WOLFRAM FTW
i've check that box it looks ok just remember u have to subtract sub displacement so u would have 1.85cf ad in that box.. if u want 2.8 cf they do have a 3cf box.. if u can find someone close by to make one someone here can do box design for u..This is the box I plan to purchase on eBay:
12-Inch CUSTOM-PORTED MDF CAR STEREO SUB WOOFER ENCLOSURE 2 CU. FT. TUNED @ 32Hz | eBay
Im leaning towards a GCON sub instead.. Ideally want an enclosure thats 2.8 cu.ft tuned @ 30 hz , if I can find a box builder local that can build a similar quality box for me for around $150 mb I'll go that route
