uFonken flat-paks

Thank you Dave, that explains why an experimental box I built for them sounded so much better with TP loosely stuffed in them (2.8 liters w/ .7 cm tall, uFonken style slot ports).

I've input specs into a few different online calculators and get suggestions that vary quite a bit, from 4.2 to 3.64 liters (I figure your uFonken is 2.38?) -- but a bigger variable in port suggestions...
