problem is, that sub is an SPL driver. it will be pretty difficult to get good SQ. check out the size of that surround and how little cone area there is. it is going to move alot of air through excursion but be very sloppy. id say port it to like 38-40 Hz. i have not hear this sub ported before but i know that sealed it doesnt sound very good. loud as hell but not very responsive.
