That info goes together with the line above it on the website, which is that you need an enclosure with 6.25 cubic feet of internal volume, after accounting for the driver and vent (and the bracing which a cabinet that size should have) etc.
You then install (or more likely build) a vent that has a cross sectional area of 70 square inches, which is 22 inches long. (If using round pipe for the vent, it needs to be 9.5" internal diameter to achieve that, which may not be a standard size, hence you end up building the vent yourself.) That should result in the box having a tuning of 35Hz, which is what the maker thinks suits that driver. Regards, David.
