enter in how ever wide and tall u want the box,and it will do the rest.u enter how many cubic ft u want on there.and it gives u demensions.notice u dont enter the depth u want.that is because it tells u the depth u need to get that amount of airspace |

Not all if any enclosure design programs account for some details when calculating the enclosure's final specifications, so be mindful of what is and is not part of the design that you need to account for. |

Each program is different as to what elements they do and don't account for, but, if you looking for a list of what the elements are, here it is:
Net Volume - That which only the subwoofer requires.
Subwoofer Displacement - Volume of the subwoofer
Port Volume - Volume of the Port - round, square, slot port size.
Port Wall Volume - MDF Parts that make up port or tube.
Bracing Volume - Material used brace the interior of the enclosure. |

OK, if you use the program per the link posted, it covers all the elements with the exception of BRACING.
If your not going to use bracing, then don't sweat it. |

Chris,
There's no true accurate enclosure design program, if there were one, then there wouldn't be or the need to have so many different calculator's all over the internet.
Off hand I would say there are at the very least 10 to 15 enclosure design programs/calculators on the net right now and there are only a few that actually provide a " CUT LIST/Parts List " to make the job easier which is why they are " popular ". |

A double baffle is just using 2 sheets of MDF on top of each other to make it stronger. Instead of having the sheet be 3/4", it would be an 1.5". |

It all depends. What sub are you running, how much power? for the average system, no double baffle but a little bracing always helps... |
