Aeroport general rules to follow?


Recommended Posts

how big of an aero port for:

2 10s

2 12s

1 15

etc

so what kinda port area pretty much should i be looking at?

and what kinda in sq per cube?

where to buy? cheapest? good places to buy with good product.

PVC ok? is flaring required( i saw vids on how to flare PVC) is it necessary.

any other general rules for a guy with no experience with aeroports.

i have built plenty of slot port boxes, im looking to save space and be louder with aero ports!!

thanks guys

9-13 cuft per ft is a rule but doesn't alway need applying,

Also diameter of port = min. distance from wall/ restrictions apron exit and entry of port

Flared assists to minimise port noise and incress efficiency, but not required

There is no ratio/size of port to size of subs

Every sub is different and in different boxes,

the xmas combined with cone area has more to do with it the the size of sub

1 larger port is better then several small ports but 1 large may not alway fit

These are the minimum number of ports per driver. Multiply the ports by the number of drivers you have.

15's need 2 four inch ports.

12's need 1 four inch port.

10's need 1 three inch port.

now that's a load of crap, how can you say that as a generic scale,

port size has and will always be determined by sub, box and configuration

2x4" is optimum in 2-2.8cuft net

1x4" is optimum in 1-1.4cuft net (how many 12" subs do you no that like this amount of cuft, unless overdrive at full tilt, yes there are some but not many, its more likely to be a 10")

1x3" is optimum in 0.5-0.8cuft ft net

Well since you will be using a calculator anyway give a port area of about 9-13 square inches per cube, keep a clearance in both ends of about the diameter of the port if you want to get the calculated tuning. Those are a couple of rules that you can rely on.

Also you may want to know that big boxes require short ports and small boxes long ports, high tuning need small ports low tuning requre long ports, so if you want low tuning and/or small subs it will be uncomfortable. Running the aero partially/totally external or bending is one way out of a tight situation.

Of course use flared when possible, sometimes the flare is so big that you will run into trouble fitting it in the face of a box specially if you are placing more than one.

thanks guys. if it helps ill be running DD 9500 series 10s or 12s so ill prolly be going big on box size and big on port area. so flared is necessary then?

What is a good aeroport for 2 zvx18s with 11.5 cf 

Squeeze another .5 cubic foot net to equal 12 cubic foot net and do 8” aero ports (3) from big ass ports. Don’t worry about going against recommended specs, it’s not out of the norm to do this and companies use recommended specs as a guideline and they know and we know things vary on each application. The max length per port they sell is 22”. So on 3 of them ports, that would be 35hz tuning on 12 cubic foot net and about 12.285 square inches of port per cubic foot. Which is nice on an aero port build. Now let me figure the displacements of ports and subwoofer and I’m gonna add 0.7 cubic foot displacement for bracing. Subwoofers are about .23 cubic foot per subwoofer. And each port has a displacement of about 0.705 cubic foot. So to yield 12 cubic foot net volume, you have to add these figures to that net volume so you know the gross volume of the actual enclosure you are trying to get as close as possible to when typing in measurements. 15.275 cubic foot gross volume is what’s needed.

@1point21gigawattsHey I was looking for some help I’ve read so much and I just get more confused each time 😂. I have 2 15” kicker solo barics in a 10 cubic ft sealed box shared chamber. The sub specs. Fs(25.48hz) Qtp(0.718) Qms(15.3538) Qes(0.5856) Qts(0.5642) for rest of the specs they’re here https://www.kicker.com/app/tsparam/44L7S154.html 

I want to make my sealed box ported with an aero port but I have no idea what length or diameter port to get I’ve tried the calculators but I just don’t get it I get negative numbers and weird numbers that’s don’t make sense. If I could get the port diameter and length I need I will make one from pvc. Thank you sm for the help in advance.

Go with 2 big ass ports 8 inches stock length.
