Hi
No problem. For a sealed box, there is less of an ideal size than with vented, however in your prediction, you can see the larger volume gives a response shape with a lower "Q". Generally speaking a Q of .7 to around .6 is ideal and the red curve would be the lower Q of them.
IF one made the box much smaller, you would see the Q rise and that would accompany a bump at the bottom end.
Off hand, any of those curves would be good and not exaggerating anything.

I would add loosely fill the back with cotton padding or fiberglass if sealed

IF you use these with a subwoofer later on, the sealed box is the way to go.
