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.

|V = I x R||Voltage = Current x Resistance||Ohm's Law.|
|R = R1 + R2 +..||Resistance = Resist1 + Resist2 +..||Resistances connected in series add up|
|1/R = 1/R1 + 1/R2 +..||1/Resistance = 1/Resist1 + 1/Resist2 +..||The reciprocal of Resistances connected in Parallel add up|
|PA = PTotal x R / RTotal||Powerof speaker A = PowerTotal x Resistanceof speaker A / ResistanceTotal||Calculates the power going to one speaker connected in series|
