Aeroport Questions

[ascitiesburn69 10+ year member]

Ok guys i plan to get a hdc3 12" and an AQ 1200d to push it. Box is planned to be ~2.4cuft after displacement @38hz. I planned to use aeroports to be able to keep the box a tad smaller. Is it better to use more than one aeroport in this situation? I plan to use one 4" aeroport @5.6" however that is the calculation for a round port without the flares. So what would the length need to be for an aeroport including the flares if i used a 4" diameter one. and could someone explain how to figure this out? And also what the length would have to be with 2 aeroports? And also Whats the best place to put them IE: on one side of the box on top of one another, side by side, one on one side of sub etc..

Thanks alot

Use the second calculator on the link I have below. Whatever you come up with, add an inch to the overall length of the port if you are using Precision Port aeroports. Let me know if that makes sense

Ok so if im using 2 4" aeroports in a 2.6cuft box with a desired tuning of 38 it requires 15.11 port length so with aeroports it should be 16.11 so with 2 4" each "aeroport" each one would be ~8.05" ?
