads the loop" of the +/- speaker cable wires - just like a air core transformer
twisting wire helps for mag fields that are uniform over several times the twist pitch rate because the field induces mostly canceling V in each opposite orientation loops of the twist - star quad or coax can be even better
but if you measure the common mode V at the end of these high (differential) canceling cable constructions you still measure a V difference induced by the changing mag field that is equal in both wires and gives no output from the speaker
