.7 sealed, 1.18 ported. Port 36 square inches by 26.25 inches long. That's for one, and straight from DD. I spoke to a guy at a comp that is doing 157's with (8) 2510's in a 4th order and he said those specs were pretty close to what he did the first time, but if he did it again, he would go a little smaller sealed and little bigger ported. Like .5 sealed and 1.5 ported.
Good luck and let me know how it turns out. I am building one for my 2510 tomorrow and I'll be doing .5/1.5.
