Box size question.


I wasn't going to build anything quite yet but the call of the drivers is becoming overwhemling! So what I plan on doing is just building some test boxs till I build the art deco ones that will take all winter long, anyway, what I don't get is what box size I should be using for the 2226's. PiAlign says to use a 2.5 cu ft box amd I've seen boxes of various sizes used. If someone could enlighten me I would appreciate it.
