Silver Member Username: Moey_gSydneyAustralia Post Number: 206 Registered: Oct-06 | Hey guys i need some help in designing a box for my DD 9512. I had help here a while ago designing a box for my cvr and that turned out great. Someone here designed a box on a website and gave me the link. If someone can do that for me i will appreciate it. Thanks in advance. |

Silver Member Username: Moey_gSydneyAustralia Post Number: 217 Registered: Oct-06 | Thats quite a big difference. Even though my sub is the older 9512e, i dont think it could be that big a difference. *scratches head again* |

Silver Member Username: Moey_gSydneyAustralia Post Number: 219 Registered: Oct-06 | I just saw that the 9512b is 0.18 on the site archive pages. *Bangs head against the wall* |

Bronze Member Username: PeakohmPost Number: 39 Registered: Apr-08 | haha well at least you found what it is now right? at least for the displacement :P |

Silver Member Username: Moey_gSydneyAustralia Post Number: 220 Registered: Oct-06 | Thanks for all your help. I managed to get in contact with the DD Rep for Australia :D He sent me a few designs thatll work with the sub along with panel sizes and everything i need. Im going to use a 2.5cube box set at 40Hz. Once again thanks for all your help... |
