Bronze Member Username: JtbPost Number: 19 Registered: Jun-04 | I was wondering how you tune a box to 30hz or 40z ect. Is it only the box dimensions that affect the frequency it is tuned at, or is it something else? Can anybody tell me or direct me to a website? Thanks. |

Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 3851 Registered: Dec-03 | the tuned frequency is determined by the box's net volume, and the diameter and length of the port(s) here: http://www.diysubwoofers.org/prt/ www.bcae1.com has calculators for ported box design, too. scan the right menu for the basic calculators topic. |
