I have 2 Alpine Type R's [SWR-1243D]

Okay i found someone to custom make me a Ported box for these subs and these are the specs he recomended/ And i agreed. Before i give him the "Go" to start working on it i want to get other peoples opinions/sugestions and or comments.

*Chambers: 2 Each subwoofer with its own chamber
*Cu Ft per chamber: 2 cu ft
*Tuned from anywhere from 30Hz-35Hz (Please give a suggestion...Im thinking of 32Hz)
*3/4" MDF

Now i am stuck on which design i want to go with...
The 2 ports/Vent side by side in the middle such as...

The ports/vents on the sides of the subwoofers such as...

Thank you
