I have about 2.66 cuft net tuned to 40hz. That includes .17 cuft displacement for the sub.

The recommended sundown airspace is 3.0-4.0 net after displacements. I've built smaller than manufacturer recommended specs and have been perfectly fine. But, if you are able to go bigger, I certainly would.
