    also, JL lists the space requirements at 1.125 cubic feet when tuned to 30Hz

    look in the build section to get some ideas of how it goes. maybe just use the re calculator. http://reaudio.com/speaker_box/LPort_Box_Calc.html

    Re: slot port build

    ok, how important is it to keep within the space requirements and tuning specified by JL? i cant seem to get a combination of LxWxH that works to get the space right and also allows me to tune it to 30Hz as JL suggests without going to a .5 inch port width....
