sub box help

[c0la 10+ year member]

I have measurements that i have come up with and just wandering if someone would be able to check over them?

Internal dimensions are 34.5L x 14H x 25.75L = 7.2 cu. ft.

Port measurement 14H x 5.25W x 14L port displacement? .77 cu.ft

The actual specs call for a 12.5L port but thats tuned to 42 and i want to drop it down to 35 htz, dont know if that will work or not

actual volume=6.43 cu. ft.

I just need to know if i'm wrong with any of this? any help is appreciated

thanks

Sorry for the confusion, this isnt for my subs. i already have a box just like supaC for my 15's that slam hard as hell.. this is for a friends 15's she just picked up and the enclosure space is what is needed with sub displacement.

ma audio 1550w series, i already have them in a crappy old sealed box i made out of an entertainment stand 5 yrs ago, which is just particle board and they actually have good solid bass for being that box. she wanted them in her car and i said here's this for temporary use til i can build a box around the subs.
