Side Port help Please

Gold Member Username: JtownTeam RD, Texas Post Number: 2380 Registered: Mar-07 | I was wondering if someone can draw me up a box for a 12" Alpha v1 it needs to be 2.5cuft net, at 32hz, port firing to the side, sub firing to the hatch. total dimensions/space available" 37"w 15"h 15"d due to the fact that it needs to be firing to the side, the box really shouldn't be much wider than 33" in which case the depth can be increased to accomodate that. Thanks in advance for the help fellas |

Platinum Member Username: BestmankindHttp://www.rdaudio.net... Post Number: 19009 Registered: Oct-05 | well a 30 x 15 x 15 would give you approx 3 cuft. with the driver displacement and the port displacement, you should be at around 2.5 cuft. maybe a bit more. |

Gold Member Username: JtownTeam RD, Texas Post Number: 2385 Registered: Mar-07 | I don't know for sure, since it's no longer on the site. but I know that the displacement is just slightly less than the 2nd version of the alpha. sorry |

Gold Member Username: JtownTeam RD, Texas Post Number: 2388 Registered: Mar-07 | 4dr blazer. no need to "draw" it up, I just need to know dimensions for the box and port. you could use paint for a general idea, or I can generate something once i get the dimensions and ask you if that's what you had in mind |

Gold Member Username: JtownTeam RD, Texas Post Number: 2390 Registered: Mar-07 | thanks Kevin, I hadn't used subwoofer tools because I didn't wanna mess around with it to get a side firing port. sean, no problem, I was wondering why I hadn't heard from you in a few days. I'd rather not get into the external interchangable right now, just because I don't have the time to make sure it is done right. But I wouldn't mind doing the original plan we talked about: regular interchangable port, slot being 32hz, and aeros being ~47hz so yeah, just for the sake of ease right now, can you throw me some externals for a simple interchangable port, as we talked about? by tonight or even by mid day tomorrow would be absolutely great! Thanks again sean, for all the help |

Platinum Member Username: BestmankindHttp://www.rdaudio.net... Post Number: 19068 Registered: Oct-05 | actually make the box 32inches wides. let me get another one for you. |
|
Platinum Member Username: BestmankindHttp://www.rdaudio.net... Post Number: 19069 Registered: Oct-05 | this is better. a bit bigger. if you want to tune a bit higher, then just shorten the port a bit.    |
