Im gonna guess 224ci is cubic inches? How about you convert that to ft^3 then tell everyone what you want it to be tuned to so you can get some help with it...

24 square inches per driver for a slot port. That's a rough figure to use. Box size and tunning will effect what is required.

sorry I screwed up my math and forgot to include width in cubic inch calcualtion. Its 7152ci, or 4.14 cubic feet
