Best air space for sealed 12" Qs

[Proximity 0]

I'm sure this has come up before, but I searched and didn't find anything. I'm designing my box to have 1.3cuft per speaker. What would change if I moved it up to 1.4 or 1.5? would it make much of a difference?

Also while I'm here, for the BP power, the website says it "increase power handling from 200-500 Watts depending on the application. 
". In this application, being 1.3cuft sealed, would I be okay giving them 1300w?

Thanks for any help.

Mine is 1.4 before displacement with a Crossfire Vr 1000d and it is amazing.

I'm at around 1.3, using an alpine 1000.1 which is probably more than 1000 watts, and it sounds great. I'm going 2.2 ported though, screw sealed.
