You dont need the t/s specs to design a good box. The ts specs are actually going to vary from sub to sub based on break in anyway. m2 XL 12s on a 5k, I would go with 1.5-1.75 net per sub with 14-16in2 of port per 1ft3 and tune based on the type of music that you listen to. If you listen to alot of rap, tuning in the low 30s would be good. If you want something that will sound good on most rap but still play rock and country well, then a 35-38hz tuning would be good.
