Post Number: 3993 Registered: Mar-04 | Well, i have been thinking about it and studyin up for awhile i have finally talked myself into it. I'm gonna build a 6th order series tuned bandpass box for my 9515d tomorrow. I already have everything sitting in my shed...screws, glue, 1 and a half sheet of mdf. Here is the kicker though...i'm gonna build this lil fella w/ interchangable ports and removable panels. Should be interesting. I have 5-6 designs drawn up so far...slimmed it down to 2 though. Cant deside if i am gonna fire the port up or to the passenger-side wall. Either way...i'm gonna start out w/ the rear chamber tuned in the mid-30hz range w/ ~40sq in port and the front tuned in the mid-60hz range w/ ~60sq in port. Also, the internal baffle will be 1.5" thick. Pics will come when (or if) i can get em up...i'm at my dads house and they have dialup...connects at 26.4Kbps  May the box-building gods be w/ me...i'm gonna need it. lol |

BTW, about the 8inch subs and box you are gonna sell me, when will you have it ready? I didn't get enough money for Christmas, but if you will let me know ahead of time, I can save up the money. |

Post Number: 3994 Registered: Mar-04 | ok...i didnt get a chance to start on the box the other day, but i am for sure doing it tomorrow. here is what i'm gonna do: back chamber (sub mounted in this chamber): 3.6cuft w/ 64 sq inch port tuned to ~36hz front chamber (36hz port and sub fire into this chamber): 2.75cuft w/ 84 sq inches port tuned to ~66hz Chad, i did really use any programs to model a BP box...i just studied up and used ISD to figure out port lengths for 2 separate ported boxes. This box is gonna be pretty dam big....49"x21.5"x17.5". I ditched the idea of interchangable port on this one though...didnt really have the room i needed, but i will have an removable pannel to get the sub in and out. |

Gold Member Username: SouthernrebelMonroe, Louisiana DD 9515d~~]... Post Number: 3995 Registered: Mar-04 | Well, I got the box like 70% done today. All but 1 cut is done and its partially assembled. Ended up changing the design alil more...lol...its now 4cuft tuned to 35hz firing into 2.5cuft tuned to 65hz. I also went w/ a triple baffle (2.25") and the sub will bolt in.  what yall think bout it? |

Gold Member Username: SouthernrebelMonroe, Louisiana DD 9515d~~]... Post Number: 3996 Registered: Mar-04 | The back 4cuft(net) chamber has 52sq inches of port, 2.5cuft(net) chamber has 80sq inches of port. The 80sq inch port is going to be adjustable from 96-72sq inches...i'm gonna start w/ 80sqin first. The subs magnet will actually be in the 2.5cuft chamber...i had to re-design the box like that so i would have a large enough removable pannel to get the sub in and out. |
