Gold Member Username: DeadrabitMarionville, MO Post Number: 1788 Registered: Jun-07 | keep below 40s... unless its a burp box just make 2 boxes one tuned around 50 or the resenece of teh car and one tuned below 40 for street beat or u could make change able ports |
Gold Member Username: B3n07Louisville, Ky USA Post Number: 1072 Registered: Jul-07 | it would be for use in competitions my car peaks at 50 hrtz so i figured tuning to 48 would be good for just one L7 what do you all think |

You can drop a box in a trunk car or a SUV and tuning can drop ~10hz. Lets start by asking which vehicle you have and where you plan on placing the box. Then we can answer your question. |

Gold Member Username: B3n07Louisville, Ky USA Post Number: 1074 Registered: Jul-07 | but then wouldnt the internal volume of the box change also |
Gold Member Username: SouthernrebelMonroe, Louisiana Team Audible... Post Number: 7466 Registered: Mar-04 | No, you plug the entire port. For instance, a 2.5cuft box w/ 3-4" flared ports 15" long will tune to 48hz. Plug one, and it retunes to 40hz. What size L7 do you have? |

You can drop a box in a trunk car or a SUV and tuning can drop ~10hz." How do you figure? Your FR may change based on the dimensions of the room (or cabin in this case) due primarily to cabin gain, or the lack of it, but the box is the box. |

Sure, the box is the box. But in this case the box is going into a car, which can and will effect tuning, even if just a little. |
Gold Member Username: Drant19DUB-C, TX Post Number: 1660 Registered: Aug-07 | what would you plug the "arrow" (dblk lol) port with? |
