Must me made perfectly Not very useful for daily systems, they usually have extreme peaks Bigger box than ported/sealed systems (usually) They take a lot of trial and error Sometimes makes subs pop from over-excursion (rare, but more common than other boxes) Id rather see you build a 6th order than keep working with the stupid dome... With 4 15s (or 12s, i forget what your running) the box might be as big as the wall tho haha. |

Gold Member Username: JakeyplaysbassSt. Louis, MO / ASU Post Number: 3659 Registered: Jul-05 | To get you started... When building a 6th order bandpass box (quasi-sixth is another name for it) you look at it as 2 different boxes with 2 different tuning freqs. I would start by tuning the interior port (the one closest to the sub) low at around 30-35hz and then tuning the exterior port higher at around 80hz(some say higher) to start with. Test it on a mic and then make adjustments to both ports until it hits a peak SPL. Usually the interior port will be tuned anywhere from 5-20hz different from the exterior port depending on the vehicle, subs, ext... There was a few guys on the termpro forum that knew alot about bandpass boxes when i was messing around with them a few years back. Maybe search there. |

Gold Member Username: JakeyplaysbassSt. Louis, MO / ASU Post Number: 3660 Registered: Jul-05 | I dont remember the exact scores but i know we broke 150 with 4 10s. Im pretty sure the amp was a crossfire vr2000 but i have no clue what ohm we were running at. It was awhile ago. |

Gold Member Username: SouthernrebelMonroe, Louisiana Team Audible... Post Number: 7535 Registered: Mar-04 | 4th and 6th order boxes can be very nice for daily drivers also. I did a DD1508 in a 6th order awhile back and did 140 @ 45hz w/ it and it played everything. Also, I am doing a 6th order in my avalanche w/ 2 DD3515's. I have done the DD2512 in a 4th order and it sounds great. Amazing extension and quick punchy bass. Some subs are mean in 6th orders but suck in 4th order. Its tricky. |

Gold Member Username: DeadrabitMarionville, MO Post Number: 1996 Registered: Jun-07 | i don't see how they can be good for daily. i thought they would have a higher peak, just loud with a few notes and suck on everything else how do you change them for daily? |

Bronze Member Username: Cdb004I got 6 12s 153.1 daily Post Number: 90 Registered: Oct-08 | You get two peaks and you can design them to work either way. A good bandpass box and sub will have more range too. |

Platinum Member Username: InsearchofbassYork, Pennsylvania Post Number: 11841 Registered: Jun-04 | http://colomar.com/Shavano/4thorder_info.html Is it me or does the ported side generally get to be twice the size of the sealed side. Also how would I design a box for 8 12's in a compound isobaric design? |

Bronze Member Username: DangerangerOhio United States Post Number: 98 Registered: Mar-09 | Can both sides of a bandpass box be ported? |
|
Platinum Member Username: InsearchofbassYork, Pennsylvania Post Number: 11854 Registered: Jun-04 | Thats what a sixth order bandpass is. |

Bronze Member Username: DangerangerOhio United States Post Number: 100 Registered: Mar-09 | okay thank you. Are you suppose to tune to the same hz? For a good daily setup? |
|
Gold Member Username: DeadrabitMarionville, MO Post Number: 2014 Registered: Jun-07 | u tune them different. one low and one high, never made one so im still not to sure about everything u can or can not do |
|
Silver Member Username: DangerangerOhio United States Post Number: 101 Registered: Mar-09 | alright well I'm going to give one a shot too. Thinking one side 33 hz one side 45 or are they both still too low? |
|
Gold Member Username: DeadrabitMarionville, MO Post Number: 2015 Registered: Jun-07 | i talked to a guy today about it. i think he said the closer togather theyare the more notes they will play. and farther the difference the more of a peak you would get. but idk i might have that mixed up |
