   Closed Enclosure Calculator ( choose Volume)


  • If only Qms and Qes are known, press Qts button to calculate Qts
  • Qms and Qes are optional
  • Fs, Qts and Vas must be entered

 
Driver Parameters
Fs : Hz - Resonant frequency  of the driver.
Qms : - Q mechanical - needed to calculate Qts
Qes : - Q electrical - needed to calculate Qts
Qts : - Total Q of the driver  
Vas : liters - Volume of air with same compliance.
  • Estimate volume of internal driver and parts (Vdr)
  • Consider the length, wide and wide when estimating
  • Enter volume of enclosure desired
Vdr : liters - Volume of internal driver and parts
Vb : liters - Volume of enclosure to calculate performance specifications
please enter estimated Box - volume!
