Speaker Box Designer / Calculator Help

  To achieve the smoothest rolloff with the box, use a Q of 1/sqrt(2) = .707   A higher Q can be used for a better bass response at certain frequencies, but this may damage the driver by causing it to bottom out (driver moves beyond the Xmax). Use caution when playing at loud volumes. The effect of different Q's is shown in the graph below.



  These are the formulas for calculating the size of a sealed box. Refer to the audio terms list for information on the different variables. In some cases, variables are used on the left and right of the = sign, as in f3 and fc. It is confusing, but these are two different variables. The driver f3 and fc variables are being used to calculate the box f3 and fc.
