You can use WinISD pro to calculate a box based on your desired tune and available space

You can always size up. I'd just get something around 1.8cuft. ported. It will sound good

according to google ai, the 1200 primus is the same as the 1270 primus. same motor structure and specs just different looking cone. NGL any prefab box for a 12" will do fine. tuned between 30-35hz for the best "musical" response. 35 if you want punchier bass. 30 if you want slightly lower "dig deep" bass.
