for a subwoofer in one program.

Solving For Length of Vent or Port

diameter of vent (Dv) = 0 = 0 centimeter |

number of ports (Np) = 0 = 0 |

volume of box (Vb) = 0 = 0 liter |

frequency of box (fb) = 0 = 0 hertz |

end correction factor (k) = 0 = 0 |

vent length (Lv) = NOT CALCULATED |

Select an equation to solve for a different unknown

Subwoofer Box and Speaker Enclosure

vent or port length | |

minimum vent or port diameter |

Note

k values:

vent has one free end and one flanged | = | 0.732 |

vent has two free ends | = | 0.614 |

vent has two flanged ends | = | 0.850 |

Where

Lv | = | length of port or vent |

Dv | = | diameter of port or vent |

Dmin | = | minimum diameter of port or vent |

Np | = | number of ports or vents |

Vb | = | volume of box |

fb or Fb | = | tuning frequency |

k | = | end correction factor |

Sd | = | surface area of subwoofer |

Vd | = | driver displacement volume |

Xmax | = | maximum linear displacement of driver |
