aeroports vs slot port

[Lakota 5,000+ posts]

ok so with 2 12's l7's in a box with the specs of 26long 35 deep and 17.5wide and i would like it to be tuned at 33hz what ports should i put in it and after port and sub displacement what would each sub have in airspace

Subtract 1.5" from each side and then multiply those dimensions. After that divide by 1728 and you will find the internal volume of the box in cubic feet. Sub displacement is listed on Kickers site. Use the port calculator on http://www.psp-inc.com to figure out tuning. If you're going to do internal ports don't forget to subtract the volume of the ports from the volume of the box.

ok well viveet told me that aeroports cause port noise and slot ports seem to be a better way to port subs whats your oppion on that

and also in 2 ports that are 6 inches in diamter and around 19-20inches long will that work for a box that is only 26inches long

and also for those ports how much airspace would they take up

if somone doesnt mind i was wondeing if they could give me the dimensions for a box for 2 12's l7's after aeroport and speaker displacment so each sub has 3-3.25cuft

thanks

I think everyone has given up on you. Figure out what you want and then someone might help you.

Aero ports are more expensive and take up less airspace.

Slot ports aren't as expensive and take up more airspace.

nobody wants to answer his dumbass because he bumps his own thread every 10 mins.

do you duct tape the joints on the ports so you dont have to glue them, making it easier to tune?

sorry for me being such a DUMBASS for asking ????'s to learn new things and maybe no longer be a dumbass bc i am pretty sure either you asked questions you didnt kno or someone sat down with you and told you everything about audio we all start off knowing nothing so you were once a dumbass yourself

i am just wondering how much airspace would the aeroports take up if they are 2 of them that are 6inch in diameter and 19-20inches long

and also is a aeroport or a slot port louder

and which one has the most port noise

can any of you none dumbasses answer those questions for me

thanks

try searching then.

when i dont know something i search...and guess what? i usually find it when its a topic thats been discussed a thousand times.

i was going to answer some questions yesterday night, until i saw that you bumped your own thread after 10 mins...

you dont worry about the flares since they wont make much difference. you get the area of the 6" port which is going to be 28.27 and multiply it by the length of the port. then you divide by 1728

ok sorry for posting so much

but can i get one more answer from a box builder

i want to try nd build my own box aeroport box for 2 12's l7

i would like them to have anywhere from 3-3.25cuft per sub after displacement for everything and the tune to be 33hz

and this is the aeroports i guess would work best for my box it said on psp-inc.com

i figured to go with 2 6" flared ports that are 18.14 or straight port at 17.14 which ever is best i heard flared was best

and my biggest box i can go with is 26long 17.5 wide and 35deep so what should the box dimensions be to give each sub 3-3.25cuft after displacement of everything

and also would the 2 6" flared ports that are 18.14inches long come out to being tuned at 33hz

sorry once again

you gotta clarify your dimensions.

how tall can the box be?

how wide from left to right?

and how deep from front to back?

as it stands, your dimensions are a little hard to understand. you mean 17.5" tall? etc

sorry for not descbribing them better the subs would be facing up towards the roof in my truck so 35deep would be from top to bottom and wide 17.5 would be the width of the box as in right side nd left side and the length would be the lenght of the box from the back wall to the front console which is 26inches

this drawing i made is a top view hope you understand what i am trying to explain

hmm, still dont understand whether this is going to be in the back of the truck or betweent he center console somehow. kinda confusing.

well, either way, to design the box i can only use 2 dimensions, leaving the last one as a variable. so you gotta tell me, which two dimensions are the most important to you.

do you understand the dimensions now

 

[king ranch 5,000+ posts]

ok it will be in a truck inbetween the rear bucket seats and inbetween the back wall and the front console so the

the wide is the distance between the seats that needs to be only 17.5max the lenght is the distance from the back wall to the front console max of 26inches and the depth would be from the very top of the box by the roof to the bottom of the box and i was planning on mounting the subs on the top of the box by the roof

i hope that helped

and the length and width has to be that size and the depth can be w/e as long as after subs and port displacement each sub has a net cuft of 3-3.25

do you understand what i mean now
