Do the 12-16 in^2 port area apply to aeroports?

[ghart999 10+ year member]

The general rule of thumb for port area to avoid port noise is 12-16 in^2 per cubic foot of volume. Does that still apply to aero ports?

I want to go 3 ft^3 tuned to 32Hz for 2 rl-P 12's using a single 6" aeroport (28.25 in^2 of port area).

This seems too small to me to work to avoid port noise.

Thanks all.

I was actually wondering the same thing

bahhh. i dont think that goes for earo port because of the way the port are designed to resonate port noice

What the hell are you talking about?

No, it is no imperative that you have 12-16 sq in of port per cube when using aero's.

well to put it inter perspective.... one of steve meades first box for the tahoe only had 4 6" aeroports for 4 18's,

i think it actually works out to about 60-70% of what you would "normally need"

i do know that its better to go bigger than multiple smaller, the less surface area the better...

for instance 2 4" ports have approx 25in^2 and a 6" port has approx 28in^, not a big diff, but would be better to run the single 6" than the 2 4" because of surface area

Just curious, but surface area of what? Do you mean displacement?

Internal surface area of the port. Everything he said is basically correct.

Cool & thanks man
