i have 18 cu to work with after displacements, and im wondering if that is enough air space for 4 bl 18s or do i need to step down do the bl 15s?

Step it down to the 15's!

what would you use for the MIN on the 18s ???.....

Fi recommends 5-8 cubic feet for the BL 18's

I'd suggest going to 15's as well.
