ok tommy from team kicker said 4.5net after sub and port displacement

so this is what i came up with for the dimensions

the sub displacement is .27 per sub correct

and the port displacement will be .30 each port bc 6" port which is going to be 28.27 and multiply it by the length of the port(18.14--33hz tune). then you divide by 1728

which would be .30 so for subs and ports the total displacement would be

1.13cuft

so these are the dimensions i came up with for a box to have 4.5net

tall 28/26.5

width 17/15.5

lenght 26/24.5

should be 5.8 before displacement and then total displacement should be around 1.15 which leaves 4.6 left which would equal 2.3 net for each sub

could someone check to see if all thats right and if not let me kno whats wrong

You may want to double check port length since you are making the box smaller. I didnt check the exact math but the way you are going about it is correct.

well the port lenght would need to be 18.14 each and my box is 24.5 internal on the length and thats the way the ports would be put in so there would be over 6 inches from end of port to the wall is that enough

I just meant port tuning changes with the size of the box. I wasnt concerned about there not being enough room inside the box.

yes i see your point exactly the ne volume changes the lenght of the port and at 5net is calls for 24 inch long ports if i do 2 6inch diamter ports and that wont work bc my internal where the port will be is 23.5

so my question is to keep my 33hz tune at 5cuft net what should i make the aeroports have 4 4inches or what

one more question when it says 24.5 flared port length when i pick 2 aeroports at a 6inch diameter is that with both combined or each one has to be 24.5

 

[mokedaddy 5,000+ posts]

Thats a tough one but yes you most likely will be able to get away with 4 four inchers. Or you could maybe even do just three. The best way is to test but four 4" sounds like a good place to start.

Each port must be that length.

The length is for each aero port.

ok i cant do 4 4inchers bc it comes out to be 22.95 and thats too big i can do either 3 or 2 4 inchers

also how do you figure out the airspace that 4inch aeroports take up (whats the area of a 4inch port i kno how to do the rest of the math
