Planning to build a couple of Jack10s with passive filters, but having only biamped before and being from the UK, I wanted to double check what is meant in the plans when it says to choose 'the smallest gauge available' for the inductors... does this mean the lowest gauge number (i.e. the thickest), or the gauge that is physically the smallest (i.e. the thinnest)?

my pocket is hoping for the latter but my gut says it's probably the former...

The smallest wire diameter. Wire gauges are like shotgun gauges, the smaller the number the larger the bore.

I see that for a piezo tweeter array, 28ga is recommended in the plans (J12L). The only reference I see to wire gauge for the low end is that the inductor should be 14-18ga. Should the wiring for the woofer be in this gauge range as well?

I'd use 12-16ga for the woofer. The tweeters are pretty much anything you have....I prefer something bigger than 28ga as that's pretty danged small for soldering.

I like 28ga for soldering to piezo lugs as it takes minimal heat.
