Crossover calculators

Formulas are a good start: they give you starting values for the crossover, baffle step, Zobel and L-pad. How the crossover really sounds with your drivers only shows in a simulation with measured FRD and ZMA data – so every result opens straight as a project in Crover.

Calculators

  • Crossover calculator2-way crossover, 1st–4th order: Butterworth, Linkwitz-Riley, Bessel, E12/E24.
  • Baffle step calculatorTransition frequency from the baffle width and the matching compensation network.
  • Zobel & L-pad calculatorImpedance compensation from Re and Le, level matching at a constant load.
  • Vented box calculatorPort length for the tuning frequency fB, with end correction and the minimum port size.

Guides

  • Measure impedance with REWJig, calibration and export: your driver's impedance curve as a ZMA file.
  • Create FRD and ZMA filesMeasure and export frequency response and impedance – with REW, ARTA/LIMP or ATB.
  • The baffle step explainedWhy up to 6 dB go missing at low frequencies and how passive compensation works.
