  • Displacement: You can calculate port and driver volume displacements. For port displacement calculation, you can specify outer diameter and internal length to calculate port internal displacement. As for driver displacement, you need to enter cone diameter, voice coil diameter, magnet diameter, cone depth, magnet depth, cutout diameter, and cutout depth to calculate gross, cutout, and net internal displacement values.
  • Frequency/Time: Here, you can convert values between wavelength, cycle time, and frequency.
  • Near/Far Adjust: This tab performs near and far field calculations.
  • Woofer/Port Adjust: Here, you can compute adjustment between driver and port near field.
  • Z-Offset: It displays driver/baffle acoustic center offset calculations.
  • Frequency: It lets you view frequencies for various instruments and vocals.
  • Voltage & dB: You can perform conversion between voltage and dB units.
  • LPad: It computes resistor values for desired driver attenuation.
  • Parallel/Series: You can compute resistance, inductance, and capacitance here.
  • Port Tuning: To calculate port length and port frequency, use this tab.
  • Filters: Design filters here.
  • Curves: You can load and view measurement curves here.

You can generate HTML report for box dimension measurements and other calculations using File > Save As option. A Print option is also available in this freeware.

Overall, it is a nice speaker cabinet design software, and it is also good at other loudspeaker design calculations. It is an open source speaker box design software.
