Aero port ?

[1ndatrunk 10+ year member]

I was trying to determine how long I needed to cut my aeros to achieve a certain tuning. On the calculator if it says 7" long for 1 aero and 15" for 2 aeros is that 15 per aero or is it 15 and then cut it in half to make two?

If you double your port area ie 2 ports than it will need to be longer. tuning for 1 port will be shorter.

So each port would be 15" and be the equal tuning to the one being 7"?

Thanks, thats what I needed to know. Now in what ways wre multiple aeros better than single? Does it make the sub louder due to the increased air flow or is it strictly for port noise issues?

you need a certain port area. determined by box volume. i think the rule is 12 sq. inches per cube. that doesn't mean that breaking the rule will, for sure be worse. it's just a general rule. in 2 cubes, i would always do 2 4 inch aero's, or a single 6 inch.

Thanks, but does it affect the loudness? Never used aeros so I'm trying to learn

12-16 square inches per cubic foot is for square ports. aero ports only need about half that (what ive read atleast)

yes. it will affect output. in the right box, aero's are fine. if they too long and i have to bend a round port, i switch to a slot port.

actual aero's, with flared ends. with just a piece of pvc, i still stick with 12. my 2 cents.
