Aero Port guide?

[7ender 10+ year member]

Is there a guide or 101 type thing for how to make aeroport boxes? iv'e been searching around and get the basic idea, but I have alot of questions about them and I was just wondering if there's one place I can read all about them on.

Iv'e already checked out psp-inc, and I know how long my ports should be. I want to know what the differences are between choosing something like 4 4" ports vs. 1 6".

If there's nothing around, i'll just keep searchin around here, but I was hoping there might be somewhere I could just read up all about htem at once.

Thanks!

A lot of people, including me, go by rules of thumb with aeroports. The best feature about them is that they're very easy to quickly re-tune, allowing you to easily tune them to what you like.

And they don't take up any room like a slot would.

That's 90% of the reason I use them.

And of course too me they are always louder, but that's arguable I guess

Thanks!

Required port area, length and "chuffing".

Well, I'm trying to make a 4.0ft^3 @32hz box for a 15" Lethal Injection.

If someone could help me design one would that would be awesome =). I know the basic dimensions I need, but I'm not sure how to incorporate the aero ports.

From my searching around, iv'e decided that i'm going to use PVC pipe, and use a heat gun/bowl to flare the ends.

How do I determine if I should use one 6" port or multiple 4" ports? Both come up with reasonable lengths when plugged into psp-inc. Is there some general rule that bigger diameter ports are better, etc?

Thanks for all the help!

Once again, most of us go by rules of thumb. Fit the most port area and port length that you can. Use the port calculators and start off with a high amount of port area, and if the port length is unreasonably long then cut down on port area.

I'd try to do 3 4" (might be tough to fit) or a single 6" (should be easy to fit). That low, 32 hz tuning makes it a little harder to run a lot of port area without the port length becoming stupid long.

Alright thanks.

So what exactly would be the difference between the 3 4"s and the 1 6"?

The calculator says I'll need 22" or port if I use the 4" pvc, or 16" if I use the 6".

Which would be a better choice? I can fit either in my box.

3 4" is a tad bit more port area. Which is the better choice probably depends on the box design.

1 6" aero is only about 28 square inches of port... Is that enough for a single 15"?

Yes it is. I have a 6" aero in 4 cubes with my 15 and its the loudest box so far in the 2 years I've had the sub.

You can get away with it. One of my teammates is running 2 6" aero's for his 2 15's and is near a 152 at the headrest.

Well said.

For a daily setup just do one 6" port. It'll be easier and cheaper.
