Silver Member Username: Davids2004Houston, TX USA Post Number: 684 Registered: Jun-04 | Im guessing its 23 inches long. |

Silver Member Username: Davids2004Houston, TX USA Post Number: 685 Registered: Jun-04 | I meant deep. Long deep all the same. |
|
Silver Member Username: Davids2004Houston, TX USA Post Number: 686 Registered: Jun-04 | I got about 38hz. |
|
Silver Member Username: InsearchofbassPost Number: 255 Registered: Jun-04 | 34.7 hz if your right about the depth |
|
Silver Member Username: Davids2004Houston, TX USA Post Number: 687 Registered: Jun-04 | Sean, Dont you need to subtract out the volume of the port from the area you have available. |

Bronze Member Username: InvainMichigan United States Post Number: 64 Registered: Aug-04 | do you meen depth, as in how deep the box is, or how deeo just the port is? |
|
Silver Member Username: InsearchofbassPost Number: 258 Registered: Jun-04 | you mean the depth of the wood subtracted if so i think your right |
|
Silver Member Username: InsearchofbassPost Number: 259 Registered: Jun-04 | how deep the port is |
|
Silver Member Username: InsearchofbassPost Number: 260 Registered: Jun-04 | if you subtract the depth of the wood then it would come out to about 35.2 hz |
|
Silver Member Username: InsearchofbassPost Number: 261 Registered: Jun-04 | you no what i did a test with another box that was 3.50 after displacement and i think you do subtract the depth of the wood cuz my cousins sub would only play down to 40 hz with a 9.8 inch deep port with 4 inch pvc inner diameter and it should have gone down to 39 hz but if you subtract the .75 it comes out to 40 hz |
|
Silver Member Username: InsearchofbassPost Number: 262 Registered: Jun-04 | two four inch ports 9.8 deep each minus .75 from that i meant |
|
Silver Member Username: InsearchofbassPost Number: 263 Registered: Jun-04 | my bad i forgot the .39 off so yes david is right it comes out to 38.2 hz |
