Yep, you're on the nutzoid edge. :-) I wouldn't worry about volume as to what size wire to use. Think more in terms of frequency. The lower the frequency the less it matters what wire is used. I have used in the past 14 gauge romex for drivers below 100Hz and rat shack 30 gauge magnet wire for tweets. Keep experimenting.
Tri-amped sys. speaker cable gauge question
In a tri-amped stereo system, would it be beneficial to use different gauge wire commensurate with the power requirements for each set of speakers? For example, would it be better to use 10 ga. for the subwoofers, 12 ga. for the mids, and 14 ga. for the tweeters? Alternatively, is there a benefit to using 10 ga. for all speaker cables (cost not being a factor)? Details that may or may not impact the answer are that the active crossover in use allows independent level adjustment for each range and the amps in use are all from the same manufacturer having different power ratings (120 watts/channel, 60 watts/channel, and 30 watts/channel for the subs, mids, and tweeters respectively). Also, the speaker cables to be used are DIY using Cat 5 cable and this basic recipe:

I'm going with the answer is yes.
