Sorry I have not been on the site until now. Optimal size for a pair of 18's ported would be in the 12.5 - 15 cube rage. Port area, just stick with the 14-16's per cube rule of thumb, so for a 12.5 cube box aim for 175^2 to 200^2 inches. :)

I am going to say they will work great in 6-10 ft^3 each. 80-100 sqin of port per sub is enough.

Yes, they can be reconed.
