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. |

What do you think? |
Bronze Member Username: PeakohmPost Number: 36 Registered: Apr-08 | i dunno if .2 is right, for a 9512 i saw .546 on their site http://www.ddaudio.com/dd/caraudio/enclosureInfo/mountingData.asp |
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 |
Platinum Member Username: Rovin1 15 = 149.1DBsTrinidad & T... Post Number: 13660 Registered: Jul-05 | it is NOT .5 sub disp thats a huge error they have on there for mths now to get an idea a 18 btl is only 0.26cuft so there is no way a 12" dd can be .5 ... |

''''''''' thats = to a 14.5sq" \cuft - try increasing the xmax a bit again & play around with some numbers ....i may sound crazy but it worked for me .... |
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... |

Bronze Member Username: PeakohmPost Number: 40 Registered: Apr-08 | nice. did you find out what the real xmax and displacement was finally though? |
Silver Member Username: Moey_gSydneyAustralia Post Number: 221 Registered: Oct-06 | Will do Rovin. Actually he didnt tell me the xmax or displacement, he just gave me several designs thatll work with the sub. Il ask him now and see what he says. |
