Speaker Impedance ~ Online Calculator


Welcome to Speaker Impedance. This website calculates the nominal impedance created with different combinations of wiring speakers together. Remember calculations are only to be used as a guide; in reality, the impedance will vary with frequency and more factors such as coil temperature come into play.

TspCheck ~ Loudspeaker Thiele / Small Paramaters


As the program name suggests, TspCheck is a program that checks whether the determined or specified TS parameters of a loudspeaker match. Often you can then find out, for example, that the efficiency has been rounded up a bit too benevolently, or you can estimate the membrane mass, the resilience of the restraint, etc. by cleverly combining the information available.

In addition, the following is determined:

  • Max. Lin. SPL @ 50 Hz in CB – the maximum sound pressure that can be achieved in a closed housing at 50 Hz using the maximum linear stroke
  • SPL_m = SPL_e – the frequency from which the maximum achievable sound pressure at full input power is stroke limited.
