[QUOTE="SQBubble, post: 2791490, member: 566772"] that kind of box would be tuned around 32hz... 37.5 sqinch of port area is for 12inches subs... usually a 15" take around 40 to 70sq.inch and an 18" should need from 70 to 130sq.inch it really depends on the amount of air that a sub can produce and the size of the box ppl say each cubic feet need 16sq.inch (quote from digital design) but it varies [/QUOTE]
