Question about sub box space

So i have 2 kenwood kfc xw100’s which have recommended air space of .65 each. The maximum volume for a sealed box is 1.0 cu ft according to crutchfield. The (sealed) box I ordered gives each sub .95 cubic feet of space and i’m wondering if that’s gonna be okay or if i need to get another box/ modify this one. I know it’s within the range but just don’t want to damage my subs or anything. Thanks in advance I’ll answer any questions needed
