hey there everyone.

i'm going from 2 xxx 15's sealed to 2 xxx 12's ported, when i get them back from David, for motor repair.

how many inches of port do 2 05 xxx like. never done 2 ported, only one ported.

Before everyone gets on my *** about searching, i have, and most of them are about one sub, not two.

i know one likes around 30-35 sq/in port.
would 60 sq/in port be too much for two of them?

box is probably going to be 4 cubes @ 30hz

thanks

John

Rule of thumb is usually 12-16 in^2 of port per cubic foot

Listen to this guy.

Port size is basted off box size and not sub size. Good rule of thumb is 15-17 Sq.In. of port per cu.ft.

I was thinking about 55 sq/in port, i just don't want any port noise, if i have to little.
