Bigg Boy Posted April 29, 2009 Report Share Posted April 29, 2009 I need some help. I have done tons of box design. But I never really design boxes that use aero ports. Im designing a box for 4 12"s that is 9.3 cubes. I was thinking 4 6", which is 113sq inches of port which is what I am guessing is about right. I know you dont have to use as much port area when using flared ports, instead of normal ports. Is that the proper amount of port area? Here is my real problem. To tune to my daily freq (33hz) they ports would be over 17" long, which is as long as they make it. How guess have any suggestions? this would be alot easier then doing a interchangeable slot port. But I cant get the numbers to work.

Airborne Posted April 29, 2009 Report Share Posted April 29, 2009 go buy some pvc at lowes and make it longer. They have the same type. I forget the name of it but it is black and comes in short lengths. Quote Link to comment Share on other sites More sharing options...
bkolfo4 Posted April 29, 2009 Report Share Posted April 29, 2009 You don't need that much area with aeros. . .(3) 6" would be fine for (4) 12's That is still over 20 sqin of port per 12 and should cut the length down to 17" long.

It will be the best $130 that you've spent on the box. I think that it's a great idea to run 4 and plug one of them for daily. I have 6 4" aeros right now for my 2 15's, but I have 2 more waiting to be put into a new box. That will be 8 4" aeros and probably 2 or even 3 will be plugged for daily. You won't regret the aeros, that's all I will ever use again in my boxes unless I do a wall.

BJD3 Posted April 30, 2009 Report Share Posted April 30, 2009 Slightly off topic. I know for slot ported boxes, it is ~16 sq. in. of port per cu. ft. Is there a rule like that for aero ports?
