IM building a ported box for a rf hx2 punch 15" sub pushed by a jbl 600.1 ... the box is gonna be 3.83 cu. ft. and wanna tune it to 40 hz (which is also open to suggestions cause im looking for spl) thanks... im too much of an idiot to use WinISD!!!

o yea.. the xmax for that sub is 14mm... (.55 in.) if that matters
