Silver Member Username: YukhuiMyrtle Beach, South Carolina USA Post Number: 371 Registered: Jan-06 | I'm not sure, something seems wrong with that box calculator. Try downloading WinISD and make yourself a box design. |

Gold Member Username: Basshead86Try Google Post Number: 8099 Registered: Aug-05 | if i were you, i would do separate chambers so you can give each sub its own port.  it will sound better, and you won't have to worry about a 4" port on each side... lol |

Post Number: 3663 Registered: Mar-04 | thats gonna be hard to do...you only have 6.8cuft (gross) to work with. build your box exactly 37"x20"x20" make the port 18.5"x 4" and 22" long. that will give you 5.4cuft (net) tuned to 35hz. |

Gold Member Username: Basshead86Try Google Post Number: 8100 Registered: Aug-05 | first of all, with your measurements(if they are external) you have a tad bit over 7 cubes, not six. and i would do separate chambers. and one 15" Type R doesn't take up half a cube of airspace iirc. |
