Aero port area issues

[robertdbardos]

I am working on designing a new box for my 2 sa 12's my idea is a trunk wall subs and port facing in the cabin. I am aiming for 4.28 cubes 31.5 hz and close to 55 cubic inches of port. My maximum dimensions for my box width 30 depth 25 height 15 my issue is finding the correct size aero port to use to achieve tuning and port area. I have used a few calculators but each one comes up with a different outcome. The sa will be ran on a sundown saz 3500 any suggestions will be much appreciated!

you could go 1 8" at about 26" (50" ^2)

or you could go 2 6" both @ 29" (56" ^2)

Ive got 2 dc xl12's on a saz 3500 and (1) 6" aero and its sooo loud and low its amazing BUT, I've got a ton of port noise at low volumes. I would recommend 2 6" aeros but they're gonna have to be pretty long

I think I'm going to go with a slot port i found a box that fits perfectly and with the exact requirements i need
