    the port part of your measurements confuse me. i see the 11.76in per cube, and i wonder how you got that? 180sqinch^3 / 18.63 is 9.66 per cube. But doing 180 / 15.3 is 11.76. I thought that you figure this by the total gross volume of the enclosure. it again i have been confused by this for a while but didnt understand which way was correct.

    Re: level 5 18s box help

    I used a box tune calculator to get those numbers.i just kept playing with the deminsions to get the hertz around 30-32 and the inches^2. Of the port Around 180- 200.
