Aero ports

Silver Member Username: Terry6405Sullivan, IN US Post Number: 599 Registered: Sep-05 | point me in the direcion of the cheapes aero ports out there, i am looking to externally port my SX 15 to give it more room and make it louder i have it in a 3.6 cu ft box tuned to 32hz and its loud and hit low, but i want it a little louder, i think ill have to go with areo ports because my box is the absolute biggest i can fit in my trunk without building it in the trunk, soi think i will duplicate my box size, but without a port, then stick some areoports on it what tuneing shoud i go for, and what size ports? |

Silver Member Username: Terry6405Sullivan, IN US Post Number: 605 Registered: Sep-05 | yea but how do i know how many i need and what length? im used to sloted ports and never messed with pvc b4 and do they all have to be the same length? or can i chang the lengths of ane or to to change tuning? |
|
Silver Member Username: JbumpNebraska City, Nebraska USA Post Number: 213 Registered: Dec-05 | I can change the lengths with mine.. you can see the joint in my pic.. they're tuned at 35hz, but for SPL, i could tune them higher if i want too.. |

Silver Member Username: Safe_crackerChicago, IL US Post Number: 666 Registered: Jan-06 | Well My box is 4.47cf, with four 4" aeros and each has a length of 18.5" including both flare ends. Do not mix lengths you will get very poor results. My box is tuned to around 40hz but in vehicle it comes out to around 36-38hz, dependant on conditions. If you are short on space you will not get this box or your either with external aeros, takes up a lot of room. I really don' think anyone in IN can handle this box anyways, lol. Polo..   |

Silver Member Username: Terry6405Sullivan, IN US Post Number: 606 Registered: Sep-05 | yea because indiana is really far from chicago, so the people must be compleatly different but anyway, i want a box very similar to yours, but i want the sub in normal, but how is the SQ at that tuning? and is it safe to run it at that daily? o got a nine.1 btw |

Silver Member Username: Terry6405Sullivan, IN US Post Number: 607 Registered: Sep-05 | dont you need more port area that those 4 - 4" port? and what do you mean by tuned to 40, but 36-38 in a car? and where did you get them? |

Silver Member Username: Jprix82Post Number: 481 Registered: Jan-06 | Hey Jay B. how did you make them |
|
Silver Member Username: JbumpNebraska City, Nebraska USA Post Number: 215 Registered: Dec-05 | i used a torch to heat them up and flare them on a bowl.. some people use a heat gun, less worries about burning the PVC.. took my a couple test runs to figure out how to heat them up without burning them, but it works... then just flange them on a flat surface.. i used my work bench.. takes a wile to let them cool so they hold their shape.. poor cold water down the PVC to cool it so it'll stiffen, then i used a router bit to counter sink the screws... |

Silver Member Username: Terry6405Sullivan, IN US Post Number: 608 Registered: Sep-05 | hmm..... thats genius and i could use 6" PVC from lowes. do they have 8 10" PVC there? or anywhere? |
|
Silver Member Username: Terry6405Sullivan, IN US Post Number: 609 Registered: Sep-05 | 8" or 10" |
|
Silver Member Username: Safe_crackerChicago, IL US Post Number: 674 Registered: Jan-06 | Do you really know how long the ports would have to be to run those large dia ports? Four 4" port are quite extreme area wise, a program will tell you one or two for it to tune right. When I say in car tuning I mean when played in the vehicle after the sound has been beatin up by your cars interior it will tune a little lower than the port tuning itself. This box can play from 20hz to 80hz, running extremely strong closer to the middle. Round ports are able to play more frequencies due to a less sharp cutoff unlike slot-ported enclosures. The smaller the box you use the higher the tuning and longer ports you will have to have. Polo..  |

Silver Member Username: Jprix82Post Number: 482 Registered: Jan-06 | Jay B y ou got any pics of when you was making them? |
|
Silver Member Username: Terry6405Sullivan, IN US Post Number: 610 Registered: Sep-05 | can use pvc elblows so i can hace longer ports? |
|
Silver Member Username: Terry6405Sullivan, IN US Post Number: 611 Registered: Sep-05 | do you screw the port on the inside or outside of the box? |
|
Silver Member Username: Terry6405Sullivan, IN US Post Number: 612 Registered: Sep-05 | polo: according to this site, your box is tuned to about 37-38hz http://www.carstereo.com/help/Articles.cfm?id=31 |

Silver Member Username: Safe_crackerChicago, IL US Post Number: 678 Registered: Jan-06 | Funny you can get different answers from different sites. You screw them on the inside of the box and put them together outside, use electrical tape to hold them together. You must seal the inside flare with a sealant to maximize efficiency. With Aeros I would not try to use an elbow because you would be defeating the purpose of an aero which is to minimize port noise by adding a restriction in turn will be noisy. You may be better off with a different box like this one but with one sub? |

Silver Member Username: Terry6405Sullivan, IN US Post Number: 614 Registered: Sep-05 | that is exactly what i was thinking, its gonna be 31"W x 30"H x 14" tall it sould be over 5 cu ft after all displacements still not sure what i want to tune it to - i was thinking about 37hz but i donno yet and i think ill have the ports goin into the cab of my car so it'll be really windy in there, i love that it will suck to get it in though, ill have to go through the backseat door or whatever you call it, and i might evern have to take out my seats to get it in it sould be really loud like that thou, i hope anyway, it will basically be a TCAB box, unless they do something that i just dont know about. and i think i just get 4 of the aero port kits listed above--4". im pretty excited about building it it should be a hell of an improvement from the 3.6 cu ft net slot port box i have now, not nessicarilly in SQ, but almost deffinately in SPL im not sure how the sub facing up in a trunk will be though tell me what you think, ill probly post my plans later |

Silver Member Username: Safe_crackerChicago, IL US Post Number: 686 Registered: Jan-06 | Hard to tell maybe post pics of the trunk interior space and maybe a picture of what it looks like behind the back seat. Polo.. |
|
Silver Member Username: Terry6405Sullivan, IN US Post Number: 615 Registered: Sep-05 |   these are pics i had that box is 31" wide x 16.5" tall x 23" deep you can sorta see the box behind my old amp im almost positve i can fit the box i said b4, but the total net volume will only be like 4.6 cu ft instaed of 5 does that sound like it will work to you thou? i really think it will another plus about facing the ports in is that the air will keep the amps cooler because it will be blowing directly on them with the back seat up, so it make sense to me |
|
Silver Member Username: Safe_crackerChicago, IL US Post Number: 688 Registered: Jan-06 | Ya, the sub will face your back seat and the ports will come out of the side and they will point to one of those corner poskets you have in the rear of your trunk. The ports go on after the box is in. Polo. |

Silver Member Username: Terry6405Sullivan, IN US Post Number: 616 Registered: Sep-05 | actually i was planning on having the ports inside the box because there is only 10-12 inches on the sides where hose pockets are. i think that way i can maximise cubic footage and have it tuned pretty low. and i was also planning on having the sub on top the box i was planning is exactly like the TCAB one you posted, with the sub on top, and the ports blowing at my backseat, or into the cab of my car when the seat is down. i figured that way would be cleaner looking and a little easier would it be better to port them externally? even if i lost some net cubic footage? and what do you think about the sub being on the top of the box, facing up? |
